Below, we also provide guidelines on how to +report vulnerabilities in TensorFlow. + +## TensorFlow models are programs + +TensorFlow's runtime system interprets and executes programs. What machine +learning practitioners term +[**models**](https://developers.google.com/machine-learning/glossary/#model) are +expressed as programs that TensorFlow executes. TensorFlow programs are encoded +as computation +[**graphs**](https://developers.google.com/machine-learning/glossary/#graph). +The model's parameters are often stored separately in **checkpoints**. + +At runtime, TensorFlow executes the computation graph using the parameters +provided. Note that the behavior of the computation graph may change +depending on the parameters provided. TensorFlow itself is not a sandbox. When +executing the computation graph, TensorFlow may read and write files, send and +receive data over the network, and even spawn additional processes. All these +tasks are performed with the permissions of the TensorFlow process. Allowing +for this flexibility makes for a powerful machine learning platform, +but it has implications for security. + +The computation graph may also accept **inputs**. Those inputs are the +data you supply to TensorFlow to train a model, or to use a model to run +inference on the data. + +**TensorFlow models are programs, and need to be treated as such from a security +perspective.** + +## Running untrusted models + +As a general rule: **Always** execute untrusted models inside a sandbox (e.g., +[nsjail](https://github.com/google/nsjail)). + +There are several ways in which a model could become untrusted. Obviously, if an +untrusted party supplies TensorFlow kernels, arbitrary code may be executed. +The same is true if the untrusted party provides Python code, such as the +Python code that generates TensorFlow graphs. + +Even if the untrusted party only supplies the serialized computation +graph (in form of a `GraphDef`, `SavedModel`, or equivalent on-disk format), the +set of computation primitives available to TensorFlow is powerful enough that +you should assume that the TensorFlow process effectively executes arbitrary +code. One common solution is to whitelist only a few safe Ops. While this is +possible in theory, we still recommend you sandbox the execution. + +It depends on the computation graph whether a user provided checkpoint is safe. +It is easily possible to create computation graphs in which malicious +checkpoints can trigger unsafe behavior. For example, consider a graph that +contains a `tf.cond` depending on the value of a `tf.Variable`. One branch of +the `tf.cond` is harmless, but the other is unsafe. Since the `tf.Variable` is +stored in the checkpoint, whoever provides the checkpoint now has the ability to +trigger unsafe behavior, even though the graph is not under their control. + +In other words, graphs can contain vulnerabilities of their own. To allow users +to provide checkpoints to a model you run on their behalf (e.g., in order to +compare model quality for a fixed model architecture), you must carefully audit +your model, and we recommend you run the TensorFlow process in a sandbox. + +## Accepting untrusted Inputs + +It is possible to write models that are secure in a sense that they can safely +process untrusted inputs assuming there are no bugs. There are two main reasons +to not rely on this: first, it is easy to write models which must not be exposed +to untrusted inputs, and second, there are bugs in any software system of +sufficient complexity. Letting users control inputs could allow them to trigger +bugs either in TensorFlow or in dependent libraries. + +In general, it is good practice to isolate parts of any system which is exposed +to untrusted (e.g., user-provided) inputs in a sandbox. + +A useful analogy to how any TensorFlow graph is executed is any interpreted +programming language, such as Python. While it is possible to write secure +Python code which can be exposed to user supplied inputs (by, e.g., carefully +quoting and sanitizing input strings, size-checking input blobs, etc.), it is +very easy to write Python programs which are insecure. Even secure Python code +could be rendered insecure by a bug in the Python interpreter, or in a bug in a +Python library used (e.g., +[this one](https://www.cvedetails.com/cve/CVE-2017-12852/)). + +## Running a TensorFlow server + +TensorFlow is a platform for distributed computing, and as such there is a +TensorFlow server (`tf.train.Server`). **The TensorFlow server is meant for +internal communication only. It is not built for use in an untrusted network.** + +For performance reasons, the default TensorFlow server does not include any +authorization protocol and sends messages unencrypted. It accepts connections +from anywhere, and executes the graphs it is sent without performing any checks. +Therefore, if you run a `tf.train.Server` in your network, anybody with +access to the network can execute what you should consider arbitrary code with +the privileges of the process running the `tf.train.Server`. + +When running distributed TensorFlow, you must isolate the network in which the +cluster lives. Cloud providers provide instructions for setting up isolated +networks, which are sometimes branded as "virtual private cloud." Refer to the +instructions for +[GCP](https://cloud.google.com/compute/docs/networks-and-firewalls) and +[AWS](https://aws.amazon.com/vpc/)) for details. + +Note that `tf.train.Server` is different from the server created by +`tensorflow/serving` (the default binary for which is called `ModelServer`). +By default, `ModelServer` also has no built-in mechanism for authentication. +Connecting it to an untrusted network allows anyone on this network to run the +graphs known to the `ModelServer`. This means that an attacker may run +graphs using untrusted inputs as described above, but they would not be able to +execute arbitrary graphs. It is possible to safely expose a `ModelServer` +directly to an untrusted network, **but only if the graphs it is configured to +use have been carefully audited to be safe**. + +Similar to best practices for other servers, we recommend running any +`ModelServer` with appropriate privileges (i.e., using a separate user with +reduced permissions). In the spirit of defense in depth, we recommend +authenticating requests to any TensorFlow server connected to an untrusted +network, as well as sandboxing the server to minimize the adverse effects of +any breach. + +## Vulnerabilities in TensorFlow + +TensorFlow is a large and complex system. It also depends on a large set of +third party libraries (e.g., `numpy`, `libjpeg-turbo`, PNG parsers, `protobuf`). +It is possible that TensorFlow or its dependent libraries contain +vulnerabilities that would allow triggering unexpected or dangerous behavior +with specially crafted inputs. + +### What is a vulnerability? + +Given TensorFlow's flexibility, it is possible to specify computation graphs +which exhibit unexpected or unwanted behavior. The fact that TensorFlow models +can perform arbitrary computations means that they may read and write files, +communicate via the network, produce deadlocks and infinite loops, or run out +of memory. It is only when these behaviors are outside the specifications of the +operations involved that such behavior is a vulnerability. + +A `FileWriter` writing a file is not unexpected behavior and therefore is not a +vulnerability in TensorFlow. A `MatMul` allowing arbitrary binary code execution +**is** a vulnerability. + +This is more subtle from a system perspective. For example, it is easy to cause +a TensorFlow process to try to allocate more memory than available by specifying +a computation graph containing an ill-considered `tf.tile` operation. TensorFlow +should exit cleanly in this case (it would raise an exception in Python, or +return an error `Status` in C++). However, if the surrounding system is not +expecting the possibility, such behavior could be used in a denial of service +attack (or worse). Because TensorFlow behaves correctly, this is not a +vulnerability in TensorFlow (although it would be a vulnerability of this +hypothetical system). + +As a general rule, it is incorrect behavior for Tensorflow to access memory it +does not own, or to terminate in an unclean way. Bugs in TensorFlow that lead to +such behaviors constitute a vulnerability. + +One of the most critical parts of any system is input handling. If malicious +input can trigger side effects or incorrect behavior, this is a bug, and likely +a vulnerability. + +### Reporting vulnerabilities + +Please email reports about any security related issues you find to +`security@tensorflow.org`. This mail is delivered to a small security team. Your +email will be acknowledged within one business day, and you'll receive a more +detailed response to your email within 7 days indicating the next steps in +handling your report. For critical problems, you may encrypt your report (see +below). + +Please use a descriptive subject line for your report email. After the initial +reply to your report, the security team will endeavor to keep you informed of +the progress being made towards a fix and announcement. + +In addition, please include the following information along with your report: + +* Your name and affiliation (if any). +* A description the technical details of the vulnerabilities. It is very + important to let us know how we can reproduce your findings. +* An explanation who can exploit this vulnerability, and what they gain when + doing so -- write an attack scenario. This will help us evaluate your report + quickly, especially if the issue is complex. +* Whether this vulnerability public or known to third parties. If it is, please + provide details. + +If you believe that an existing (public) issue is security-related, please send +an email to `security@tensorflow.org`. The email should include the issue ID and +a short description of why it should be handled according to this security +policy. + +Once an issue is reported, TensorFlow uses the following disclosure process: + +* When a report is received, we confirm the issue and determine its severity. +* If we know of specific third-party services or software based on TensorFlow + that require mitigation before publication, those projects will be notified. +* An advisory is prepared (but not published) which details the problem and + steps for mitigation. +* Wherever possible, fixes are prepared for the last minor release of the two + latest major releases, as well as the master branch. We will attempt to + commit these fixes as soon as possible, and as close together as + possible. +* Patch releases are published for all fixed released versions, a + notification is sent to discuss@tensorflow.org, and the advisory is published. + +Past security advisories are listed below. We credit reporters for identifying +security issues, although we keep your name confidential if you request it. + +#### Encryption key for `security@tensorflow.org` + +If your disclosure is extremely sensitive, you may choose to encrypt your +report using the key below. Please only use this for critical security +reports. + +``` +-----BEGIN PGP PUBLIC KEY BLOCK----- + +mQENBFpqdzwBCADTeAHLNEe9Vm77AxhmGP+CdjlY84O6DouOCDSq00zFYdIU/7aI +LjYwhEmDEvLnRCYeFGdIHVtW9YrVktqYE9HXVQC7nULU6U6cvkQbwHCdrjaDaylP +aJUXkNrrxibhx9YYdy465CfusAaZ0aM+T9DpcZg98SmsSml/HAiiY4mbg/yNVdPs +SEp/Ui4zdIBNNs6at2gGZrd4qWhdM0MqGJlehqdeUKRICE/mdedXwsWLM8AfEA0e +OeTVhZ+EtYCypiF4fVl/NsqJ/zhBJpCx/1FBI1Uf/lu2TE4eOS1FgmIqb2j4T+jY +e+4C8kGB405PAC0n50YpOrOs6k7fiQDjYmbNABEBAAG0LVRlbnNvckZsb3cgU2Vj +dXJpdHkgPHNlY3VyaXR5QHRlbnNvcmZsb3cub3JnPokBTgQTAQgAOBYhBEkvXzHm +gOJBnwP4Wxnef3wVoM2yBQJaanc8AhsDBQsJCAcCBhUKCQgLAgQWAgMBAh4BAheA +AAoJEBnef3wVoM2yNlkIAICqetv33MD9W6mPAXH3eon+KJoeHQHYOuwWfYkUF6CC +o+X2dlPqBSqMG3bFuTrrcwjr9w1V8HkNuzzOJvCm1CJVKaxMzPuXhBq5+DeT67+a +T/wK1L2R1bF0gs7Pp40W3np8iAFEh8sgqtxXvLGJLGDZ1Lnfdprg3HciqaVAiTum +HBFwszszZZ1wAnKJs5KVteFN7GSSng3qBcj0E0ql2nPGEqCVh+6RG/TU5C8gEsEf +3DX768M4okmFDKTzLNBm+l08kkBFt+P43rNK8dyC4PXk7yJa93SmS/dlK6DZ16Yw +2FS1StiZSVqygTW59rM5XNwdhKVXy2mf/RtNSr84gSi5AQ0EWmp3PAEIALInfBLR +N6fAUGPFj+K3za3PeD0fWDijlC9f4Ety/icwWPkOBdYVBn0atzI21thPRbfuUxfe +zr76xNNrtRRlbDSAChA1J5T86EflowcQor8dNC6fS+oHFCGeUjfEAm16P6mGTo0p +osdG2XnnTHOOEFbEUeWOwR/zT0QRaGGknoy2pc4doWcJptqJIdTl1K8xyBieik/b +nSoClqQdZJa4XA3H9G+F4NmoZGEguC5GGb2P9NHYAJ3MLHBHywZip8g9oojIwda+ +OCLL4UPEZ89cl0EyhXM0nIAmGn3Chdjfu3ebF0SeuToGN8E1goUs3qSE77ZdzIsR +BzZSDFrgmZH+uP0AEQEAAYkBNgQYAQgAIBYhBEkvXzHmgOJBnwP4Wxnef3wVoM2y +BQJaanc8AhsMAAoJEBnef3wVoM2yX4wIALcYZbQhSEzCsTl56UHofze6C3QuFQIH +J4MIKrkTfwiHlCujv7GASGU2Vtis5YEyOoMidUVLlwnebE388MmaJYRm0fhYq6lP +A3vnOCcczy1tbo846bRdv012zdUA+wY+mOITdOoUjAhYulUR0kiA2UdLSfYzbWwy +7Obq96Jb/cPRxk8jKUu2rqC/KDrkFDtAtjdIHh6nbbQhFuaRuWntISZgpIJxd8Bt +Gwi0imUVd9m9wZGuTbDGi6YTNk0GPpX5OMF5hjtM/objzTihSw9UN+65Y/oSQM81 +v//Fw6ZeY+HmRDFdirjD7wXtIuER4vqCryIqR6Xe9X8oJXz9L/Jhslc= +=CDME +-----END PGP PUBLIC KEY BLOCK----- +``` + +### Known vulnerabilities + +| Type | Versions affected | Reported by | Additional Information | +|--------------------|:-----------------:|-----------------------|-----------------------------| +| Out Of Bounds Read | <=1.4 | Blade Team of Tencent | [issue report](https://github.com/tensorflow/tensorflow/issues/14959) | + diff --git a/WORKSPACE b/WORKSPACE index 1e38a9a8cd754886fc5232531816b875de0879a3..11c5cdb2070e79b16540a39f13cab28608962340 100644 --- a/WORKSPACE +++ b/WORKSPACE @@ -14,6 +14,12 @@ load("@io_bazel_rules_closure//closure:defs.bzl", "closure_repositories") closure_repositories() +# We must check the bazel version before trying to parse any other BUILD +# files, in case the parsing of those build files depends on the bazel +# version we require here. +load("//tensorflow:version_check.bzl", "check_bazel_version_at_least") +check_bazel_version_at_least("0.10.0") + load("//tensorflow:workspace.bzl", "tf_workspace") # Uncomment and update the paths in these entries to build the Android demo. diff --git a/configure b/configure index 9c21d2b03a27714f05094667691e74c16fa89f35..66b66ba54ed68a9aa0ee556f84f68c3a83a495ab 100755 --- a/configure +++ b/configure @@ -8,7 +8,8 @@ if [ -z "$PYTHON_BIN_PATH" ];

