Changed includes of "NvInfer.h" to "tensorrt/include/NvInfer.h" 2. Remove build target "tensorrt_ops.so" (src file doesn't exist and the target is not used anywhere) 3. Add missing '#if GOOGLE_TENSORRT's 4. Use tf_cuda_library instead of cc_library for some targets to get the tf_copts naturally. 5. Revert the changes that was accidentally made (by merging with upstream head) from configure.py 6. Replace exception with LOG(FATAL) in tensorflow/contrib/tensorrt/convert/convert_nodes.cc as exception is not supported. 7.

See [1], [2]. + + Some guidelines: + + * The initial state of the chains should be drawn from a distribution + overdispersed with respect to the target. + * If all chains converge to the target, then as `N --> infinity`, R-hat --> 1. + Before that, R-hat > 1 (except in pathological cases, e.g. if the chain + paths were identical). + * The above holds for any number of chains `C > 1`. Increasing `C` does + improves effectiveness of the diagnostic. + * Sometimes, R-hat < 1.2 is used to indicate approximate convergence, but of + course this is problem depedendent. See [2]. + * R-hat only measures non-convergence of the mean. If higher moments, or other + statistics are desired, a different diagnostic should be used.

Then, in the limit + `N, C --> infinity`, with `E`, `Var` denoting expectation and variance, + + ```R-hat = ( E[Var[X | chain]] + Var[E[X | chain]] ) / E[Var[X | chain]].``` + + Using the law of total variance, the numerator is the variance of the combined + states, and the denominator is the total variance minus the variance of the + the individual chain means.

This information can be used within a distributed implementation when deciding how to route data transfers that might involve more than one hop. By default the new fields are populated according to StreamExecutor::CanEnablePeerAccessTo(), however a platform-specific implementation can augment them with more detailed values.

The main impetus for this change is that I'm about to add LLVM IR implementations of Exp and Log, and those are going to use VectorSupportLibrary. I did not want to have an inconsistency between the tanh and exp, log.

Also, it adapts and unifies the corresponding tests of all unsorted reductions. Note: The new gradient of unsorted_segment_max fixes the crash occuring when negative indices on CPU are used. * update golden API * Fix compilation of atomicAdd for cuda_arch < 600. \n This commit moves the std::complex specialization of atomicAdd below the double specialization of atomicAdd for cuda_arch 600. * Enable bfloat16, change inline to EIGEN_STRONG_INLINE. * fix includes of cuda_device_functions; fix typo --- .../base_api/api_def_UnsortedSegmentMax.pbtxt | 13 +- .../base_api/api_def_UnsortedSegmentMin.pbtxt | 33 ++ .../api_def_UnsortedSegmentProd.pbtxt | 32 ++ tensorflow/core/framework/numeric_types.h | 40 ++- tensorflow/core/kernels/cwise_op_maximum.cc | 4 +- tensorflow/core/kernels/reshape_op.cc | 1 - .../core/kernels/segment_reduction_ops.cc | 305 +++++++++++------- .../core/kernels/segment_reduction_ops.h | 116 ++++--- .../kernels/segment_reduction_ops_gpu.cu.cc | 138 ++++---- tensorflow/core/ops/math_ops.cc | 20 ++ tensorflow/core/util/cuda_device_functions.h | 143 +++++++- tensorflow/core/util/cuda_kernel_helper.h | 54 ---- tensorflow/python/eager/backprop.py | 2 + .../segment_reduction_ops_test.py | 165 ++++++---- tensorflow/python/ops/math_grad.py | 136 ++++++-- tensorflow/python/ops/math_ops.py | 84 +++++ tensorflow/tools/api/golden/tensorflow.pbtxt | 12 + 17 files changed, 900 insertions(+), 398 deletions(-) create mode 100644 tensorflow/core/api_def/base_api/api_def_UnsortedSegmentMin.pbtxt create mode 100644 tensorflow/core/api_def/base_api/api_def_UnsortedSegmentProd.pbtxt diff --git a/tensorflow/core/api_def/base_api/api_def_UnsortedSegmentMax.pbtxt b/tensorflow/core/api_def/base_api/api_def_UnsortedSegmentMax.pbtxt index 8298d62f25..c6b22be30c 100644 --- a/tensorflow/core/api_def/base_api/api_def_UnsortedSegmentMax.pbtxt +++ b/tensorflow/core/api_def/base_api/api_def_UnsortedSegmentMax.pbtxt @@ -14,20 +14,21 @@ Has same shape as data, except for dimension 0 which has size `num_segments`.

Slot variables are created with their checkpointed values as soon as the variable they're slotting for is restored, so there's no need to override slot creation (optimizers already check for existing slot variables before creating a new one). Changes the behavior of unnamed Checkpointable dependencies so that only other unnamed dependencies can interfere (named dependencies do not get a number). This should be a bit more robust, and will support property assignment syntax sugar in a future CL. It does mean that removing a name from a dependency will break the checkpoint (just like changing its name would). One minor fix for slot creation eager compatibility.

