Previously ShapedBuffer only held array-shaped data at the leaves of the tuple shape. Construction of these array-of-pointers is handled by TransferManager which has to construct array-of-pointers anyway to transfer literals to the device. This change makes ShapedBuffer match the native representative of tuple-shaped data passed into XLA computations. This is the first step to migrating XLA interfaces away from using naked device memory pointers (DeviceMemoryBase) to using more expressive ShapedBuffers instead. This change enables tuple-shaped parameters in computations run through the LocalClient interface. Also, change LocalClient interfaces to return ScopedShapedBuffers as these are generally easier to deal with ownership-wise that ShapedBuffers. They are analogous to std::unique_ptr, while ShapedBuffers are analogous to bare pointers. This change includes a couple other cleanups found along the way: * move cpu/gpu/interpreter transfer managers into their respective directories under xla/service. * Make the generic transfer manager take a pointer size. Previously it would just use sizeof(void*) which might not be exactly what is needed.

Unique TensorFlower" Date: Tue, 26 Sep 2017 22:55:11 -0700 Subject: [PATCH 0049/1559] Define OpContext and use it for OpLevelCostEstimator. This CL does not add any functionality (except GraphDef's function library pointer is passed to OpContext), but we can later add additional fields to OpContext struct for extending VirtualCluster, Scheduler, Placer, and others.

This supports building the gradient graph as long as the body function of the while loop contains no ops whose gradient function requires a stack. In other words, it doesn't support gradient functions that use the input values to the op (e.g. add will work, but multiply will not). It also doesn't support nested while loops, and doesn't detect all error cases.

The Dataset graph is stored as a serialized GraphDef using a pre-defined key. The name of the output node of this GraphDef is stored in a separate key using the BundleWriter. When restoring the checkpoint, the Dataset graph, if available, is deserialized and executed using the GraphRunner to get the Dataset which is then used to construct the Iterator. Also moved BundleReaderWrapper and BundleWriterWrapper out of IteratorBase so they can be more generally used.

RAUW used to be *almost* synonymous with RUOI, except RAUW didn't update the computation's root. This was a dangerous footgun -- if you accidentally called RAUW when you wanted RUOI (which you almost always did), your code would work perfectly, except when the relevant node happened to be the root of a computation. This change simplifies our APIs so there's just one Right Way To Do It, by making RAUW update the computation.

This is because CondContext.AddOp() is called before creating self._c_op in Operation.__init__(), and AddOp() uses the Operation methods that call the C API. We need to use the original Python-only code before self._c_op has been created. I added a comment in ops.py explaining an alternative to this solution that we may wish to implement later.

END_PUBLIC --- Commit 301b14c24 authored by Skye Wanderman-Milne Committed by TensorFlower Gardener: Basic while loop gradient functionality in C++ This change introduces the basic framework to create the gradient graph of a while loop using the C++ API. This supports building the gradient graph as long as the body function of the while loop contains no ops whose gradient function requires a stack. In other words, it doesn't support gradient functions that use the input values to the op (e.g. add will work, but multiply will not). It also doesn't support nested while loops, and doesn't detect all error cases.

Previously, if no (op- or graph-level) seed was specified, `Dataset.shuffle()` would reshuffle its elements after each iteration (e.g. when passed to `Dataset.repeat()`). When an explicit seed was specified, it would produce the same sequence on each repetition. Since other utilities (such as `Estimator`) may set a graph-level seed without the user's awareness, this can lead to a surprising lack of randomness (and the potential for overfitting). This change adds an optional `reshuffle_each_iteration` argument to `Dataset.shuffle()`, which defaults to `True`. If you desire that multiple repetitions of a `Dataset.shuffle()` produce the same order, set `reshuffle_each_iteration=False`.

Unique TensorFlower" Date: Thu, 28 Sep 2017 11:53:24 -0700 Subject: [PATCH 0138/1559] Adds tf.contrib.nn.scaled_softplus(x, alpha) = alpha * softplus(x/alpha). This can be thought of as a smoothed version of a ReLU. On Imagenet, alpha=0.3 gives 0.6-1% improvement in validation accuracy compared to ReLU, by reducing the generalization gap.