Each of these would be an - # independent starting point for a Markov chain. - state = tf.get_variable( - 'state',initializer=tf.random_normal([1000, n], mean=3.0, - dtype=tf.float64, seed=42)) - - # Computes the log(p(x)) for the unit normal density and ignores the - # normalization constant. - def log_density(x): - return - tf.reduce_sum(x * x, reduction_indices=-1) / 2.0 - - # Initial log-density value - state_log_density = tf.get_variable( - 'state_log_density', initializer=log_density(state.initialized_value())) - - # A variable to store the log_acceptance_ratio: - log_acceptance_ratio = tf.get_variable( - 'log_acceptance_ratio', initializer=tf.zeros([1000], dtype=tf.float64)) - - # Generates random proposals by moving each coordinate uniformly and - # independently in a box of size 2 centered around the current value. - # Returns the new point and also the log of the Hastings ratio (the - # ratio of the probability of going from the proposal to origin and the - # probability of the reverse transition).

Stands for the log of Metropolis-Hastings - acceptance ratio after propagating the chain for `n_steps`. - log_unnormalized_prob_fn: A Python callable evaluated at - `current_state` and returning a float-like `Tensor` of log target-density - up to a normalizing constant. In other words, - `log_unnormalized_prob_fn(x) = log(g(x))`, where - `target_density = g(x)/Z` for some constant `A`. The shape of the input - tensor is the same as the shape of the `current_state`. The shape of the - output tensor is either - (a). Same as the input shape if the density being sampled is one - dimensional, or - (b). If the density is defined for `events` of shape - `event_shape = [E1, E2, ... Ee]`, then the input tensor should be of - shape `batch_shape + event_shape`, here `batch_shape = [B1, ..., Bb]` - and the result must be of shape [B1, ..., Bb]. For example, if the - distribution that is being sampled is a 10 dimensional normal, - then the input tensor may be of shape [100, 10] or [30, 20, 10]. The - last dimension will then be 'consumed' by `log_unnormalized_prob_fn` - and it should return tensors of shape [100] and [30, 20] respectively. - proposal_fn: A callable accepting a real valued `Tensor` of current sample - points and returning a tuple of two `Tensors`. The first element of the - pair should be a `Tensor` containing the proposal state and should have - the same shape as the input `Tensor`. The second element of the pair gives - the log of the ratio of the probability of transitioning from the - proposal points to the input points and the probability of transitioning - from the input points to the proposal points. If the proposal is - symmetric, i.e. - Probability(Proposal -> Current) = Probability(Current -> Proposal) - the second value should be set to None instead of explicitly supplying a - tensor of zeros.