This enables the use of the `DatasetOpKernel` subclasses in custom op library code. A subsequent change will move `tf.contrib.data` kernel implementations to a custom op library. Implementation note: This change moves some classes from "tensorflow/core/graph/..." into the framework library, which does not include any code in "tensorflow/core/common_runtime/...". To break the dependency from "tensorflow/core/framework/dataset.cc" to "tensorflow/core/common_runtime/...", the `GraphDefBuilderToGraph()` method has been split out from the `GraphDefBuilder` class (where it was previously exposed as the `GraphDefBuilder::ToGraph()` utility method) and added to a new "tensorflow/core/graph/graph_def_builder_util.h" module. This method depends on ".../graph/graph_constructor.cc", which depends directly on ".../common_runtime/shape_refiner.h" and indirectly on ".../common_runtime/graph_runner.h". Since this method was used only in tests, these have been updated to point to the new utility method.

The sending of protocol messages (**RDMA_MESSAGE_TENSOR_REQUEST**, **RDMA_MESSAGE_META_DATA_RESPONSE** and **RDMA_MESSAGE_TENSOR_RE_REQUEST**) is done by the class **RdmaMessageBuffer**. All messages are sent using RDMA writes from/to fixed messages buffers. This implies that we cannot send on a specific channel more than one message at a time. In order to synchronize the messages, the **RdmaMessageBuffer** holds the a local and remote buffer statuses which can be either busy or idle. When a write is issued, both statuses will be changed to busy. When the write-complete event is received, the local status is changed to idle. When the write is received on the remote side, the remote side will parse the message, and return an ACK back to the sending side on which the sending side will update the remote status to idle. When both the local and remote statuses are idle, the next message can be sent. @@ -115,7 +115,7 @@ When the receiver receives the RDMA write, it will locate the relevant **RdmaTen * Reallocate the result tensor (and proxy tensor if required). * Re-send the request to the remote side. * **RecvTensorContent()** - Receive tensor content from the remote side (RDMA write was completed). - * Decode proto if required and/or move to GPU if the content was not written to it directly (GPU direct is not avaliable). + * Decode proto if required and/or move to GPU if the content was not written to it directly (GPU direct is not available). * Invoke the done callback. * **class RdmaTensorResponse** - Holds and manages information for a single tensor response throughout the entire send cycle.

Signed-off-by: Yong Tang * Adjust shape to pass the test. Signed-off-by: Yong Tang * Improve shape function of SampleDistortedBoundingBox and fix some test cases This fix tries to improve the shape function of SampleDistortedBoundingBox and fix several test case issues. As is shown in the kernel of SampleDistortedBoundingBox, the shape of SampleDistortedBoundingBox are required to be 1-D `[height, width, channels]` for image_size, 3-D with shape `[batch, N, 4]` for bounding_boxes. In the test case, the uses shape is incorrect but becasue of no check in shape function, the test case passes. This fix adds the shape check for SampleDistortedBoundingBox, and fixes the incorrect test cases.

This does the conversion of dense labels into sparse ones to be passed into the core ctc_loss function. * Removed constant_op from the import. * Matched ctc_loss_dense_labels with the other layers ops. * Added ctc_loss_dense_labels to contrib.layers __init__.py file * Added missing comma to list of ops. * Reordred arguments for ctc_loss_dense_labels Labels should be first then inputs for ctc_loss. * Removed ctc_loss_dense_labels. Replaced it with dense_to_sparse instead so that there'll be only one ctc_loss function. * Replaced ctc_loss_dense_labels with dense_to_sparse * Fixed dense_to_sparse. Some of the names of the variables did not match with that of the parameters. * Updated documentation for dense_to_sparse since it can accept a tensor of any shape. * Added test case for dense_to_sparse. * Updated documentation. Dense to sparse accepts int tensors. * Fixed testDenseFromConstantToSparse. The sparse_to_dense order of arguments in the test are wrong and the expected constant should be of int64. * Modified implementation of ndlstm_base_dynamic. It now uses a BasicLSTMCell that has state_is_tuple=True to address deprecation. Right now it is still unknown why it was set to false in the first place. * Imported lstm1d and lstm2d in ndlstm __init__.py. Makes importing ndlstm modules easier. * Added testGetBlocks in lstm2d_test. * Removed testGetBlocks.py * Modified lstm1d.ndlstm_base_unrolled to use lstm_cell with state_is_tuple = True. * Copied some lstm2d.py functions in ndlstm module to contrib.layers. * Update lstm1d.py Reverted changes made. * Update layers_test.py Fixed failing test. * Modified layers.py and layers_test.py.

Instead of keeping track of dependencies manually, we rely on the TF graph structure to find dependencies. The resulting implementation is cleaner and more robust. This does not change any existing behavior. It extends the current behavior by allowing `get_updates_for(inputs)` and `get_losses_for(inputs)` to be called from *any* tensors upstream of the layer, not just the immediate layer's inputs.