From @rhaertel80: There are cases where it is useful to have externally defined keys and have these keys passed through from the input to the output. As an example, consider a batch prediction service: The service simply runs inference on the users graph and returns the results. Keys are essential because there is no order guarantee on the outputs so they need to be rejoined to the inputs via keys or transclusion of the inputs in the outputs.

This adds new classes to represent each of the possible tensor types, and some scripting support for generating those classes. There is essentially no effect on existing classes, except that DataType is made slightly more efficient. All tests pass. * Addressed Asim's review. * Hoisted copyright into a separate declaration. Maybe it should go in a separate file? * Added private constructors to TF types and shortened their javadoc to be more standard. * Added more explanation about the enum relationship. * Used more-idiomatic import statement. * Rename zero column. * Removed the datatype code from tftypes.csv * Fix the default value for Double, add one for UInt8. * Got rid of 'boxed type' column in CSV file * Somehow I did not notice that TFType.java was not checked in. * Phase 2 : Tensor, Output and friends are now parameterized. * All tests now pass. * Cleaned up and added some Javadoc and made some static fields private. * Made Outputs more convenient to use. Improved Javadoc regarding this functionality. Added explicit type parameters to examples and tests to make them better models of expected practice. * Removed extra copy of method. * This change to the Android demo app should allow it to compile successfully * Backed out unnecessary but presumably harmless removal of calls to clear(). * Change from Unicode times symbol to x, to be more consistent with the rest of the Javadoc. * Updated Constant and ConstantTest with generics. * Registered UInt8 like all the other data types. * Removed the UINT8 test because UINT8 doesn't seem to be fully supported in next layer down. That probably should be fixed but it's orthongonal to this change. * * Added some missing pieces so that uint8 seems now to be supported fully by the Java API, addressing #12797. * Resurrected the uint8 test case. * Allowed arrays of bytes to be used to construct both tensors of strings and tensors of uint8. * Simplified the computation of the number of dimensions of a Java object representing a tensor. * Get rid of tab characters that violate the Google Java style guide. My IDE was not configured correctly. * Fix javadoc nit. * Replace testUInt8 with the generic version. * Ran formatter on code. * Addressed some of Asim's comments. - implemented constant() methods in terms of each other to reduce code duplication - improved a spec regarding when types are checked - got rid of an unnecessary method that used wildcards * Back out change to comments in Operand.java * This is what things look like if we make Tensor run on DataType as much as possible. Only Tensor.expect() is still using class objects as a way to represent tensor datatypes. It can be moved off to class Tensors when Tensors exists, though it will not be as convenient as when it's a method of Tensor. * Fixed build errors. This is is being committed primarily so Asim can take a look at it conveniently. More work will be needed before merging. * - Changed from TF-prefixed types to regular Java classes, e.g. Integer instead of TFInt32. Deleted most classes in org.tensorflow.types, including TFType. - Made Tensor mostly work in terms of Class since that is the user-facing interface. - Moved zeroValue() stuff off to the testfile where it belongs * Remove unnecessary run-time check. * Updated Android inference test to latest Java API changes. * Address Asim's comments (thanks!) - Removed now-gratuitous run-time type-check. - Fixed non-Google-styled if. - Reworded/fixed a few comments as requested. - Removed all uses of unsafe casts and @SuppressWarnings in test cases. - Cleaned up constant() implementations in LabelImage example. - Removed reference to Tensors class (next PR!) * Ran gformat on everything. * Fixed an old typo in a comment. Removed a couple of unnecessary casts from the example program. * Fixed the last suppressed warnings. --- .../android/TensorFlowInferenceInterface.java | 18 +- tensorflow/java/src/gen/perl/tftypes.pl | 14 +- .../main/java/org/tensorflow/DataType.java | 43 +++- .../src/main/java/org/tensorflow/Graph.java | 7 +- .../java/org/tensorflow/NativeLibrary.java | 9 +- .../src/main/java/org/tensorflow/Operand.java | 8 +- .../main/java/org/tensorflow/Operation.java | 18 +- .../java/org/tensorflow/OperationBuilder.java | 14 +- .../src/main/java/org/tensorflow/Output.java | 12 +- .../java/org/tensorflow/SavedModelBundle.java | 5 +- .../src/main/java/org/tensorflow/Session.java | 34 +-- .../src/main/java/org/tensorflow/Tensor.java | 226 ++++++++++++------ .../org/tensorflow/examples/LabelImage.java | 75 ++++-- .../main/java/org/tensorflow/op/Operands.java | 8 +- .../java/org/tensorflow/op/core/Constant.java | 34 +-- .../java/org/tensorflow/types/TFBool.java | 30 --- .../java/org/tensorflow/types/TFDouble.java | 30 --- .../java/org/tensorflow/types/TFFloat.java | 30 --- .../java/org/tensorflow/types/TFInt32.java | 30 --- .../java/org/tensorflow/types/TFInt64.java | 30 --- .../java/org/tensorflow/types/TFString.java | 27 --- .../java/org/tensorflow/types/TFUInt8.java | 30 --- .../main/java/org/tensorflow/types/Types.java | 52 ---- .../types/{TFType.java => UInt8.java} | 9 +- .../org/tensorflow/types/package-info.java | 15 +- .../test/java/org/tensorflow/GraphTest.java | 1 - .../org/tensorflow/OperationBuilderTest.java | 22 +- .../java/org/tensorflow/OperationTest.java | 19 +- .../test/java/org/tensorflow/SessionTest.java | 41 ++-- .../test/java/org/tensorflow/ShapeTest.java | 2 +- .../test/java/org/tensorflow/TensorTest.java | 88 +++---- .../test/java/org/tensorflow/TestUtil.java | 24 +- .../java/org/tensorflow/op/OperandsTest.java | 4 +- .../org/tensorflow/op/PrimitiveOpTest.java | 2 +- .../java/org/tensorflow/op/ScopeTest.java | 127 ++++++---- .../org/tensorflow/op/core/ConstantTest.java | 21 +- 36 files changed, 554 insertions(+), 605 deletions(-) delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFBool.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFDouble.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFFloat.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFInt32.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFInt64.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFString.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/TFUInt8.java delete mode 100644 tensorflow/java/src/main/java/org/tensorflow/types/Types.java rename tensorflow/java/src/main/java/org/tensorflow/types/{TFType.java => UInt8.java} (87%) diff --git a/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java b/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java index 395dd6c5d2..f5710cc7c1 100644 --- a/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java +++ b/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java @@ -31,12 +31,12 @@ import java.nio.IntBuffer; import java.nio.LongBuffer; import java.util.ArrayList; import java.util.List; -import org.tensorflow.DataType; import org.tensorflow.Graph; import org.tensorflow.Operation; import org.tensorflow.Session; import org.tensorflow.Tensor; import org.tensorflow.TensorFlow; +import org.tensorflow.types.UInt8; /** * Wrapper over the TensorFlow API ({@link Graph}, {@link Session}) providing a smaller API surface @@ -328,7 +328,7 @@ public class TensorFlowInferenceInterface { * destination has capacity, the copy is truncated. */ public void feed(String inputName, byte[] src, long... dims) { - addFeed(inputName, Tensor.create(DataType.UINT8, dims, ByteBuffer.wrap(src))); + addFeed(inputName, Tensor.create(UInt8.class, dims, ByteBuffer.wrap(src))); } /** @@ -403,7 +403,7 @@ public class TensorFlowInferenceInterface { * destination has capacity, the copy is truncated. */ public void feed(String inputName, ByteBuffer src, long... dims) { - addFeed(inputName, Tensor.create(DataType.UINT8, dims, src)); + addFeed(inputName, Tensor.create(UInt8.class, dims, src)); } /** @@ -544,7 +544,7 @@ public class TensorFlowInferenceInterface { "Model load took " + (endMs - startMs) + "ms, TensorFlow version: " + TensorFlow.version()); } - private void addFeed(String inputName, Tensor t) { + private void addFeed(String inputName, Tensor t) { // The string format accepted by TensorFlowInferenceInterface is node_name[:output_index].