They are exposed under `tf.estimator`. +`DNNEstimator`, `LinearEstimator` and `DNNLinearCombinedEstimator` +are exposed under `tf.contrib.estimator`. + +To migrate to the new api, users need to take the following steps: + +* Replace `tf.contrib.learn` with `tf.estimator`. +* If you subclass any of the estimators, stop doing that. You should be able to + write a factory method that returns a canned estimator instead. If this is not + possible (if you override methods from the canned estimator), consider writing + a custom estimator instead. See `tf.estimator.Estimator`. +* Set `loss_reduction=tf.losses.Reduction.SUM_OVER_BATCH_SIZE` to preserve loss + reduction as the average over batch. +* Some optimizer-related arguments are no longer passed in the estimator + constructor. Instead, we provide methods that perform the same job by wrapping + an optimizer. Specifically: + * `gradient_clip_norm`: Use `tf.contrib.estimator.clip_gradients_by_norm` + * `embedding_lr_multipliers`: Not supported. + Other arguments: + * `input_layer_min_slice_size`: Replaced by `input_layer_partitioner` + * `enable_centered_bias`: Not supported.

You can call your + `feature_engineering_fn` inside your input_fn: + ```python + def new_input_fn(): + features, labels = old_input_fn() + return feature_engineering_fn(features, labels) + ``` +* Use `tf.reshape` to reshape labels in your `input_fn`. `tf.estimator` + classifiers and regressors expect labels as a 2D Tensor of shape + `[batch_size, 1]`, or `[batch_size, n_labels]`. In contrast, + `tf.contrib.learn` classifiers and regressors supported labels with shape + `[batch_size]`. +* If you pass custom metrics from the `evaluate()` method call, use + `tf.contrib.estimator.add_metrics`. +* Replace your `serving_input_fn` with a `serving_input_receiver_fn`. + Note this should be entirely distinct from your training `input_fn`, so if you + previously had one `input_fn` with different "modes", you should now factor + that apart. Where the former returned either a simple `(features, labels)` + tuple or `InputFnOps`, you should now return a `ServingInputReceiver`. + If you were generating your `serving_input_fn` using the + `build_parsing_serving_input_fn` helper, you can simply drop in the + replacement `build_parsing_serving_input_receiver_fn`. + +Some remaining estimators/classes: + +* `DynamicRnnEstimator`: Consider a custom `model_fn`. +* `KMeansClustering`: Use `tf.contrib.factorization.KMeansClustering`. +* `LogisticRegressor`: Not supported.

If you use `multi_head`, refer to + `tf.contrib.estimator.multi_head` documentation. + +## Experiment Class - Distributed Training Tooling + +Switch to `tf.estimator.train_and_evaluate`. Some differences: + +* Most of the constructor arguments, like `train_input_fn`, `eval_input_fn`, + should be wrapped into `tf.estimator.TrainSpec` and `tf.estimator.EvalSpec`. +* Remove the `experiment_fn`. Instead, create the `Estimator`, + `train_spec` and `eval_spec`, then call `tf.estimator.train_and_evaluate` + directly. +* Inside `tf.estimator.EvalSpec`, the `exporter` field is the replacement + for `export_strategy`. To be precise, `tf.estimator.LatestExporter` is the + replacement for `tf.contrib.learn.make_export_strategy`. If you want to export + only at the end of training use `tf.estimator.FinalExporter`. +* If the `TF_CONFIG` environment variable is constructed manually, please read + the `train_and_evaluate` documentation for the new requirementds (in + particular, the chief node and evaluator node). + +## Others Classes and Functions + +* `tf.contrib.learn.datasets` is deprecated. We are adding ready to use datasets + to tensorflow/models. Many smaller datasets are available from other sources, + such as scikits.learn. Some Python processing may have to be written, but this + is straightforward to implement using the standard modules. +* `tf.contrib.learn.preprocessing`: Deprecated. The python-only preprocessing + functions are not a good fit for TensorFlow. Please use `tf.data`, and + consider tensorflow/transform for more complex use cases. +* `tf.contrib.learn.models`: Not supported, use canned estimators instead. +* `tf.contrib.learn.monitors`: Implement `SessionRunHook` instead. Hook + implementations are in `tf.train`. +* `tf.contrib.learn.learn_io`: Use the methods in `tf.estimator.inputs`, such as + `tf.estimator.inputs.numpy_input_fn`. Some utility functions have no + equivalent, we encourage the use of `tf.data`. + diff --git a/tensorflow/contrib/learn/__init__.py b/tensorflow/contrib/learn/__init__.py index 3698af027e38f1063ad829c26eb179734968f813..79bd73faaf1301a2fc4999b64f88d30542577980 100644 --- a/tensorflow/contrib/learn/__init__.py +++ b/tensorflow/contrib/learn/__init__.py @@ -13,8 +13,11 @@ # limitations under the License. # ============================================================================== -# TODO(ptucker,ipolosukhin): Improve descriptions. -"""High level API for learning. +"""High level API for learning (DEPRECATED). + +This module and all its submodules are deprecated.

Its interface is aimed only at inference, so it provides the ability to load a graph, set up inputs, and run the model to calculate particular outputs. The full documentation for the set of methods can be seen [here](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/contrib/lite/g3doc/).

We might eventually standardize on a single supported value, e.g. 4, +// and drop that template parameter. The reason why it can't be a runtime +// parameter is that this controls the fixed-point format used, i.e. we need to +// generate actually different code based on it. In particular, we generate code +// for a fixed-point tanh() implementation for that format, which internally +// uses a fixed-point exp() implementation, which internally uses a +// barrel-shifter with a number of steps that depends on StateIntegerBits. +// Another consequence of that is that a higher value of StateIntegerBits +// results in a more expensive implementation (more barrel shifter steps +// needed). +// +// +// === Why [-8, 8] for fully-connected output? === +// +// This array is only fed to Logistic and Tanh functions, for which +// the quantized implementation will want to use fixed-point arithmetic, +// requiring a power-of-two representation interval. Thus, we should right +// away quantize this array to a power-of-two interval; otherwise, +// implementation will need to rescale that, losing any benefit that a tighter +// representation interval might otherwise yield, while introducting some +// numerical error and computational overhead. +// +// Now, Logistic and Tanh +// are nearly constant (nearly equal to their horizontal asymptotes) +// outside of a small bounded interval around 0: +// +// Logistic(4) = 1 - 1.8e-2 Tanh(4) = 1 - 6.7e-4 +// Logistic(8) = 1 - 3.4e-4 Tanh(8) = 1 - 2.3e-7 +// Logistic(16) = 1 - 1.1e-7 Tanh(16) = 1 - 2.5e-14 +// +// From this, we see that clamping to [-4, 4] would be too inaccurate +// (the error of 1.8e-2 on Logistic would be felt even in 8bit precision) +// while clamping to [-16, 16] would make no difference even in float32. +// However, for a fixed-point implementation in 16-bit integers, using 5 +// integer bits to represent the [-16, 16] range would leave only 11 +// fractional bits, giving an increment of 2^-11 = 4.9e-4 between consecutive +// representable values. Notice that that is higher than the +// worst-case clamping error with clamping to [-8, 8]: 3.4e-4 for Logistic. +// Using [-8, 8] thus seems like the better compromise overall, enjoying +// an increment of 2.4e-4 between representable values and a worst-case +// clamping error of 3.4e-4, both better than the increment of 4.9e-4 with +// [-16, 16]. +// +// Moreover, all other things being equal, it is nice to choose the narrower +// representation range, as that makes the implementation of fixed-point +// math functions a little cheaper (each integer bit requires an additional +// barrel-shifter atep in the implementation of exp(-x)). That is further +// reason to prefer [-8, 8] over [-16, 16]. The choice of [-16, 16] would make +// sense for 32-bit float or 32-bit fixed-point quantization, but we are +// aiming for 16-bit fixed-point quantization of these internal nodes here. +// +template +void LstmCell(const uint8* input_data_uint8, const Dims<4>& input_dims, + const uint8* prev_activ_data_uint8, + const Dims<4>& prev_activ_dims, const uint8* weights_data_uint8, + const Dims<4>& weights_dims, const int32* bias_data_int32, + const Dims<4>& bias_dims, const int16* prev_state_data_int16, + const Dims<4>& prev_state_dims, int16* output_state_data_int16, + const Dims<4>& output_state_dims, uint8* output_activ_data_uint8, + const Dims<4>& output_activ_dims, uint8* concat_temp_data_uint8, + const Dims<4>& concat_temp_dims, int16* activ_temp_data_int16, + const Dims<4>& activ_temp_dims, int32 weights_zero_point, + int32 accum_multiplier, int accum_shift, + gemmlowp::GemmContext* gemm_context) { + (void)gemm_context; // only used in optimized code. + + // Gather dimensions information, and perform consistency checks. + const int batches = + MatchingArraySize(input_dims, 3, prev_activ_dims, 3, prev_state_dims, 3, + output_state_dims, 3, output_activ_dims, 3); + const int height = + MatchingArraySize(input_dims, 2, prev_activ_dims, 2, prev_state_dims, 2, + output_state_dims, 2, output_activ_dims, 2); + const int width = + MatchingArraySize(input_dims, 1, prev_activ_dims, 1, prev_state_dims, 1, + output_state_dims, 1, output_activ_dims, 1); + TFLITE_CHECK_EQ(ArraySize(weights_dims, 2), 1); + TFLITE_CHECK_EQ(ArraySize(weights_dims, 3), 1); + const int input_depth = ArraySize(input_dims, 0); + const int prev_activ_depth = ArraySize(prev_activ_dims, 0); + const int total_input_depth = prev_activ_depth + input_depth; + TFLITE_CHECK_EQ(ArraySize(weights_dims, 0), total_input_depth); + TFLITE_CHECK_EQ(MatchingArraySize(bias_dims, 1, bias_dims, 2, bias_dims, 3), + 1); + const int intern_activ_depth = + MatchingArraySize(weights_dims, 1, bias_dims, 0); + TFLITE_CHECK_EQ(intern_activ_depth % 4, 0); + const int output_depth = + MatchingArraySize(prev_state_dims, 0, prev_activ_dims, 0, + output_state_dims, 0, output_activ_dims, 0); + TFLITE_CHECK_EQ(output_depth, intern_activ_depth / 4); + const int fc_batches = ArraySize(activ_temp_dims, 1) * + ArraySize(activ_temp_dims, 2) * + ArraySize(activ_temp_dims, 3); + const int fc_output_depth = + MatchingArraySize(weights_dims, 1, activ_temp_dims, 0); + const int fc_accum_depth = ArraySize(weights_dims, 0); + TFLITE_CHECK_EQ(fc_output_depth, 4 * output_depth); + + // Depth-concatenate prev_activ and input data together. + uint8 const* concat_input_arrays_data[2] = {input_data_uint8, + prev_activ_data_uint8}; + Dims<4> const* concat_input_arrays_dims[2] = {&input_dims, &prev_activ_dims}; + Concatenation( + 0, concat_input_arrays_data, concat_input_arrays_dims, 2, + concat_temp_data_uint8, concat_temp_dims); + + // Implementation of the fully connected node inside the LSTM cell. + // The operands are 8-bit integers, the accumulators are internally 32bit + // integers, and the output is 16-bit fixed-point with 3 integer bits so + // the output range is [-2^3, 2^3] == [-8, 8].