Summary of changes: 1. Set MarkForCompilationPassFlags::tf_xla_cpu_global_jit default to true in C_API unit test env when XLA-execute is intended. Together with setting session config config.graph_options.optimizer_options.global_jit_level to > 0, this turns on XLA for the entire graph (eligible nodes only, with _Arg and _RetVal nodes excluded). We decided against defaulting MarkForCompilationPassFlags::tf_xla_cpu_global_jit to true, due to performance concerns with the single-threaded nature of the XLA CPU backend (see https://www.tensorflow.org/performance/xla/jit#turning_on_jit_compilation). 2. In FindCompilationCandidates() during MarkForCompilationPass, skip compiling any '_Arg'-typed nodes. This is necessary to avoid hitting a "Invalid argument number" error during MarkForCompilationPass. 3. Extended C API based build rules to link in XLA libraries, and added unit test "CAPI.Session_Min_XLA_CPU". Also added some misc improvements and debugging aids.

Passing a name with a trailing '/' to import_graph_def causes that name to be used as-is (i.e. it is not appended to the existing name scope and not de-duped with any existing name scopes. This is in order to re-use an existing name scope). This didn't work with the C API enabled because it was set to always have the C API uniquify the prefix. The fix is to not uniquify the prefix, since calling name_scope in import_graph_def already has the logic to uniquify the prefix if necessary. I'm not sure why I thought we needed the C API to do this to being with. In addition, this changes the graph_constructor.cc logic to uniquify names if the prefix cannot be guaranteed unique (see the new test case in graph_constructor_test.cc for why/when this is necessary).

The convolution algorithms returned from the stream executor have a flag for whether tensor_ops is enabled. This flag is used when running each algorithm during auto-tunning. However, this flag is not currently represented in the CustomCall representing the auto-tune result. As a result, the algorithm may be run differently after auto-tune. This change adds a constant to the CustomCall for cudnn convolution algorithm selected by auto-tune, to represent whether tensor_ops is enabled during auto-tune. This information is used by convolution thunk to ensure that the algorithm is run with the same flag after auto-tune.

This reduces the duration during which these constants are semantically represented as floats on the host side and are subject to fast-math-like behavior. This is especially important in cases where the exact bit representation of the floating point constant is significant, but also makes progress towards ensuring that e.g. build XLA with -ffast-math does not change the IR we generate.

} -- GitLab From 7575f334ee0879825ceed23928f5e99d0f71b5f8 Mon Sep 17 00:00:00 2001 From: Justin Lebar Date: Tue, 13 Feb 2018 17:16:29 -0800 Subject: [PATCH 0479/1418] [XLA:GPU] Don't crash when the root instruction of a computation is a multi-output fusion node, and avoid some pointer chasing with tuples. Previously, the kernels we generated would have one argument per *top-level* buffer of the input/output. This was fine for inputs. But it doesn't work for outputs: Imagine you're a node that returns a tuple -- e.g. multi-output fusion -- if all you get is a pointer to the top-level buffer of your output (which should contain pointers to the lower-level buffers at some point, but at the moment is just empty), how are you supposed to figure out where to write your output? (This usually worked because most of the time your output would live inside of the big XLA temp buffer, and kernels always get a pointer to that.) Now we pass all the buffers, top-level and otherwise, to our kernel. In addition, we're now willing to dereference statically tuples that live entirely in XLA's temp buffer. Pointers in input tuples must still be dereferenced dynamically, because the caller has the option of giving us these values or not when invoking XLA. This change makes some parts of BufferAssignment/BufferAllocations more truthful. Previously, if you passed a tuple-shaped input to XLA, we'd say in BufferAllocations that the pointer for some subshape of the param was the *top-level tuple pointer*. XLA then knew that this was a lie and would dereference it accordingly. Now we have an explicit notion of a BufferAllocation pointing to a subshape of an input parameter.

No public methods are exposed, and I've attempted to not throw any errors on __setattr__. Allows dynamic dependencies (track after restore) and restoring variables on assignment to a Checkpointable object, and includes the protocol buffer modifications necessary for saving information with each object. There are still some prominent TODOs: - Stop modifying the graph after the first save/restore (likely cache ops in Checkpointable objects) - Add some overridable methods for saving Python strings when restore() is called, fed when graph building rather than embedded as constants in the graph - Work on the initialization story for graph building. Currently the unit tests rely on collections for this. - Support for more objects, move the prototype modifications in checkpointable_test to core. The diff is larger than I was hoping (mostly deletions and unit tests); that could be reduced a bit (or at least "lines added" converted to "lines deleted") by diffbasing on cl/180950921, which was my first attempt at dynamic dependencies. This CL is more of a re-write than a modification, so sending that one out seems a bit silly. The unit tests are still good, though.

Notice: unlike many NEON paths that we have in this optimized_ops.h file, which are enabled also on x86 by means of arm_neon_sse.h (#ifdef USE_NEON), this one is only enabled on real NEON (#ifdef GEMMLOWP_NEON). The reason for that is that gemmlowp's FixedPoint class is templatized in the underlying raw integer/register type, e.g. here int16x8_t, and on SSE there is only a single __m128i type for all integer types (both int16x8_t and int32x4_t), making it non-trivial to support this on SSE without contriving this code on NEON.