Like HloComputation::instructions(), HloModule::computations() used to return a list of unique_ptrs. But this is an implementation detail that shouldn't be leaked into the public API. This patch also adds HloModule::MakeNonFusionComputations(), because many of the callers of computations() went on to filter out all the fusion computations. It would be possible to implement MakeNonFusionComputations() "in place" using a filtering iterator, but I don't think it's necessary -- we never have *that* many computations, and since many callers go on to copy the list of non-fusion computations, making it unconditionally a copy is simpler and avoids a footgun.

This way users of the class don't have to remember to capture each one manually to avoid premature deallocation and memory races for asynchronous op kernels. * Add simple tests that run multiple ops concurrently for linalg ops that use CudaSolver. * Put a lock around the calls to cusolverDn*getrs and cusolverDn*gesvd, which appear not to be threadsafe. * Misc. cleanup in linalg GPU kernels. I ran all the related tests 1000 times without failure. Before this change, tests for matrix_solve and svd would fail or hang occasionally.

[kfac-paper]: https://arxiv.org/abs/1503.05671 +## What is K-FAC? + +K-FAC, short for "Kronecker-factored Approximate Curvature", is an approximation +to the [Natural Gradient][natural_gradient] algorithm designed specifically for +neural networks. It maintains a block-diagonal approximation to the [Fisher +Information matrix][fisher_information], whose inverse preconditions the +gradient. + +K-FAC can be used in place of SGD, Adam, and other `Optimizer` implementations. +Experimentally, K-FAC converges `>3.5x` faster than well-tuned SGD. + +Unlike most optimizers, K-FAC exploits structure in the model itself (e.g. "What +are the weights for layer i?"). As such, you must add some additional code while +constructing your model to use K-FAC. + +[natural_gradient]: http://www.mitpressjournals.org/doi/abs/10.1162/089976698300017746 +[fisher_information]: https://en.wikipedia.org/wiki/Fisher_information#Matrix_form + +## Why should I use K-FAC? + +K-FAC can take advantage of the curvature of the optimization problem, resulting +in **faster training**. For an 8-layer Autoencoder, K-FAC converges to the same +loss as SGD with Momentum in 3.8x fewer seconds and 14.7x fewer updates. See how +training loss changes as a function of number of epochs, steps, and seconds: + +![autoencoder](g3doc/autoencoder.png) + +## Is K-FAC for me? + +If you have a feedforward or convolutional model for classification that is +converging too slowly, K-FAC is for you. K-FAC can be used in your model if: + +* Your model defines a posterior distribution. +* Your model uses only fully-connected or convolutional layers (residual + connections OK). +* You are training on CPU or GPU. +* You can modify model code to register layers with K-FAC. + +## How do I use K-FAC? + +Using K-FAC requires three steps: + +1. Registering layer inputs, weights, and pre-activations with a + `LayerCollection`. +1. Minimizing the loss with a `KfacOptimizer`. +1. Keeping K-FAC's preconditioner updated. + +```python +# Build model. +w = tf.get_variable("w", ...) +b = tf.get_variable("b", ...) +logits = tf.matmul(x, w) + b +loss = tf.reduce_mean( +

Unique TensorFlower" Date: Mon, 2 Oct 2017 23:33:20 -0700 Subject: [PATCH 0288/1559] Add XlaCompiledFunction, a lightweight API for calling XLA computations that are compiled down to functions. The API is based on a generic form of the original AOT auto-generated header. For AOT (tfcompile), this API has been slotted into the auto-generated header. For JIT, a new XlaCompiledFunctionJit class has been added, which compiles a tensorflow::GraphDef and allows the user to create XlaCompiledFunction objects. XlaCompiledFunction contains optional metadata; mappings from arg/result names to their index, and the program shape. This data is always available via JIT, but only provided via AOT if the tfcompile --gen_name_to_index and --gen_program_shape flags are set. We don't enable by default for AOT to keep binary sizes smaller; the ProgramShape proto pulls in lots of code, and may also be large.

