* Add missing tf.contrib.receptive_field dependencies.Gravatar A. Unique TensorFlower2018-01-11

* Increase number of inlined elements in EdgeSet from 2 to 4 to speed up graph ↵Gravatar A. Unique TensorFlower2018-01-11
| | | | | | | | construction and reduce startup time in TensorFlow. In the motivating case, this change decreases the time for a RegisterGraph RPC with a large graph from 10 minutes to 40s. Without this change, a large portion of the time is spent walking the red-black tree. PiperOrigin-RevId: 181643594
* Enable stacktrace printing ont test failures for python tests.Gravatar Gunhan Gulsoy2018-01-11
| | | | PiperOrigin-RevId: 181642475
* Remove debugging print statement from tf.image.random_flip_left_right.Gravatar Chris Ying2018-01-11

* [XLA:GPU] Add reduction-to-scalar code.Gravatar Justin Lebar2018-01-11
| | | | | | | | | | | Adds special code for reducing a tensor of arbitrary rank to a scalar. This is similar to the column reduction code that we used to run, but it has a shfl loop at the end like the row reduction code. The result is much faster for the reduction-to-scalar case. (A shfl loop doesn't make sense for the column reduction case.) PiperOrigin-RevId: 181640117
* Change ios_tensorflow_lib to depend on ios_tensorflow_lib_lite.Gravatar A. Unique TensorFlower2018-01-11

* Comments for the functors in concat_libGravatar Alexandre Passos2018-01-11
| | | | PiperOrigin-RevId: 181635835
* Add support for for loops.Gravatar A. Unique TensorFlower2018-01-11
| | | | | | | | | Generalize the static analysis across while and for loops. Convert len builtin to tf.shape()[0]. Add for loop canonicalization and companion tests. Modify the template behavior for Name nodes to let the template control the target, which allows simplifying the caller. PiperOrigin-RevId: 181633983
* [tf.data] Improve documentation for `Dataset.batch()` wrt. small final batches.Gravatar Derek Murray2018-01-11
| | | | | | This partially addresses the concerns in issue #13161. PiperOrigin-RevId: 181629980

* [XLA] Make HLO CSE faster.Gravatar A. Unique TensorFlower2018-01-11
| | | | | | Passing around copies of std::functions incurs heap allocations and deallocations, which, unfortunately, matters in this case. Minimize the amount of copies. PiperOrigin-RevId: 181625079
* Changing the default value of the momentum constant to 0.9.Gravatar A. Unique TensorFlower2018-01-11
| | | | | | Changing the default value of colocate_gradients_with_ops to True. PiperOrigin-RevId: 181624864

* [XLA:GPU] Specify an explicit alignment on args to kernels.Gravatar Justin Lebar2018-01-11
| | | | | | | This allows LLVM to vectorize loads/stores in these kernels, among other things. PiperOrigin-RevId: 181618991

* Allow backends to specify a custom ShapeVerifier to HloVerifier.Gravatar Brian Patton2018-01-11
| | | | | | | | Remove obsolete shape_size_fn_ from HloVerifier/ShapeVerifier. Adds a rank check to FFT shape inference. PiperOrigin-RevId: 181601294
* [TF/XLA] Add stricter checks of buffer sizes within colocated buffer sets.Gravatar Todd Wang2018-01-10
| | | | | | | | | Note that there are already existing checks in BufferAllocation::AddAssignment to ensure all buffers are no larger than the allocation. But colocated buffer sets are used to handle forced aliasing, e.g. kWhile, kCall and kConditional, which require all buffers to be identically sized. PiperOrigin-RevId: 181565074

* Fix for graph execution of gradients_functionGravatar Allen Lavoie2018-01-10
| | | | | | Shapes were not correctly converted to C types. PiperOrigin-RevId: 181546120
* Fetch OpDef if necessary in Operation.__init__Gravatar Skye Wanderman-Milne2018-01-10
| | | | | | | | Also enables the C API in slot_create_test.py, which exercises the new behavior (previously it would fail because it would create an op with no OpDef and list inputs). PiperOrigin-RevId: 181544033

* Add --fat_apk_cpu=arm64-v8a for arm64 Android buildsGravatar Austin Anderson2018-01-10
| | | | | | | | Bazel silently uses the wrong build settings for --config=android_arm64 (--cpu=arm64-v8a is not enough), and actually still uses armeabi-v7a in at least some cases. --fat_apk_cpu fixes this. See #15581 for more. PiperOrigin-RevId: 181525260

* [TF:XLA] Fix infinite loop in HLO data flow analysis.Gravatar A. Unique TensorFlower2018-01-10
| | | | | | | Merge input values at phi nodes correctly: If a phi operand is the phi itself, and the other operands are all the same, then the phi node is redundant. PiperOrigin-RevId: 181521522

* [XLA] Clean up our handling of ExecutionProfile and add a test caseGravatar Sanjoy Das2018-01-10
| | | | | | ExecutionProfile::compute_cycle_count never worked for CPU and GPU with Hlo profiling disabled, as far as I can tell. PiperOrigin-RevId: 181517824

* Revert PlaceholderWithDefault logic in constant_folding.cc.Gravatar Skye Wanderman-Milne2018-01-10

* Support nesting EagerTemplate objects.Gravatar Akshay Agrawal2018-01-10
| | | | | | | * Nesting is implemented by sharing a single EagerVariableStore among a top-level EagerTemplate and all children EagerTemplate objects that are nested underneath it. Variables added to an EagerTemplate object are also added to all EagerTemplate objects under which it is nested. * This change also simplifies the implementation of __call__ for both Template and EagerTemplate.