subgraph in TensorRT. This is still a work in progress +but should be useable with most common graphs. + +## Compilation + + +In order to compile the module, you need to have a local TensorRT +installation ( libnvinfer.so and respective include files ). During the +configuration step, TensorRT should be enabled and installation path +should be set. If installed through package managers (deb,rpm), +configure script should find the necessary components from the system +automatically. If installed from tar packages, user has to set path to +location where the library is installed during configuration. + +```shell +bazel build --config=cuda --config=opt //tensorflow/tools/pip_package:build_pip_package +bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/ +``` + +After the installation of tensorflow package, TensorRT transformation +will be available. An example use can be found in test/test_tftrt.py script + +## Installing TensorRT 3.0.4 + +In order to make use of TensorRT integration, you will need a local installation of TensorRT 3.0.4 from the [NVIDIA Developer website](https://developer.nvidia.com/tensorrt). Due to compiler compatibility, you will need to download and install the TensorRT 3.0.4 tarball for _Ubuntu 14.04_, i.e., **_TensorRT-3.0.4.Ubuntu-14.04.5.x86_64.cuda-9.0.cudnn7.0-tar.gz_**, even if you are using Ubuntu 16.04 or later. + +### Preparing TensorRT installation + +Once you have downloaded TensorRT-3.0.4.Ubuntu-14.04.5.x86_64.cuda-9.0.cudnn7.0-tar.gz, you will need to unpack it to an installation directory, which will be referred to as . Please replace with the full path of actual installation directory you choose in commands below. + +```shell +cd && tar -zxf /path/to/TensorRT-3.0.4.Ubuntu-14.04.5.x86_64.cuda-9.0.cudnn7.0-tar.gz +``` + +After unpacking the binaries, you have several options to use them: + +#### To run TensorFlow as a user without superuser privileges + +For a regular user without any sudo rights, you should add TensorRT to your `$LD_LIBRARY_PATH`: + + ```shell + export LD_LIBRARY_PATH=/TensorRT-3.0.4/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}} + ``` + +Then you are ready to use TensorFlow-TensorRT integration. `$LD_LIBRARY_PATH` must contain the path to TensorRT installation for TensorFlow-TensorRT integration to work. If you are using a VirtualEnv-like setup, you can add the command above to your `bin/activate` script or to your `.bashrc` script. + +#### To run TensorFlow as a superuser + + When running as a superuser, such as in a container or via sudo, the `$LD_LIBRARY_PATH` approach above may not work. The following is preferred when the user has superuser privileges: + + ```shell + echo "/TensorRT-3.0.4/lib" | sudo tee /etc/ld.so.conf.d/tensorrt304.conf && sudo ldconfig + ``` + + Please ensure that any existing deb package installation of TensorRT is removed before following these instructions to avoid package conflicts. \ No newline at end of file diff --git a/tensorflow/contrib/tensorrt/__init__.py b/tensorflow/contrib/tensorrt/__init__.py new file mode 100644 index 0000000000000000000000000000000000000000..140ad4828208ae4844a49bf664955b50cd9e51cd --- /dev/null +++ b/tensorflow/contrib/tensorrt/__init__.py @@ -0,0 +1,35 @@ +# Copyright 2018 The TensorFlow Authors.

An RDMA path is added between servers fo During the server setup, an RDMA manager is created to manage low-level RDMA components such as RDMA channel and RDMA adapter, an RDMA rendezvous manager is created to oversee send/recv operations between servers. Following the distributed TensorFlow design philosophy, the send operation is passive, i.e. merely placing a tensor in the local out-going table. It is the receive operation that actually initiates the tensor transfer. TensorFlow dynamically allocates memory for tensors that are to be sent or received. This causes difficulty for RDMA operations where pinned memory is required. Few remedies are possible: -1. The memory is pinned, transfered, then unpinned for each and every tensor to be transferred. This incurs significant operation overhead since pinning and unpinning memory for each dynamically generated tensor is slow. +1.

One of the -magical qualities of deep networks is that they tend to cope very well with high -levels of noise in their inputs.

This is a lot more difficult since it requires changes everywhere -you do calculations, but offers a lot of potential rewards. Fetching eight-bit -values only requires 25% of the memory bandwidth of floats, so you'll make much -better use of caches and avoid bottlenecking on RAM access. You can also -typically use SIMD operations that do many more operations per clock cycle. In -some case you'll have a DSP chip available that can accelerate eight-bit -calculations too, which can offer a lot of advantages. - -Moving calculations over to eight bit will help you run your models faster, and -use less power (which is especially important on mobile devices).