(#13421) * Java API Generics Phase 3. - Added the utility Tensors class. - Updated tests to use it. - Updated scripts for generating Tensors.java and the types directory. Note that these are still run manually, but remain helpful because maintaining so many methods and their documentation is a headache. - Added missing checking for attempts to create tensors from arrays of boxed primitives, and a test case. * Oops. This is the generated file! * Addressed Asim's comments. - made Tensors final - got rid of unused state in UInt8 objects - tuned up various javadoc comments --- .../android/TensorFlowInferenceInterface.java | 5 +- .../java/src/gen/perl/tftypes-runall.pl | 2 +- tensorflow/java/src/gen/perl/tftypes.pl | 88 +++- .../java/src/gen/resources/Tensors.java.tmpl | 31 ++ tensorflow/java/src/gen/resources/tftypes.csv | 42 +- .../main/java/org/tensorflow/DataType.java | 4 +- .../src/main/java/org/tensorflow/Operand.java | 4 +- .../src/main/java/org/tensorflow/Tensor.java | 39 +- .../src/main/java/org/tensorflow/Tensors.java | 432 ++++++++++++++++++ .../org/tensorflow/examples/LabelImage.java | 8 +- .../org/tensorflow/types/package-info.java | 3 +- .../org/tensorflow/OperationBuilderTest.java | 13 +- .../test/java/org/tensorflow/SessionTest.java | 8 +- .../test/java/org/tensorflow/TensorTest.java | 55 ++- .../java/org/tensorflow/op/OperandsTest.java | 5 +- .../java/org/tensorflow/op/ScopeTest.java | 5 +- 16 files changed, 634 insertions(+), 110 deletions(-) create mode 100644 tensorflow/java/src/gen/resources/Tensors.java.tmpl create mode 100644 tensorflow/java/src/main/java/org/tensorflow/Tensors.java diff --git a/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java b/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java index f928ec73a4..743a12b925 100644 --- a/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java +++ b/tensorflow/contrib/android/java/org/tensorflow/contrib/android/TensorFlowInferenceInterface.java @@ -35,6 +35,7 @@ import org.tensorflow.Graph; import org.tensorflow.Operation; import org.tensorflow.Session; import org.tensorflow.Tensor; +import org.tensorflow.Tensors; import org.tensorflow.TensorFlow; import org.tensorflow.types.UInt8; @@ -337,7 +338,7 @@ public class TensorFlowInferenceInterface { * a Java {@code String} (which is a sequence of characters). */ public void feedString(String inputName, byte[] src) { - addFeed(inputName, Tensor.create(src)); + addFeed(inputName, Tensors.create(src)); } /** @@ -346,7 +347,7 @@ public class TensorFlowInferenceInterface { * arbitrary sequence of bytes, not a Java {@code String} (which is a sequence of characters). */ public void feedString(String inputName, byte[][] src) { - addFeed(inputName, Tensor.create(src)); + addFeed(inputName, Tensors.create(src)); } // Methods for taking a native Tensor and filling it with src from Java native IO buffers. diff --git a/tensorflow/java/src/gen/perl/tftypes-runall.pl b/tensorflow/java/src/gen/perl/tftypes-runall.pl index 258c1ff836..a451ce92aa 100644 --- a/tensorflow/java/src/gen/perl/tftypes-runall.pl +++ b/tensorflow/java/src/gen/perl/tftypes-runall.pl @@ -37,4 +37,4 @@ sub locchk { &locchk("$rsrc/tftypes.csv"); system("perl $dir/tftypes.pl -t $rsrc/tftypes.csv $pkg/types"); -# system("perl $dir/tftypes.pl -c $rsrc/tftypes.csv $rsrc/Tensors.java.tmpl > $pkg/op/Tensors.java"); +system("perl $dir/tftypes.pl -c $rsrc/tftypes.csv $rsrc/Tensors.java.tmpl > $pkg/Tensors.java"); diff --git a/tensorflow/java/src/gen/perl/tftypes.pl b/tensorflow/java/src/gen/perl/tftypes.pl index c812efb536..115723ac8a 100644 --- a/tensorflow/java/src/gen/perl/tftypes.pl +++ b/tensorflow/java/src/gen/perl/tftypes.pl @@ -75,15 +75,23 @@ open (TYPEDESC, $typedesc); my @info = ([]); +sub trim { + (my $ret) = @_; + $ret =~ s/^\s*//g; + $ret =~ s/\s*$//g; + return $ret; +} + while () { chomp; my $line = $_; if ($line =~ m/^TF type/) { next } $line =~ s/\r$//; - (my $name, my $jtype, my $creat, my $default, my $desc) = - split /,/, $line, 5; - $desc =~ s/^ *//g; - $desc =~ s/ *$//g; + my @items = split /,/, $line, 6; + for (my $i = 0; $i <= $#items; $i++) { + $items[$i] = trim $items[$i]; + } + my $jtype = $items[2]; $jtypecount{$jtype}++; if ($jtypecount{$jtype} > 1) { # currently allowing Java types to stand for more than one TF type, but @@ -92,53 +100,85 @@ while () { # exit 1 } - push @info, [$name, $jtype, $creat, $default, $desc]; + push @info, \@items; +} + +sub article { + (my $s) = @_; + if (substr($s, 0, 1) =~ m/^[aeoiu8]$/i) { + return "an $s" + } else { + return "a $s" + } } for (my $i = 1; $i <= $#info; $i++) { - (my $name, my $jtype, my $creat, my $default, my $desc) = + (my $name, my $builtin, my $jtype, my $creat, my $default, my $desc) = @{$info[$i]}; - my $tfname = "TF".$name; + my $tfname = $name; my $ucname = uc $name; + print STDERR "$name $desc\n"; + if ($option eq '-t') { if ($jtype eq '') { next } + if ($builtin eq 'y') { next } # Generate class declarations # print STDERR "Creating $dirname/$tfname.java\n"; open (CLASSFILE, ">$dirname/$tfname.java") || die "Can't open $tfname.java"; - print CLASSFILE $copyright; - print CLASSFILE "// GENERATED FILE.