This index is + composed of the values in `Out` at dimensions `output_window_dims`, embedded + with zeroes according to `elided_window_dims`. + +The _window index_ is the relative index of the element in _operand slice_ that +should be present in the output at index `Out`. + +The output is a tensor of rank `output_window_dims.size` + `gather_indices.rank` +- `1`. 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`} + +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` (i.e. pick + `gather_indices.shape.dims[k]`). + 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`[`G`, `i`]. + 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 + +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 -- GitLab From 9739b75fe965ad497b37d209e6a33965010bdc61 Mon Sep 17 00:00:00 2001 From: Alexandre Passos Date: Fri, 16 Feb 2018 15:30:46 -0800 Subject: [PATCH 0636/1418] Default eager tensor device name should match default device name.

This is a prerequisite to moving toward a Saver-like model when graph building. We no longer mess with initializers (when graph building; eager needs it), and restore ops just get queued up and returned. Since initializers are left alone when graph building, there is a new special case for slot variables which needs to be handled. This is the third(!) queue for deferred slot restorations ((1) variable -> slot, (2) optimizer -> slot, (3) (optimizer, variable) -> slot), and should be the last one I need (it's a hypergraph with 3-tuple edges). The plan after this is to switch over to tf.train.Saver's existing restore op creation infrastructure, which will handle any SaveableObjects. There will also be a few CLs for making graph usage prettier, and eventually allowing eager/graph agnostic save/restore.

This change introduces a new C++ Dataset implementation (`GeneratorDataset`) that takes three functions: 1. An initialization function that is called before the first use. 2. A "get next" function that is called to produce the elements, until a call raises the OutOfRange error. 3. A finalization function that is called before the iterator is destroyed. Previously, the generator state would only be cleaned up if the caller consumed *every* element of the generator. In the new version, the finalization function ensures that the Python-side state of the generator is released regardless of how the iterator is disposed. Fixes #16163.

We have renamed metrics_test.MeanTensorTest.testWeighted1d as metrics_test.MeanTensorTest.testBinaryWeighted1d, since the weights on the instances are zeros and ones. We have added a new metrics_test.MeanTensorTest.testWeighted1d that has small weights. It was failing for the previous implementation, but passes now. Now the code for mean_tensor() and mean() now use the same _safe_div method. Previously, mean_tensor() used a different means to ensure that we don't divide by zero. This set the denominator to max(1., sum(weights)), which was inaccurate when sum(weights) is non-zero, but less than one.

I made the following changes: - Moved some tests under a "no layout assignment pass runs" mode. This lets us test the layout specific aspects of the dot operation more thoroughly. Unfortunately not many tests can be run in this mode -- for instance dot tests that calls into Eigen won't work here because they need a specific layout assignment for correctness. Tests that runs with layout assignment enabled but with non-default layouts are essentially integration tests that check that the layout assignment pass + the dot lowering work correctly. - Changed the matrix-vector dot tests to check all 4 layouts and the matrix-vector Ax+b fusion tests to check all 8 layouts. - Duplicated some of the F32 tests to run for F64. - Added some new test shapes.

Without this change, the newly added test would fail with a "Reval[0]" error. This was due to extra Enter nodes being added in the gradients graph in order to enter the outer while contexts for a value that was already in those contexts. The extra Enter nodes would cause the frames of the execution to be messed up, which prevented the final value from being propagated to the outermost Exit node.

The purpose of this feature is to enable experimentation with differentiating the CPU resources available to different stages of a `tf.data` pipeline. As a concrete example, we might use the new feature to move all input-related work from the inter-op threadpool onto a separate threadpool, leaving the inter-op threadpool free to execute higher priority work (such as dispatching ops that send tensors to an accelerator).

The purpose of this change is to make the codebase more maintainable and readable. Before: engine/topology.py models.py After: engine/base_layer.py engine/input_layer.py engine/network.py engine/sequential.py engine/saving.py This is a large change but it only moves code around with no change in logic or API. New files are all under 1000 lines of logic (network.py is 1500 lines, but under 1000 if you remove imports and docstrings), and often under 500.

When `UniqueV2` kernel was added in 12952, it actually supports multi-dimensional and axis support for `unique_with_counts` as well, just not registered. This fix: 1. Register `UniqueWithCountsV2` kernel to have axis support. 2. Hide both `UniqueWithCounts` and `UniqueWithCountsV2` 3. Add python unique_with_counts wrapper to call `gen_array_ops._unique_with_counts` 4. If APi review passes and the PR merges, `unique_with_counts` will switch to `gen_array_ops._unique_with_counts_v2` (in 3 weeks). This fix fixes 16499.

It adds the new proto schemas, enables the behavior for reading and writing the new protos, and adds a test for de/serializing nested while loops.