Using floating +point arithmetic is an easy way to preserve accuracy and GPUs are designed to +accelerate these calculations. + +However, as more machine learning models are deployed to mobile devices, +inference efficiency has become a critical issue. Where the computational demand +for *training* grows with the amount of models trained on different +architectures, the computational demand for *inference* grows in proportion to +the amount of users. + +## Quantization benefits + + +Using 8-bit calculations help your models run faster and use less power. This is +especially important for mobile devices and embedded applications that can't run +floating point code efficiently, for example, Internet of Things (IoT) and +robotics devices. There are additional opportunities to extend this support to +more backends and research lower precision networks. + +### Smaller file sizes {: .hide-from-toc} + +Neural network models require a lot of space on disk. For example, the original +AlexNet requires over 200 MB for the float format—almost all of that for the +model's millions of weights. Because the weights are slightly different +floating point numbers, simple compression formats perform poorly (like zip). + +Weights fall in large layers of numerical values. For each layer, weights tend to +be normally distributed within a range. Quantization can shrink file sizes by +storing the minimum and maximum weight for each layer, then compress each +weight's float value to an 8-bit integer representing the closest real number in +a linear set of 256 within the range. + +### Faster inference {: .hide-from-toc} + +Since calculations are run entirely on 8-bit inputs and outputs, quantization +reduces the computational resources needed for inference calculations. This is +more involved, requiring changes to all floating point calculations, but results +in a large speed-up for inference time. + +### Memory efficiency {: .hide-from-toc} + +Since fetching 8-bit values only requires 25% of the memory bandwidth of floats, +more efficient caches avoid bottlenecks for RAM access. In many cases, the power +consumption for running a neural network is dominated by memory access. The +savings from using fixed-point 8-bit weights and activations are significant. + +Typically, SIMD operations are available that run more operations per clock +cycle. In some cases, a DSP chip is available that accelerates 8-bit calculations +resulting in a massive speedup. + +## Fixed point quantization techniques + +The goal is to use the same precision for weights and activations during both +training and inference. But an important difference is that training consists of +a forward pass and a backward pass, while inference only uses a forward pass. +When we train the model with quantization in the loop, we ensure that the forward +pass matches precision for both training and inference. + +To minimize the loss in accuracy for fully fixed point models (weights and +activations), train the model with quantization in the loop. This simulates +quantization in the forward pass of a model so weights tend towards values that +perform better during quantized inference. The backward pass uses quantized +weights and activations and models quantization as a straight through estimator. +(See Bengio et al., [2013](https://arxiv.org/abs/1308.3432)) + +Additionally, the minimum and maximum values for activations are determined +during training. This allows a model trained with quantization in the loop to be +converted to a fixed point inference model with little effort, eliminating the +need for a separate calibration step. + +## Quantization training with TensorFlow + +TensorFlow can train models with quantization in the loop. Because training +requires small gradient adjustments, floating point values are still used. To +keep models as floating point while adding the quantization error in the training +loop, @{$array_ops#Fake_quantization$fake quantization} nodes simulate the +effect of quantization in the forward and backward passes. + +Since it's difficult to add these fake quantization operations to all the +required locations in the model, there's a function available that rewrites the +training graph. To create a fake quantized training graph: + +``` +# Build forward pass of model. +loss = tf.losses.get_total_loss() + +# Call the training rewrite which rewrites the graph in-place with +# FakeQuantization nodes and folds batchnorm for training. It is +# often needed to fine tune a floating point model for quantization +# with this training tool. When training from scratch, quant_delay +# can be used to activate quantization after training to converge +# with the float graph, effectively fine-tuning the model. +tf.contrib.quantize.create_training_graph(quant_delay=2000000) + +# Call backward pass optimizer as usual. +optimizer = tf.train.GradientDescentOptimizer(learning_rate) +optimizer.minimize(loss) ``` -This will produce a new model that runs the same operations as the original, but -with eight bit calculations internally, and all weights quantized as well. If -you look at the file size, you'll see it's about a quarter of the original (23MB -versus 91MB). You can still run this model using exactly the same inputs and -outputs though, and you should get equivalent results. Here's an example: +The rewritten *eval graph* is non-trivially different from the *training graph* +since the quantization ops affect the batch normalization step. Because of this, +we've added a separate rewrite for the *eval graph*: -```sh -bazel build tensorflow/examples/label_image:label_image -bazel-bin/tensorflow/examples/label_image/label_image \ ---graph=/tmp/quantized_graph.pb \ +``` +# Build eval model +logits = tf.nn.softmax_cross_entropy_with_logits(...) + +# Call the eval rewrite which rewrites the graph in-place with +# FakeQuantization nodes and fold batchnorm for eval. +tf.contrib.quantize.create_eval_graph() + +# Save the checkpoint and eval graph proto to disk for freezing +# and providing to TFLite. +with open(eval_graph_file, ‘w’) as f: + f.write(str(g.as_graph_def())) +saver = tf.train.Saver() +saver.save(sess, checkpoint_name) +``` + +Methods to rewrite the training and eval graphs are an active area of research +and experimentation. Although rewrites and quantized training might not work or +improve performance for all models, we are working to generalize these +techniques. + +## Generating fully quantized models + +The previously demonstrated after-rewrite eval graph only *simulates* +quantization. To generate real fixed point computations from a trained +quantization model, convert it to a fixed point kernel. Tensorflow Lite supports +this conversion from the graph resulting from `create_eval_graph`. + +First, create a frozen graph that will be the input for the TensorFlow Lite +toolchain: + +``` +bazel build tensorflow/python/tools:freeze_graph && \ + bazel-bin/tensorflow/python/tools/freeze_graph \ + --input_graph=eval_graph_def.pb \ + --input_checkpoint=checkpoint \ + --output_graph=frozen_eval_graph.pb --output_node_names=outputs ``` -You'll see that this runs the newly-quantized graph, and outputs a very similar -answer to the original. - -You can run the same process on your own models saved out as GraphDefs, with the -input and output names adapted to those your network requires. I recommend that -you run them through the freeze_graph script first, to convert checkpoints into -constants stored in the file. - -## How Does the Quantization Process Work? - -We've implemented quantization by writing equivalent eight-bit versions of -operations that are commonly used during inference. These include convolution, -matrix multiplication, activation functions, pooling operations and -concatenation. The conversion script first replaces all the individual ops it -knows about with quantized equivalents. These are small sub-graphs that have -conversion functions before and after to move the data between float and -eight-bit. Below is an example of what they look like. First here's the original -Relu operation, with float inputs and outputs: - -![Relu Diagram](https://www.tensorflow.org/images/quantization0.png) - -Then, this is the equivalent converted subgraph, still with float inputs and -outputs, but with internal conversions so the calculations are done in eight -bit. - -![Converted Diagram](https://www.tensorflow.org/images/quantization1.png) - -The min and max operations actually look at the values in the input float -tensor, and then feeds them into the Dequantize operation that converts the -tensor into eight-bits. There are more details on how the quantized representation -works later on. - -Once the individual operations have been converted, the next stage is to remove -unnecessary conversions to and from float. If there are consecutive sequences of -operations that all have float equivalents, then there will be a lot of adjacent -Dequantize/Quantize ops. This stage spots that pattern, recognizes that they -cancel each other out, and removes them, like this: - -![Stripping Diagram](https://www.tensorflow.org/images/quantization2.png) - -Applied on a large scale to models where all of the operations have quantized -equivalents, this gives a graph where all of the tensor calculations are done in -eight bit, without having to convert to float. - -## What Representation is Used for Quantized Tensors? - -We approach converting floating-point arrays of numbers into eight-bit -representations as a compression problem. We know that the weights and -activation tensors in trained neural network models tend to have values that are -distributed across comparatively small ranges (for example you might have -15 to -+15 for weights, -500 to 1000 for activations on an image model, though the -exact numbers will vary). We also know from experiment that neural nets tend to -be very robust in the face of noise, and so the noise-like error produced by -quantizing down to a small set of values will not hurt the precision of the -overall results very much. We also want to pick a representation that's easy to -perform calculations on, especially the large matrix multiplications that form -the bulk of the work that's needed to run a model. - -These led us to pick a representation that has two floats to store the overall -minimum and maximum values that are represented by the lowest and highest -quantized value. Each entry in the quantized array represents a float value in -that range, distributed linearly between the minimum and maximum. For example, -if we have minimum = -10.0, and maximum = 30.0f, and an eight-bit array, here's -what the quantized values represent: +Provide this to the TensorFlow Lite Optimizing Converter (TOCO) to get a fully +quantized TensorFLow Lite model: ``` -Quantized | Float ---------- | ----- -0 | -10.0 -255 | 30.0 -128 | 10.0 +bazel build tensorflow/contrib/lite/toco:toco && \ + ./bazel-bin/third_party/tensorflow/contrib/lite/toco/toco \ + --input_file=frozen_eval_graph.pb \ + --output_file=tflite_model.tflite \ + --input_format=TENSORFLOW_GRAPHDEF --output_format=TFLITE \ + --inference_type=QUANTIZED_UINT8 \ + --input_shape="1,224, 224,3" \ + --input_array=input \ + --output_array=outputs \ + --std_value=127.5 --mean_value=127.5 ``` -The advantages of this format are that it can represent arbitrary magnitudes of -ranges, they don't have to be symmetrical, it can represent signed and unsigned -values, and the linear spread makes doing multiplications straightforward. There -are alternatives like [Song Han's code books](http://arxiv.org/pdf/1510.00149.pdf) -that can use lower bit depths by non-linearly distributing the float values -across the representation, but these tend to be more expensive to calculate on. - -The advantage of having a strong and clear definition of the quantized format is -that it's always possible to convert back and forth from float for operations -that aren't quantization-ready, or to inspect the tensors for debugging -purposes. One implementation detail in TensorFlow that we're hoping to improve -in the future is that the minimum and maximum float values need to be passed as -separate tensors to the one holding the quantized values, so graphs can get a -bit dense! - -The nice thing about the minimum and maximum ranges is that they can often be -pre-calculated. Weight parameters are constants known at load time, so their -ranges can also be stored as constants. We often know the ranges for inputs (for -examples images are usually RGB values in the range 0.0 to 255.0), and many -activation functions have known ranges too. This can avoid having to analyze the -outputs of an operation to determine the range, which we need to do for math ops -like convolution or matrix multiplication which produce 32-bit accumulated -results from 8-bit inputs. - -## What's Next? - -We've found that we can get extremely good performance on mobile and embedded -devices by using eight-bit arithmetic rather than floating-point. You can see -the framework we use to optimize matrix multiplications at -[gemmlowp](https://github.com/google/gemmlowp). We still need to apply all the -lessons we've learned to the TensorFlow ops to get maximum performance on -mobile, but we're actively working on that. Right now, this quantized -implementation is a reasonably fast and accurate reference implementation that -we're hoping will enable wider support for our eight-bit models on a wider -variety of devices.

