Igor Ganichev [Fri, 25 May 2018 20:58:51 +0000 (13:58 -0700)]
Add EagerTensor profiler and device shape utilities

This change includes the following steps to make
EagerTensor profiler work:
 - Add a PaddedShapeFn to XlaDevice::Metadata. We need a
   backend-independent way to get a fully-padded shape and
   its layout on the device. This function is set during
   device construction. CPU and GPU devices effectively get
   an identity function since they neither change the layout
   nor pad. TPU gets the appropriate function.
 - Add TFE_TensorDebugInfo struct and C API methods for it.
   These methods are necessary to fetch the shape and layout
   from under the C API to the Python level. This can be a home
   for more debug information later.
 - Make EagerTensor weak referencable. This involves adding a
   pointer to the list of current weak references. This addition
   should have negligible overhead when profiler is not used.
   The only operations on this field are setting it to null on
   construction and checking if it is null on destruction.
 - Adding C++ functions callable from Python to register an instance
   of EagerTensorProfiler and retrieve debug information for a given
   EagerTensor. These functions are used in the new "inspect" module.
 - Finally, writing the actual profiler.

Alexandre Passos [Fri, 25 May 2018 20:20:13 +0000 (13:20 -0700)]
Public API to switch between eager execution and graph building.

Now, after tf.enable_eager_execution() has been executed, entering the context
manager of a tf.Graph will enable graph mode. So, for example

```
tf.enable_eager_execution()
with tf.Graph().as_default():
  c = tf.constant(1.0)  # this is a graph tensor
c2 = tf.constant(1.0)  # this is an eager tensor
```

The main use-case of this is allowing documentation writers to make a single
notebook which starts with eager execution and seamlessly transitions to
building graphs.

This also makes many explicit enablings of graph mode in the code redundant
(a cleanup cl will follow).

6 years agoAdd ScopedAllocatorOptimizer in support of CollectiveReduce.
A. Unique TensorFlower [Fri, 25 May 2018 19:54:49 +0000 (12:54 -0700)]
Add ScopedAllocatorOptimizer in support of CollectiveReduce.

The efficiency of CollectiveReduce is greatly improved by merging
multiple parallel reductions over smaller tensors into a single
reduction over a larger tensor that is the concatentation of the
smaller tensors.  Because CollectiveReduce is essentially an
element-wise array operation which operates on a 1-D reshape of
the input tensor it is eligible for a ScopedAllocation optimization.

The optimization works by looking for serially independent instances
of CollectiveReduce that lie within the same name-scope tier and
have the same control-flow (e.g. loop) embedding structure.  Where
two or more such nodes are found the upstream nodes that generate
their inputs are modified to write their outputs into consecutive
regions of a single tensor buffer maintained by a ScopedAllocator.
The multiple CollectiveReduce nodes are then replaced by a single
CollectiveReduce that operates in-place on the backing buffer.

The effectiveness of the optimization depends on there being candidate
CollectiveReduce nodes with these characteristics that become eligible
for execution at close to the same time.  If the name scope is too
large, and includes nodes that become execution eligible at very different
times, this graph rewrite could result in a slowdown.

Note that this optimization is experimental: it is not guaranteed to
work, especially for ops other than CollectiveReduce.