Agebraic simplification transforms bitcast-equivalent transpose/reshape instructions to bitcast instructions before IR emission. As such, we should skip the checking on whether a transpose/reshape instruction is bitcast-equivalent or not during IR emission. Remove the call from IrArray::Index::SourceIndexOfTranspose to ShapeUtil::TransposeIsBitcast. Also remove the call from IrArray::Index::SourceIndexOfReshape to ShapeUtil::ReshapeIsBitcast. Remove the calls to ShapeUtil::TransposeIsBitcast and ShapeUtil::ReshapeIsBitcast from NotWorthHoistingIndividually because layout assignment hasn't been done there yet. Instead, returns true when the input is a transpose or reshape instruction, to prevent it from being hoisted out of loops. Add a check to ShapeUtil::TransposeIsBitcast and ShapeUtil::ReshapeIsBitcast to make sure that both input shape and output shape have layouts. Add two test cases.

A high-level overview is below. + +## Canned Estimators + +Many canned estimators (subclasses of `Estimator`) have equivalents in core: +`DNNClassifier`, `DNNRegressor`, `DNNEstimator`, `LinearClassifier`, +`LinearRegressor`, `DNNLinearCombinedClassifier` and +`DNNLinearCombinedRegressor`. 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. Dropping this argument is unlikely to + harm your model. + * `feature_engineering_fn`: 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. Instead, use `binary_classification_head` + with a custom `model_fn`, or with `DNNEstimator`. +* `StateSavingRnnEstimator`: Consider a custom `model_fn`. +* SVM: Consider a custom `model_fn`. +* `LinearComposableModel` and `DNNComposableModel`: Not supported. + Consider `tf.contrib.estimator.DNNEstimator`, or write a custom model_fn. +* `MetricSpec`: Deprecated. For adding custom metrics to canned Estimators, use + `tf.contrib.estimator.add_metrics`. + +## Estimator +`tf.contrib.learn.Estimator` is migrated to `tf.estimator.Estimator`. + +To migrate, users need to take the following steps: + +* Replace `tf.contrib.learn.Estimator` with `tf.estimator.Estimator`. +* If you pass a `config` argument to `Estimator`, this must be + `tf.estimator.RunConfig`. You may need to edit your code accordingly. +* Edit your `model_fn` to return `tf.estimator.EstimatorSpec`. Refer to + `EstimatorSpec` for documentation of specific fields. +* If your `model_fn` uses the `mode` argument, use `tf.estimator.ModeKeys`. + +Some related classes: +* `Evaluable`, `Trainable`: Not supported, merged into `tf.estimator.Estimator`. +* ExportStrategy: Replaced by `tf.estimator.Exporter`. + +## Head/MultiHead +These classes are now supported under `tf.contrib.estimator`, e.g. +`tf.contrib.estimator.multi_class_head` and `tf.contrib.estimator.multi_head`. + +Some differences: + +* `multi_class_head`: If you use `tf.contrib.learn.multi_class_head` with + `n_classes=2`, switch to `tf.contrib.estimator.binary_classification_head`. +* `loss_only_head`: Not supported. +* `poisson_regression_head`: Not supported (yet). +* `binary_svm_head`: Not supported (yet). +* `no_op_train_fn`: Replace it with `tf.no_op`. + +Some arguments are renamed, please refer to documentation. In addition: + +* `loss_fn`: Supported for `multi_label_head`. If you need it for other heads, + please open an issue. +* `metric_class_ids`: Not supported (yet). +* `enable_centered_bias`: Not supported. Dropping this argument is unlikely to + harm your model. +* `label_name`: Not needed in `tf.estimator`. If you don’t use `multi_head`, + drop this argument. 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`.

Lavoie Date: Tue, 27 Feb 2018 13:20:03 -0800 Subject: [PATCH 0977/1418] Checkpointable: Move the checkpoint-grouping utility out of the unit test file Renames Saver -> CheckpointableSaver in preparation for exposing the necessary symbols in tf.contrib.eager. There's a pending change for Optimizers, and Asim is handling Layers/Model. Once those are checked in, we should be able to save/restore everything in the eager examples (or at least the mnist one...). Still plenty more to make Checkpointable, but it should be usable at that point.

It adds the new proto schemas, enables the behavior for reading and writing the new protos, and adds a test for de/serializing nested while loops.

Agebraic simplification transforms bitcast-equivalent transpose/reshape instructions to bitcast instructions before IR emission. As such, we should skip the checking on whether a transpose/reshape instruction is bitcast-equivalent or not during IR emission. Remove the call from IrArray::Index::SourceIndexOfTranspose to ShapeUtil::TransposeIsBitcast. Also remove the call from IrArray::Index::SourceIndexOfReshape to ShapeUtil::ReshapeIsBitcast. Remove the calls to ShapeUtil::TransposeIsBitcast and ShapeUtil::ReshapeIsBitcast from NotWorthHoistingIndividually because layout assignment hasn't been done there yet. Instead, returns true when the input is a transpose or reshape instruction, to prevent it from being hoisted out of loops. Add a check to ShapeUtil::TransposeIsBitcast and ShapeUtil::ReshapeIsBitcast to make sure that both input shape and output shape have layouts. Add two test cases.