Additionally, as a shorthand, we define `output_gather_dims` of type +`ArraySlice` as the set of dimensions in the output shape but not in +`output_window_dims`, in ascending order. E.g. if the output tensor has rank +`5`, `output_window_dims` is {`2`, `4`} then `output_gather_dims` is {`0`, `1`, +`3`} + +If `index_vector_dim` is equal to `gather_indices.rank` we implicitly +consider `gather_indices` to have a trailing `1` dimension (i.e. if +`gather_indices` was of shape `[6,7]` and `index_vector_dim` is `2` then +we implicitly consider the shape of `gather_indices` to be `[6,7,1]`). + +The bounds for the output tensor along dimension `i` is computed as follows: + + 1. If `i` is present in `output_gather_dims` (i.e. is equal to + `output_gather_dims[k]` for some `k`) then we pick the corresponding + dimension bounds out of `gather_indices.shape`, skipping + `index_vector_dim` (i.e. pick `gather_indices.shape.dims`[`k`] if `k` + < `index_vector_dim` and `gather_indices.shape.dims`[`k`+`1`] + otherwise). + 2. If `i` is present in `output_window_dims` (i.e. equal to + `output_window_dims`[`k`] for some `k`) then we pick the corresponding + bound out of `window_bounds` after accounting for `elided_window_dims` + (i.e. we pick `adjusted_window_bounds`[`k`] where `adjusted_window_bounds` + is `window_bounds` with the bounds at indices `elided_window_dims` + removed). + +The operand index `In` corresponding to an output index `Out` is computed as +follows: + + 1. Let `G` = { `Out`[`k`] for `k` in `output_gather_dims` }. Use `G` to slice + out vector `S` such that `S`[`i`] = `gather_indices`[Combine(`G`, `i`)] + where Combine(A, b) inserts b at position `index_vector_dim` into A. + Note that this is well defined even if `G` is empty -- if `G` is empty then + `S` = `gather_indices`. + 2. Create an index, `S``in`, into `operand` using `S` by + scattering `S` using the `gather_dims_to_operand_dims` map + (`S``in` is the starting indices for _operand slice_ mentioned + above). More precisely: + 1. `S``in`[`gather_dims_to_operand_dims`[`k`]] = `S`[`k`] if `k` < + `gather_dims_to_operand_dims.size`. + 2. `S``in`[`_`] = `0` otherwise. + 3. Create an index `W``in` into `operand` by scattering the indices + at the output window dimensions in `Out` according to + the `elided_window_dims` set (`W``in` is the _window index_ + mentioned above). More precisely: + 1. `W``in`[`window_dims_to_operand_dims`(`k`)] = `Out`[`k`] if + `k` < `output_window_dims.size` (`window_dims_to_operand_dims` is + defined below). + 2. `W``in`[`_`] = `0` otherwise. + 4. `In` is `W``in` + `S``in` where + is element-wise + addition. + +`window_dims_to_operand_dims` is the monotonic function with domain [`0`, +`output_window_dims.size`) and range [`0`, `operand.rank`) \ +`elided_window_dims`. So if, e.g., `output_window_dims.size` is `4`, +`operand.rank` is `6` and `elided_window_dims` is {`0`, `2`} then +`window_dims_to_operand_dims` is {`0`→`1`, `1`→`3`, `2`→`4`, `3`→`5`}. + +### Informal Description and Examples + +`index_vector_dim` is set to `gather_indices.rank` - `1` in all of the +examples that follow. More interesting values for `index_vector_dim` +does not change the operation fundamentally, but makes the visual representation +more cumbersome. + +To get an intuition on how all of the above fits together, let's look at an +example that gathers 5 slices of shape `[8,6]` from a `[16,11]` tensor. The +position of a slice into the `[16,11]` tensor can be represented as an index +vector of shape `S64[2]`, so the set of 5 positions can be represented as a +`S64[5,2]` tensor. + +The behavior of the gather operation can then be depicted as an index +transformation that takes [`G`,`W``0`,`W``1`], an index in +the output shape, and maps it to an element in the input tensor in the following +way: + +
+ +
+ +We first select an (`X`,`Y`) vector from the gather indices tensor using `G`. +The element in the output tensor at index +[`G`,`W``0`,`W``1`] is then the element in the input +tensor at index [`X`+`W``0`,`Y`+`W``1`]. + +`window_bounds` is `[8,6]`, which decides the range of W`0` and +W`1`, and this in turn decides the bounds of the slice. + +This gather operation acts as a batch dynamic slice with `G` as the batch +dimension. + +The gather indices may be multidimensional. For instance, a more general +version of the example above using a "gather indices" tensor of shape `[4,5,2]` +would translate indices like this: + +
+ +
+ +Again, this acts as a batch dynamic slice `G``0` and +`G``1` as the batch dimensions. The window bounds are still `[8,6]`. + +The gather operation in XLA generalizes the informal semantics outlined above in +the following ways: + + 1. We can configure which dimensions in the output shape are the window + dimensions (dimensions containing `W``0`, `W``1` in + the last example). The output gather dimensions (dimensions containing + `G``0`, `G``1` in the last example) are defined to be + the output dimensions that are not window dimensions. + + 2. The number of output window dimensions explicitly present in the output + shape may be smaller than the input rank. These "missing" dimensions, which + are listed explicitly as `elided_window_dims`, must have a window bound of + `1`. Since they have a window bound of `1` the only valid index for them is + `0` and eliding them does not introduce ambiguity. + + 3. The slice extracted from the "Gather Indices" tensor ((`X`, `Y`) in the last + example) may have fewer elements than the input tensor rank, and an explicit + mapping dictates how the index should be expanded to have the same rank as + the input. + +As a final example, we use (2) and (3) to implement `tf.gather_nd`: + +
+ +
+ +`G``0` and `G``1` are used to slice out a starting index +from the gather indices tensor as usual, except the starting index has only one +element, `X`. Similarly, there is only one output window index with the value +`W``0`. However, before being used as indices into the input tensor, +these are expanded in accordance to "Gather Index Mapping" +(`gather_dims_to_operand_dims` in the formal description) and "Window Mapping" +(`window_dims_to_operand_dims` in the formal description) into +[`0`,`W``0`] and [`X`,`0`] respectively, adding up to +[`X`,`W``0`]. In other words, the output index +[`G``0`,`G``1`,`W``0`] maps to the input index +[`GatherIndices`[`G``0`,`G``1`,`0`],`X`] which gives us +the semantics for `tf.gather_nd`. + +`window_bounds` for this case is `[1,11]`. Intuitively this means that every +index `X` in the gather indices tensor picks an entire row and the result is the +concatenation of all these rows. ## GetTupleElement @@ -1075,7 +1293,7 @@ result2 = while (condition, init = result1) { ``` Nested tuple shapes are not supported.