We will use + `g1` and `g3` to define bijector methods over `D1` and `D3`. `D2 = {0}` is + an oddball in that `g2` is one to one, and the derivative is not well defined. + Fortunately, when considering transformations of probability densities + (e.g. in `TransformedDistribution`), sets of measure zero have no effect in + theory, and only a small effect in 32 or 64 bit precision.

The option was used to generate executables which only generated the array values of tuple-shaped outputs, not the tuple index tables.. With cl/170133015, ShapedBuffers which hold the computation output now have materialized tuples with these index tables so this option is no longer desired or necessary. No functional change. Just cleanup.

After this CL, state space models will first normalize, then use adjusted statistics on top of that normalization to estimate initial observation/transition noise.

Instead of adding the option to respect `is_the_final_export` into the `Exporter` that also does garbage collection, such exporter is split into two: `LatestExporter` and `FinalExporter`. There is a concern that options `exports_to_keep` and `only_the_final_export` overlap significantly and are somewhat in conflict. What does it mean to keep last 5 exports but only export the final one? After splitting in two classes there is a lot of code duplication. The common implementation is gathered in a private base class. When the training ends, the final export is performed via `Exporter.export()` call. That final export is going to have is_the_final_export parameter being set to true. If `TrainSpec.max_steps` is `None`, then "when training ends" is undefined. We are going to train forever. In that case, `is_the_final_export` is going to be always False. I added a note about it.

After this change when C API is enabled, function support in Python is done with minimal use of Python code. In particular, we don't create or store FunctionDef in Python. Small changes include: - We don't use _hash_str for function comparisons in Python. Instead, we delegate this logic to TF_GraphCopyFunction in C API. - We checking for duplication function additions from _DefinedFunction.add_to_graph(graph) to Graph._add_function in all cases. This is more logical and make it easier to support both modes. - We change some error messages to be same in both modes. - Since we don't store FunctionDef in C API mode in Python but get it on demand, access to common attributes like name or signature can become expensive. To mitigate this, we cache the signature (OpDef) of the function in Python. Signatures are generally much smaller than whole definitions. - Add context manager for creating and destroying TF_Buffers. - Allow zero output tensorflow functions in Python The C API and C++ runtime support functions without outputs, but Python APIs explicitly disallowed them before this change. This change allows zero output functions in Python and cleans some hacks that were added to side-step regular Python function APIs before.

TrySimplifyAndReshapeUses should return a tensor not a node. Added a regression test that would have failed without this CL. ArithmeticOptimizer would have redirected the second input of concat to Split rather than Split:1.

This is a general cleanup -- less repeated code -- but it's also part of an effort to use IrArray more and llvm::Value less. In particular, many callsites would take the llvm::Value returned by EmitTargetAddressForOp and create an IrArray out of it, but then never attach AA info to that array. Having this function return void forces you to call GetIrArrayForOp(), which attaches the AA metadata appropriately. This change also gets rid of an unused arg to EmitTargetAddressForOp.

This is a general cleanup -- less repeated code -- but it's also part of an effort to use IrArray more and llvm::Value less. In particular, many callsites would take the llvm::Value returned by EmitTargetAddressForOp and create an IrArray out of it, but then never attach AA info to that array. Having this function return void forces you to call GetIrArrayForOp(), which attaches the AA metadata appropriately. This change also gets rid of an unused arg to EmitTargetAddressForOp.