A high-level overview is below. + +## Canned Estimators + +Many canned estimators (subclasses of `Estimator`) have equivalents in core: +`DNNClassifier`, `DNNRegressor`, `DNNEstimator`, `LinearClassifier`, +`LinearRegressor`, `DNNLinearCombinedClassifier` and +`DNNLinearCombinedRegressor`. 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. Dropping this argument is unlikely to + harm your model. + * `feature_engineering_fn`: 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. Instead, use `binary_classification_head` + with a custom `model_fn`, or with `DNNEstimator`. +* `StateSavingRnnEstimator`: Consider a custom `model_fn`. +* SVM: Consider a custom `model_fn`. +* `LinearComposableModel` and `DNNComposableModel`: Not supported. + Consider `tf.contrib.estimator.DNNEstimator`, or write a custom model_fn. +* `MetricSpec`: Deprecated. For adding custom metrics to canned Estimators, use + `tf.contrib.estimator.add_metrics`. + +## Estimator +`tf.contrib.learn.Estimator` is migrated to `tf.estimator.Estimator`. + +To migrate, users need to take the following steps: + +* Replace `tf.contrib.learn.Estimator` with `tf.estimator.Estimator`. +* If you pass a `config` argument to `Estimator`, this must be + `tf.estimator.RunConfig`. You may need to edit your code accordingly. +* Edit your `model_fn` to return `tf.estimator.EstimatorSpec`. Refer to + `EstimatorSpec` for documentation of specific fields. +* If your `model_fn` uses the `mode` argument, use `tf.estimator.ModeKeys`. + +Some related classes: +* `Evaluable`, `Trainable`: Not supported, merged into `tf.estimator.Estimator`. +* ExportStrategy: Replaced by `tf.estimator.Exporter`. + +## Head/MultiHead +These classes are now supported under `tf.contrib.estimator`, e.g. +`tf.contrib.estimator.multi_class_head` and `tf.contrib.estimator.multi_head`. + +Some differences: + +* `multi_class_head`: If you use `tf.contrib.learn.multi_class_head` with + `n_classes=2`, switch to `tf.contrib.estimator.binary_classification_head`. +* `loss_only_head`: Not supported. +* `poisson_regression_head`: Not supported (yet). +* `binary_svm_head`: Not supported (yet). +* `no_op_train_fn`: Replace it with `tf.no_op`. + +Some arguments are renamed, please refer to documentation. In addition: + +* `loss_fn`: Supported for `multi_label_head`. If you need it for other heads, + please open an issue. +* `metric_class_ids`: Not supported (yet). +* `enable_centered_bias`: Not supported. Dropping this argument is unlikely to + harm your model. +* `label_name`: Not needed in `tf.estimator`. If you don’t use `multi_head`, + drop this argument. 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`.

Previously, the Python integer argument would give a deterministic seeding, and the tf.Tensor argument would give a non-deterministic seeding when the graph seed was not set. This change fixes the behavior so that both versions give the same deterministic seeding. This change also applies the same fix to `tf.contrib.data.shuffle_and_repeat()` and `RandomDataset`.

Extend the stream interface ThenBlasGemmWithAlgorithm to support F16 matrix multiplication with computation type FP32. Extend the stream executor interface DoBlasGemmWithAlgorithm to support F16 GEMM with computation type FP32. Extend the CPU IR emitter to handle F16 Dot instruction, and add F16 matrix multiplication implementation to the CPU runtime. Extend the GPU backend to handle FP16 GEMM Thunk. Replicate the existing matrix multiplication test cases in matrix_ops_simple_test and dot_operation_test for FP16.

This fixes a regression in the defun microbenchmarks (ResNet50Benchmarks.eager_train_with_defun_gpu_batch_32_channels_first etc.) in tensorflow/contrib/eager/python/examples/resnet50/resnet50_test.py seen after https://github.com/tensorflow/tensorflow/commit/9a84277be2cb8233c5c14270db6fcdff31ab4d93 (which embeds a model in model) Without this change, converting a model call to a graph function using something like: model.call = tfe.defun(model.call) could result in redundant nodes being added to the graph function as the model._set_inputs() call would invoke model.call() again.