The constructor requires two additional arguments. +You should set the `use_tpu` argument to `False`, and pass a +@{tf.contrib.tpu.RunConfig} as the `config` argument, as shown below: + +``` python +my_tpu_estimator = tf.contrib.tpu.TPUEstimator( + model_fn=my_model_fn, + config=tf.contrib.tpu.RunConfig() + use_tpu=False) +``` + +Just this simple change will allow you to run a `TPUEstimator` locally. +The majority of example TPU models can be run in this local mode, +by setting the command line flags as follows: + + +``` +$> python mnist_tpu.py --use_tpu=false --master='' +``` + +Note: This `use_tpu=False` argument is useful for trying out the `TPUEstimator` +API. It is not meant to be a complete TPU compatibility test. Successfully +running a model locally in a `TPUEstimator` does not guarantee that it will +work on a TPU. + + +### Building a `tpu.RunConfig` + +While the default `RunConfig` is sufficient for local training, these settings +cannot be ignored in real usage. + +A more typical setup for a `RunConfig`, that can be switched to use a Cloud +TPU, might be as follows: + +``` python +import tempfile +import subprocess + +class FLAGS(object): + use_tpu=False + tpu_name=None + # Use a local temporary path for the `model_dir` + model_dir = tempfile.mkdtemp() + # Number of training steps to run on the Cloud TPU before returning control. + iterations = 50 + # A single Cloud TPU has 8 shards. + num_shards = 8 + +if FLAGS.use_tpu: + my_project_name = subprocess.check_output([ + 'gcloud','config','get-value','project']) + my_zone = subprocess.check_output([ + 'gcloud','config','get-value','compute/zone']) + cluster_resolver = tf.contrib.cluster_resolver.TPUClusterResolver( + tpu_names=[FLAGS.tpu_name], + zone=my_zone, + project=my_project) + master = tpu_cluster_resolver.get_master() +else: + master = '' + +my_tpu_run_config = tf.contrib.tpu.RunConfig( + master=master, + evaluation_master=master, + model_dir=FLAGS.model_dir, + session_config=tf.ConfigProto( + allow_soft_placement=True, log_device_placement=True), + tpu_config=tf.contrib.tpu.TPUConfig(FLAGS.iterations, + FLAGS.num_shards), +) +``` + +Then you must pass the @{tf.contrib.tpu.RunConfig} to the constructor: + +``` python +my_tpu_estimator = tf.contrib.tpu.TPUEstimator( + model_fn=my_model_fn, + config = my_tpu_run_config, + use_tpu=FLAGS.use_tpu) +``` + +Typically the `FLAGS` would be set by command line arguments. To switch from +training locally to training on a cloud TPU you would need to: + +* Set `FLAGS.use_tpu` to `True` +* Set `FLAGS.tpu_name` so the `tf.contrib.cluster_resolver.TPUClusterResolver` can find it +* Set `FLAGS.model_dir` to a Google Cloud Storage bucket url (`gs://`). + + +## Optimizer + +When training on a cloud TPU you **must** wrap the optimizer in a +@{tf.contrib.tpu.CrossShardOptimizer}, which uses an `allreduce` to aggregate +gradients and broadcast the result to each shard (each TPU core). + +The `CrossShardOptimizer` is not compatible with local training. So, to have +the same code run both locally and on a Cloud TPU, add lines like the following: + +``` python +optimizer = tf.train.GradientDescentOptimizer(learning_rate=learning_rate) +if FLAGS.use_tpu: + optimizer = tf.contrib.tpu.CrossShardOptimizer(optimizer) +``` + +If you prefer to avoid a global `FLAGS` variable in your model code, one +approach is to set the optimizer as one of the `Estimator`'s params, +as follows: + +``` python +my_tpu_estimator = tf.contrib.tpu.TPUEstimator( + model_fn=my_model_fn, + config = my_tpu_run_config, + use_tpu=FLAGS.use_tpu, + params={'optimizer':optimizer}) +``` + +## Model Function + +This section details the changes you must make to the model function +(`model_fn()`) to make it `TPUEstimator` compatible. + +### Static shapes + +During regular usage TensorFlow attempts to determine the shapes of each +`tf.Tensor` during graph construction. During execution any unknown shape +dimensions are determined dynamically, +see @{$programmers_guide/tensors#shape$Tensor Shapes} for more details. + +To run on Cloud TPUs TensorFlow models are compiled using @{$xla$XLA}. +XLA uses a similar system for determining shapes at compile time. XLA requires +that all tensor dimensions be statically defined at compile time. All shapes +must evaluate to a constant, and not depend on external data, or stateful +operations like variables or a random number generator. + + +### Summaries + +Remove any use of `tf.summary` from your model. + +@{$summaries_and_tensorboard$TensorBoard summaries} are a great way see inside +your model. A minimal set of basic summaries are automatically recorded by the +`TPUEstimator`, to `event` files in the `model_dir`. Custom summaries, however, +are currently unsupported when training on a Cloud TPU. So while the +`TPUEstimator` will still run locally with summaries, it will fail if used on a +TPU. + +### Metrics + +Build your evaluation metrics dictionary in a stand-alone `metric_fn`. + + + +Evaluation metrics are an essential part of training a model. These are fully +supported on Cloud TPUs, but with a slightly different syntax. + +A standard @{tf.metrics} returns two tensors. The first returns the running +average of the metric value, while the second updates the running average and +returns the value for this batch: + +``` +running_average, current_batch = tf.metrics.accuracy(labels, predictions) +``` + +In a standard `Estimator` you create a dictionary of these pairs, and return it +as part of the `EstimatorSpec`. + +```python +my_metrics = {'accuracy': tf.metrics.accuracy(labels, predictions)} + +return tf.estimator.EstimatorSpec( + ... + eval_metric_ops=my_metrics +) +``` + +In a `TPUEstimator` you instead pass a function (which returns a metrics +dictionary) and a list of argument tensors, as shown below: + +```python +def my_metric_fn(labels, predictions): + return {'accuracy': tf.metrics.accuracy(labels, predictions)} + +return tf.contrib.tpu.TPUEstimatorSpec( + ... + eval_metrics=(my_metric_fn, [labels, predictions]) +) +``` + +### Use `TPUEstimatorSpec` + +`TPUEstimatorSpec` do not support hooks, and require function wrappers for +some fields. + +An `Estimator`'s `model_fn` must return an `EstimatorSpec`. An `EstimatorSpec` +is a simple structure of named fields containing all the `tf.Tensors` of the +model that the `Estimator` may need to interact with. + +`TPUEstimators` use a @{tf.contrib.tpu.TPUEstimatorSpec}. There are a few +differences between it and a standard @{tf.estimator.EstimatorSpec}: + + +* The `eval_metric_ops` must be wrapped into a `metrics_fn`, this field is + renamed `eval_metrics` ([see above](#metrics)). +* The @{tf.train.SessionRunHook$hooks} are unsupported, so these fields are + omitted. +* The @{tf.train.Scaffold$`scaffold`}, if used, must also be wrapped in a + function. This field is renamed to `scaffold_fn`. + +`Scaffold` and `Hooks` are for advanced usage, and can typically be omitted. + +## Input functions + +Input functions work mainly unchanged as they run on the host computer, not the +Cloud TPU itself. This section explains the two necessary adjustments. + +### Params argument + + + +The `input_fn` for a standard `Estimator` _can_ include a +`params` argument; the `input_fn` for a `TPUEstimator` *must* include a +`params` argument. This is necessary to allow the estimator to set the batch +size for each replica of the input stream. So the minimum signature for an +`input_fn` for a `TPUEstimator` is: + +``` +def my_input_fn(params): + pass +``` + +Where `params['batch-size']` will contain the batch size. + +### Static shapes and batch size + +The input pipeline generated by your `input_fn` is run on CPU. So it is mostly +free strict static shape requirements imposed by the XLA/TPU environment. The +one requirement is that the batches of data fed from your input pipeline to +the TPU have a static shape, as determined by the standard TensorFlow shape +inference algorithm. Intermediate tensors are free to have a dynamic shapes. +If shape inference has failed, but the shape is known it is possible to +impose the correct shape using `tf.set_shape()`. + +In the example below the shape +inference algorithm fails, but it is corrected using `set_shape`: + +``` +>>> x = tf.zeros(tf.constant([1,2,3])+1) +>>> x.shape + +TensorShape([Dimension(None), Dimension(None), Dimension(None)]) + +>>> x.set_shape([2,3,4]) +``` + +In many cases the batch size is the only unknown dimension. + +A typical input pipeline, using `tf.data`, will usually produce batches of a +fixed size. The last batch of a finite `Dataset`, however, is typically smaller, +containing just the remaining elements. Since a `Dataset` does not know its own +length or finiteness, the standard @{tf.data.Dataset.batch$`batch`} method +cannot determine if all batches will have a fixed size batch on its own: + +``` +>>> params = {'batch_size':32} +>>> ds = tf.data.Dataset.from_tensors([0, 1, 2]) +>>> ds = ds.repeat().batch(params['batch-size']) +>>> ds + + +``` + +The most straightforward fix is to +@{tf.data.Dataset.apply$apply} @{tf.contrib.data.batch_and_drop_remainder} +as follows: + +``` +>>> params = {'batch_size':32} +>>> ds = tf.data.Dataset.from_tensors([0, 1, 2]) +>>> ds = ds.repeat().apply( +... tf.contrib.data.batch_and_drop_remainder(params['batch-size'])) +>>> ds + + <_RestructuredDataset shapes: (32, 3), types: tf.int32> +``` + +The one downside to this approach is that, as the name implies, this batching +method throws out any fractional batch at the end of the dataset. This is fine +for an infinitely repeating dataset being used for training, but could be a +problem if you want to train for an exact number of epochs. + +To do an exact 1-epoch of _evaluation_ you can work around this by manually +padding the length of the batches, and setting the padding entries to have zero +weight when creating your `tf.metrics`. + +## Datasets + +Efficient use of the `tf.data.Dataset` API is critical when using a Cloud +TPU, as it is impossible to use the Cloud TPU's unless you can feed it data +quickly enough. See @{$datasets_performance} for details on dataset performance. + +For all but the simplest experimentation (using +@{tf.data.Dataset.from_tensor_slices} or other in-graph data) you will need to +store all data files read by the `TPUEstimator`'s `Dataset` in Google Cloud +Storage Buckets. + + + +For most use-cases, we recommend converting your data into `TFRecord` +format and using a @{tf.data.TFRecordDataset} to read it.