Use them in training. When the training ends, the final export is performed via `Exporter.export()` call. That final export is going to have is_the_final_export parameter being set to true. If `TrainSpec.max_steps` is `None`, then "when training ends" is undefined. We are going to train forever. In that case, `is_the_final_export` is going to be always False. I added a note about it.

When the data has a rather extreme scale, this runs into precision issues. After this CL, state space models will first normalize, then use adjusted statistics on top of that normalization to estimate initial observation/transition noise. Also fixes an issue where start-of-series statistics were incorrect for the first batch (which only shows up with large input scales).

PiperOrigin-RevId: 170990425 --- Commit d016cb020 authored by Suharsh Sivakumar Committed by TensorFlower Gardener: Fix c++ gradients issue where multiple dependent outputs result in incorrect answer. The issue is that we incorrectly calculate the pending num_expected_backprops for outputs nodes when one output transitively depends on another. this is because we use output nodes as an indicator of when we need to end our traversal. Instead we should only use output nodes that don't transitively get consumed by other output nodes as end indicators for our traversal. This change implements that fix.

PiperOrigin-RevId: 170946536 --- Commit de14fcbb6 authored by Igor Saprykin Committed by TensorFlower Gardener: Support evaluation in `_TrainingExecutor.run_master()`. This CL aims to address the following TODO: # TODO(b/66720832): Once listener API is added into Estimator.train, the # eval and export process should be wrapped as a listener and passed to # _start_distributed_training. The expected behavior should be # 1. The export is invoked after each intermediate evaluation. # 2. The evaluation and export should be invoked correctly at the end of # training. This should be fine if the listener works as intended (it will # send the `after_save` signal for the final ckpt saving). 1. is achieved as follows: a. saving_evaluators are added to the CheckpointSaverHook's listeners inside the Estimator. b. MonitoredSession calls after_run() of CheckpointSaverHook, which in turn calls after_save on the listeners. 2. is achieved in a similar way, but when MonitoredSession calls .end() on CheckpointSaverHook.

PiperOrigin-RevId: 170922297 --- Commit d0c76cd18 authored by Igor Saprykin Committed by TensorFlower Gardener: Handle the absence of a fresh eval checkpoint in `run_local`. It is ~unexpected condition for an eval checkpoint to not be available after a train call to the estimator. There is a corner case when it is possible, but that's going to be resolved soon. This case is handled for continuous (distributed) evaluation differently. Instead of erroring out, we skip evaluation runs. That behavior is captured in the `test_skip_evaluation_due_to_ckpt` test.

This change also updates `rejection_resample()` to use `scan()` rather than a local `tf.ResourceVariable` for accumulating the number of times each class has been encountered.

An example of a bad ReshapeMover rewrite: BEFORE %reshape.1 = f32[1,1,128] reshape(f32[1,128] %dot) %constant = f32[128] constant({...}) %reshape.2 = f32[1,1,128] reshape(f32[128] %constant) %add = f32[1,1,128] add(f32[1,1,128] %reshape.1, f32[1,1,128] %reshape.2) AFTER %constant = f32[128] constant({...}) %add = f32[1,128] add(f32[1,128] %dot, f32[128] %constant) %reshape = f32[1,1,128] reshape(f32[1,128] %add) The problem in AFTER is the add now contains an implicit broadcast. One way to fix this is to re-shape the %constant to f32[1,128] before the %add. Instead of that, the fix introduced in this CL is to simply prevent the ReshapeMover from moving the reshapes in this case. A comment in reshape_mover.cc describes the complexities that led to this choice. Also added HloVerifiedTestBase, which keeps track of a default HloModule, and automatically runs HloVerifier at the end of every test. This is useful for many HLO tests; the tests of various passes can probably all use this. Three existing issues in reshape_mover_test.cc were found and fixed as a result.

This change merely creates the types, but does not register kernels that act on uint32/uint64 values. It also does not alter most op registration lists to include uint32/uint64 values. If desirable, that can be done in a subsequent change, although binary size will likely prove problematic if adding more kernels. The intent of the change is so XLA-compiled code can make use uint32/uint64 types. Since XLA does not use traditional TensorFlow kernels, using uint32/uint64 operators from XLA will require only uint32/uint64 op registrations, but will require few new kernel registrations.