That meant that accuracy and speed during training -were the top priorities. Using floating point arithmetic was the easiest way to -preserve accuracy, and GPUs were well-equipped to accelerate those calculations, -so it's natural that not much attention was paid to other numerical formats. - -These days, we actually have a lot of models being deployed in commercial -applications. The computation demands of training grow with the number of -researchers, but the cycles needed for inference expand in proportion to users. -That means pure inference efficiency has become a burning issue for a lot of -teams. - -That is where quantization comes in. It's an umbrella term that covers a lot of -different techniques to store numbers and perform calculations on them in more -compact formats than 32-bit floating point. I am going to focus on eight-bit -fixed point, for reasons I'll go into more detail on later. - -[TOC] - -## Why does Quantization Work? - -Training neural networks is done by applying many tiny nudges to the weights, -and these small increments typically need floating point precision to work -(though there are research efforts to use quantized representations here too). - -Taking a pre-trained model and running inference is very different. One of the -magical qualities of deep networks is that they tend to cope very well with high -levels of noise in their inputs. If you think about recognizing an object in a -photo you've just taken, the network has to ignore all the CCD noise, lighting -changes, and other non-essential differences between it and the training -examples it's seen before, and focus on the important similarities instead. This -ability means that they seem to treat low-precision calculations as just another -source of noise, and still produce accurate results even with numerical formats -that hold less information. - -## Why Quantize? - -Neural network models can take up a lot of space on disk, with the original -AlexNet being over 200 MB in float format for example. Almost all of that size -is taken up with the weights for the neural connections, since there are often -many millions of these in a single model. Because they're all slightly different -floating point numbers, simple compression formats like zip don't compress them -well. They are arranged in large layers though, and within each layer the -weights tend to be normally distributed within a certain range, for example -3.0 -to 6.0. - -The simplest motivation for quantization is to shrink file sizes by storing the -min and max for each layer, and then compressing each float value to an -eight-bit integer representing the closest real number in a linear set of 256 -within the range. For example with the -3.0 to 6.0 range, a 0 byte would -represent -3.0, a 255 would stand for 6.0, and 128 would represent about 1.5. -I'll go into the exact calculations later, since there's some subtleties, but -this means you can get the benefit of a file on disk that's shrunk by 75%, and -then convert back to float after loading so that your existing floating-point -code can work without any changes. - -Another reason to quantize is to reduce the computational resources you need to -do the inference calculations, by running them entirely with eight-bit inputs -and outputs. 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). It also opens -the door to a lot of embedded systems that can't run floating point code -efficiently, so it can enable a lot of applications in the IoT world. - -## Why Not Train in Lower Precision Directly? - -There have been some experiments training at lower bit depths, but the results -seem to indicate that you need higher than eight bit to handle the back -propagation and gradients. That makes implementing the training more -complicated, and so starting with inference made sense. We also already have a -lot of float models already that we use and know well, so being able to convert -them directly is very convenient. - -## How Can You Quantize Your Models? - -TensorFlow has production-grade support for eight-bit calculations built in. It -also has a process for converting many models trained in floating-point over to -equivalent graphs using quantized calculations for inference. For example, -here's how you can translate the latest GoogLeNet model into a version that uses -eight-bit computations: - -```sh -curl -L "https://storage.googleapis.com/download.tensorflow.org/models/inception_v3_2016_08_28_frozen.pb.tar.gz" | - tar -C tensorflow/examples/label_image/data -xz -bazel build tensorflow/tools/graph_transforms:transform_graph -bazel-bin/tensorflow/tools/graph_transforms/transform_graph \ - --in_graph=tensorflow/examples/label_image/data/inception_v3_2016_08_28_frozen.pb \ - --out_graph=/tmp/quantized_graph.pb \ - --inputs=input \ - --outputs=InceptionV3/Predictions/Reshape_1 \ - --transforms='add_default_attributes strip_unused_nodes(type=float, shape="1,299,299,3") - remove_nodes(op=Identity, op=CheckNumerics) fold_constants(ignore_errors=true) - fold_batch_norms fold_old_batch_norms quantize_weights quantize_nodes - strip_unused_nodes sort_by_execution_order' +# Fixed Point Quantization + +Quantization techniques store and calculate numbers in more compact formats. +[TensorFlow Lite](/mobile/tflite/) adds quantization that uses an 8-bit fixed +point representation. + +Since a challenge for modern neural networks is optimizing for high accuracy, the +priority has been improving accuracy and speed during training. 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} 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. We also hope that this demonstration will encourage the -community to explore what's possible with low-precision neural networks. +See the documentation for @{tf.contrib.quantize} and +[TensorFlow Lite](/mobile/tflite/). + +## Quantized accuracy + +Fixed point [MobileNet](https://arxiv.org/abs/1704.0486) models are released with +8-bit weights and activations. Using the rewriters, these models achieve the +Top-1 accuracies listed in Table 1. For comparison, the floating point accuracies +are listed for the same models.

Switches subclassed Models to creating ResourceVariables by default, which removes one source of eager/graph differences. tfe.Network was doing this by default. This is necessary for eager/graph agnostic code since tapes currently only work with ResourceVariables. It's not quite trivial to fix that, and ResourceVariables by default in more places is a Good Thing anyway. (Not that we shouldn't also fix the tape code.)

For variables without a more deeply nested Template parent, it adds a dependency directly. For variables with a Template parent, it adds a dependency on the sub-Template instead. The variable scope prefix for the Template itself is stripped. However, any variable_scopes inside the Template (such as those for Layers) will be included in the dependency names. So within Templates we essentially have name-based saving (with the exception of dependencies between Templates themselves, which use the object-based dependency mechanism). This isn't ideal, but will hopefully allow migration toward object oriented dependencies more smoothly. Throws an error on object-based save() if the dependencies don't match between Checkpointable and .variables. Includes a semi-related usability fix for the Checkpoint utility; mostly in unit tests, restore() is not called before save(), which when graph building was leading to the save counter not being initialized. Fixes that.

When a write is issued, both statuses will be changed to busy. When the write-complete event is received, the local status is changed to idle. When the write is received on the remote side, the remote side will parse the message, and return an ACK back to the sending side on which the sending side will update the remote status to idle.