Each descendant will implement a different strategy + for distributing the algorithm across multiple devices/machines. + Furthermore, these changes can be hidden inside the specific layers + and other library classes that need special treatment to run in a + distributed setting, so that most users' model definition code can + run unchanged. The `DistributionStrategy` API works the same way + with eager and graph execution. + + First let's introduce a few high-level concepts: + + * _Data parallelism_ is where we run multiple copies of the model + on different slices of the input data. This is in contrast to + _model parallelism_ where we divide up a single copy of a model + across multiple devices. + Note: for now we only support data parallelism at this time, but + hope to add support for model parallelism in the future. + * A _tower_ is one copy of the model, running on one slice of the + input data. + * _Synchronous_, or more commonly _sync_, training is when the + updates from each tower are aggregated together before updating + the model variables. This is in contrast to _asynchronous_, or + _async_ training where each tower updates the model variables + independently. + * Furthermore you might run your computation on multiple devices + on one machine (or "host"), or on multiple machines/hosts. + If you are running on multiple machines, you might have a + single master host that drives computation across all of them, + or you might have multiple clients driving the computation + asynchronously. + + To distribute an algorithm, we might use some of these ingredients: + + * Parameter servers: These are hosts that hold a single copy of + parameters/variables. All towers that want to operate on a variable + retrieve it at the beginning of a step and send an update to be + applied at the end of the step. Can support either sync or async + training. + * Mirrored variables: These are variables that are copied to multiple + devices, where we keep the copies in sync by applying the same + updates to every copy. Normally would only be used with sync training. + * Reductions and Allreduce: A _reduction_ is some method of + aggregating multiple values into one value, like "sum" or + "mean". If doing sync training, we will perform a reduction on the + gradients to a parameter from each tower before applying the + update. Allreduce is an algorithm for performing a reduction on + values from multiple devices and making the result available on + all of those devices. + * TODO(josh11b): Future: partitioned variables + + We have then a few approaches we want to support: + * Code written (as if) with no knowledge of class `DistributionStrategy`. + This code should work as before, even if some of the layers, etc. + used by that code are written to be distribution-aware. This is done + by having a default `DistributionStrategy` that gives ordinary behavior, + and by default being in a single tower context. + * Ordinary model code that you want to run using a specific + `DistributionStrategy`. This can be as simple as: + + ``` + with my_distribution.scope(): + iterator = my_distribution.distribute_dataset(dataset) + # TODO(josh11b): iterator = dataset.make_one_shot_iterator() + tower_train_ops = my_distribution.call_for_each_tower( + tower_fn, iterator.get_next()) + train_op = tf.group(my_distribution.unwrap(tower_train_ops)) + ``` + + This takes an ordinary `dataset` and `tower_fn` and runs it + distributed using a particular `DistributionStrategy` in + `my_distribution`. Any variables created in `tower_fn` are created + using `my_distribution`'s policy, and library functions called by + `tower_fn` can use the `get_tower_context()` API to get enhanced + behavior in this case. + * If you want to write a distributed algorithm, you may use any of + the `DistributionStrategy` APIs inside a + `with my_distribution.scope():` block of code. + + Lower-level concepts: + + * Wrapped values: In order to represent values parallel across devices + (either towers or the devices associated with a particular value), we + wrap them in a "PerDevice" or "Mirrored" object that contains a map + from device to values. "PerDevice" is used when the value may be + different across devices, and "Mirrored" when the value are the same. + * Unwrapping and merging: Consider calling a function `fn` on + multiple devices, like `call_for_each_tower(fn, w)` with an + argument `w that is a wrapped value. This means `w` will have a + map taking tower device `d0` to `w0`, tower device `d1` to `w1`, + etc. `call_for_each_tower()` unwraps `w` before calling `fn`, so + it calls `fn(w0)` on `d0`, `fn(w1)` on `d1`, etc. It then merges + the return values from `fn()`, which can possibly result in + wrapped values. For example, let's say `fn()` returns a tuple with + three components: (x, a, v0) from tower 0, (x, b, v1) on tower 1, + etc. If the first component is the same object `x` from every + tower, then the first component of the merged result will also be + `x`. If the second component is different (`a`, `b`, ...) from + each tower, then the merged value will have a wrapped map from + tower device to the different values. If the third component is + the members of a mirrored variable (`v` maps `d0` to `v0, `d1` to + `v1`, etc.), then the merged result will be that mirrored variable + (`v`). + * Tower context vs. Cross-tower context: _tower context_ is when we + are in some function that is being called once for each tower. + Otherwise we are in cross-tower context, which is useful for + calling `DistributionStrategy` methods which operate across the + towers (like `reduce()`). By default you start in a tower context + (the default "single tower context") and then some methods can + switch you back and forth, as described below. + * Worker devices vs. parameter devices: Most tower computations will + happen on worker devices. Since we don't yet support model + parallelism, there will be one worker device per tower. When using + parameter servers (see above), the set of devices holding + variables may be different, otherwise the parameter devices might + match the worker devices. + * Non-slot devices are some subset of the parameter devices where we + put all the non-slot variables. We need to ensure that all + non-slot variables are allocated on the same device, or mirrored + across the same set of devices. If you have some variable you want + to colocate all the non-slot variables with, you can use + `colocate_vars_with()` to get the remaining non-slot variables on + the same device. Otherwise you can use `non_slot_devices()` to + pick a consistent set of devices to pass to both + `colocate_vars_with()` and `update_non_slot()`. + + When using a `DistributionStrategy`, we have a new type dimension + called _locality_ that says what values are compatible with which + APIs: + + * T: different value for each tower (e.g. a PerDevice-wrapped value). + * M: value is "mirrored" across towers, i.e. there are copies with the + same value on each tower (e.g. a Mirrored-wrapped value). + * V(`v`): value is "mirrored" across all the devices which have a + copy of variable `v` (also a Mirrored-wrapped value, but over + parameter devices instead of worker devices). + * N: value is "mirrored" across all the "non-slot" devices + + Rules for methods with respect to locality and single-tower vs. + cross-tower context: + + * `with d.scope()`: default single-tower context -> cross-tower context for + `d` + * `with d.colocate_vars_with(v)`: in tower/cross-tower context, variables + will be created with locality V(`v`). That is, if we write + `with d.colocate_vars_with(v1): v2 = tf.get_variable(...)`, then + `v2` will have locality V(`v1`), i.e. locality V(`v2`) will equal + V(`v1`). + * `with d.colocate_vars_with(d.non_slot_devices(...))`: in + tower/cross-tower context, variables will be created with locality N + * `v = tf.get_variable(...)`: in tower/cross-tower context, creates + a variable (which by definition will have locality V(`v`), though + will match another locality if inside a `colocate_vars_with` + scope). + * `d.distribute_dataset(dataset)`: in cross-tower context, produces an + iterator with locality T + * `d.broadcast(t)`: in cross-tower context, produces a value with locality M + * `d.broadcast(t, v)`: in cross-tower context, produces a value with + locality V(`v`) + * `d.call_for_each_tower(fn, ...)`: in cross-tower context, runs + `fn()` in a tower context (and so may call `get_tower_context()` and + use its API, including `merge_call()` to get back to cross-tower + context), once for each tower. May use values with locality T or + M, and any variable. + * `d.reduce(m, t)`: in cross-tower context, accepts t with locality T + and produces a value with locality M. + * `d.reduce(m, t, v)`: in cross-tower context, accepts t with + locality T and produces a value with locality V(`v`). + * `d.batch_reduce(m, [(t, v)]): see `d.reduce()` + * `d.update(v, fn, ...)`: in cross-tower context, runs `fn()` once + for each device `v` is copied to, all inputs should have locality + V(`v`), output will have locality V(`v`) as well. + * `d.update_non_slot(d.non_slot_devices(), fn)`: in cross-tower + context, like `d.update()` except with locality N. + * `d.fetch(t)`: Copy `t` with any locality to the client's CPU device. + + The standard pattern for updating variables is to: + + 1. Wrap your input dataset in `d.distribute_dataset()`. + 2. Define each tower `d.call_for_each_tower()` up to the point of + getting a list of gradient, variable pairs. + 3. Call `d.reduce("sum", t, v)` or `d.batch_reduce()` to sum the + gradients (with locality T) into values with locality V(`v`). + 4. Call `d.update(v)` for each variable to update its value. + + Steps 3 and 4 are done automatically by class `Optimizer` if you call + its `apply_gradients` method in a tower context.