Don't create additional read ops when creating a ResourceVariable from a VariableDef proto. 2. Expose the ability to assign a ResourceVariable without reading & returning the new value. 3. Colocating with a ResourceVariable's ".op" property eliminates the creation of additional read ops. 4. Savers can read a variable's value using the _graph_element property, since these reads don't need control dependencies. This makes the visualization of graphs on TensorBoard much nicer.

Unique TensorFlower" Date: Fri, 2 Mar 2018 11:18:41 -0800 Subject: [PATCH 1181/1418] Add a configurable preference for scheduling fuller batches sooner to the adaptive shared batcher.

This change introduces a new stand-alone function, EvaluateConstantTensor, pulled from ShapeRefiner. ShapeRefiner now calls this new function and the old functions are removed. I'm still depending on shape_refiner_test.cc for test coverage. This is the first step towards making smart_cond better able to evaluate constant tensors.

It may produce incorrect result when mixed precision is not supported and BF16 is not support only for a particular operand. Then the pass may introduce new mixed precision for an all-BF16 CRS. This is unlikely in practical settings, but removing this constraint can enable auto-generating corner case tests using this pass. 2. A cycle can be introduced in the tuple-shaped output output. This wasn't caught by the test because the DFS happened to succeed. Now add verifier explicitly.

Unique TensorFlower" Date: Mon, 5 Mar 2018 17:07:39 -0800 Subject: [PATCH 1268/1418] Improve the accuracy of the upper-bound of the sum of the size of an HLO and all its dependencies. The previous implementation computed the size of an HLO as the sum of dependencies weighted by the number of paths to the each dependency. In the previous implementation the "size" of some HLO overflowed an int64 for dependence graphs with a large number of distinct paths. The new implementation computes the min of the previous overestimate and the sum of all HLO's before-and-including the current HLO in a topological sort of the graph. Both the current and the previous implementations are linear time. Since the sum of the size of all HLOs will never overflow, the "total size" of each HLO will never overflow. The new upper-bound is the min of the previous upper bound and a new heuristic, so it is always at least as tight a bound as the old implementation.

Currently this never happens because we only turn rehaspes into bitcasts after layout assignment. This changes when layout assignment runs before fusion. Once layouts are available the pipeline turns reshapes into bitcasts, which would be left unfused without this change.

Further detail covered by a comment inside pooling_ops.cc. Retains 32 bits of gradient precision, but can confuse the backprop source for input cells that are equally maximal at 16 bits. We could in principle be accurate up to 31 bits of input, if we were willing to find gradients one bit at a time, or 24 bits of input 8 gradient bits at a time, etc. PiperOrigin-RevId: 188025278 --- tensorflow/compiler/tests/pooling_ops_test.py | 133 +++++++++++--- .../tf2xla/g3doc/cpu_supported_ops.md | 14 ++ .../tf2xla/g3doc/gpu_supported_ops.md | 14 ++ .../compiler/tf2xla/kernels/pooling_ops.cc | 167 ++++++++++++++++++ 4 files changed, 305 insertions(+), 23 deletions(-) diff --git a/tensorflow/compiler/tests/pooling_ops_test.py b/tensorflow/compiler/tests/pooling_ops_test.py index e0e85295fe..fe270af3d6 100644 --- a/tensorflow/compiler/tests/pooling_ops_test.py +++ b/tensorflow/compiler/tests/pooling_ops_test.py @@ -292,8 +292,15 @@ class PoolGradTest(XLATestCase): CPU_DEVICE = "/job:localhost/replica:0/task:0/cpu:0" - def _VerifyOneTest(self, pool_func, pool_grad_func, input_sizes, ksize, - strides, padding, data_format): + def _VerifyOneTest(self, + pool_func, + pool_grad_func, + input_sizes, + ksize, + strides, + padding, + data_format, + pool_grad_grad_func=None): """Verifies the output values of the pooling gradient function.

This change makes CondContext._external_values more consistently store Tensors external this context. These values are then not added to the context when it's imported. This also removes the workaround I added earlier to manually remove the predicate and pivot Tensors from the context, instead adding them to _external_values were they're automatically excluded.

The overall approach is to use Graph._lock to synchronize Session.run calls and construction methods that rely on graph mutation. We don't want to synchronize the actual running of the graph, only the Extend call, so this change exposes an ExtendSession method to the Python API and disables extending automatically in TF_SessionRun.

This change avoids the overhead of function dispatch (~10--15us) when the filter predicate simply returns one of its arguments directly. It also adds a benchmark to track the performance of this optimization. The checkpointing code required minor modifications to enable functions to be instantiated in the `FilterDatasetOp::Compute()` method when an iterator is being restored.

Adding tflite_portable_test_suite() to the bottom of a package marks all previous cc_tests as "intended to be portable". I've included all tests that I was able to naively make buildable on Android with my previous change that created a custom logging.h library. Most tests are buildable on Android already, but there is something in the common dependencies for the kernel tests that is not compatible with iOS. Outside of Google, this change does nothing except tag tests that are known to not be buildable on certain platforms.
