The repr replaces the default Python representation for an object with
information about the Tensor's name, shape and dtype. TensorShape's
new str() is a more compact representation that makes it easier to
tell, at a glance, what the shape represents.

For example:

    print repr(tf.placeholder(tf.qint32, shape=(32, None, 2), name="c"))
    # ==> <tf.Tensor 'c:0' shape=(32, ?, 2) dtype=qint32>

Fixes #460.

Change 110055925
	Clean up interface for adjust_contrast and adjust_brightness.
	- Simplify kernel for adjust_contrast and remove all min/max and casts.
	- Change semantics of delta arg to adjust_brightness (always in [0,1)), and adjust users.
	- Add saturate_cast for casting images without over/underflow problems.
	- Add new numbers for adjust_contrast benchmark.

	This CL makes two changes to the public API:
	- It changes the semantics of the delta parameter of adjust_brightness, which was in the same range as the input image before, and now is always in [0,1).
	- It changes the semantics of adjust_contrast (the cc op), which wasn't hidden, but was shadowed by the python wrapper in image_ops. It's a little questionable whether this function was part of the public API. It definitely shouldn't have been. It is now hidden, although now it could be part of the public API, albeit with a different name.
Change 110054427

	* rename ci_build cache directory to bazel-ci_build-cache
	* sync ci_build/Dockerfile.cpu with docker/Dockerfile.devel
	* use "FROM nvidia/cuda:..." for gpu container
	* therefore no need of the tensorflow_extra_deps directory anymore
	* share install code between containers using  ./install/*.sh scripts
	* do not inherit (and override FROM clausule in dockerfiles anymore)
	* print bazel test errors to stderr

Base CL: 110043747

Base CL: 110018194

Change 110010103
	Implementing SparseSplitOp.
	The op takes a sparse tensor (list, values and shape), split_dim and num_splits and produces a list of num_splits tensors where the shape of each tensor is the shape of the original tensor except split_dim = shape[split_dim +num_split - 1 / num_split]. in case if shape[split_dim] is not an integer multiple of num_split an extra one dimension get added to the slices starting from 0.
	For example if the input shape is a [2, 10] split_dim = 1, num_split = 3
	output shapes will be [[2, 4], [2, 4], [2, 2]].

	The Op register shape to [Unknown, dim] for indices tensors and [Unknown] for the values tensor because shape can't be inferred without evaluate input tensors.

Base CL: 110012853

Change 110004767
	Add Cast to list of supported ConstantValue ops, mainly useful for shape inference
Change 110002200
	Bug fix for b/24814668. The fix uses mdevin's CL/109324239, which adds support to clear control dependency and control flow contexts.

	Bug fix for b/25914830. We now clear the control related contexts for initial values of variables in adagrad.
Change 110000213
	Further (minor) improvements to print usage in docs and tutorials
Change 109975099
	Update `tensor_util.ConstantValue()` to return scalars when appropriate.

	The `ConstantValue()` implementations for `tf.size()` and `tf.rank()`
	were returning single-element numpy vectors, whereas the op
	implementations produce scalar outputs.
Change 109950165

	Fixes #411
Change 109824286
	Change TensorBoard/TAG to 4
Change 109824197
	Update tutorials and documentation usage of print to use print as function not statement.
	This way you can copy+paste code in a python3 context and it will still work.
Change 109824020
	Fix another case where TensorBoard discards values after a restart.

	We also need to not discard on graph_def, since user code or SummaryWriter may add graph_defs at step 0 after every restart.
Change 109821924
	Defines Templates for variable sharing.

	A Template is a function that generates a sub-graph with the same variables each time it is called.

	Two different templates defined with the same underlying function also return different variables.
Change 109815801
	Don't instatiate the eigen expressions for additions and subtractions of
	boolean since they won't be called. This reduces the size of the binary a bit.
Change 109795730
	Allow casts to and from int8
Change 109791914
	Python 3 fix: filter has no len

	gradients.py calls len on the output of filter.  A call to tuple is needed in
	between.

	Not sure why this wasn't caught when we ran the Python 3 tests.  If I break it
	for Python 2 several tests break.
Change 109757009
	Fix minor grammatical errors in about.html

	The missing article needs no justification, I think.
	has -> have, because subjects are 'usability and functionality', not 'TensorFlow'.
	and also -> and, because 'also' is superfluous in this use.

	TensorFlow: remove one more clang warning (class / struct inconsistency).
Change 109741933
	Document default for max_images in tf.image_summary

	It used to say max_images=None which hid the C++ defalut of 3.
	Now it says max_images=3.

	Fixes https://github.com/tensorflow/tensorflow/issues/441.

	It's unfortunate that an edit-distance-5 change produces such a large CL.
Change 109741569
	Update generated Op docs.
Change 109739599
	Renaming the Python variables in the layer weights of the fully connected
	MNIST model so that the variable and the TensorFlow names are different. This
	allows the documentation to be more explicit about the distinction between the
	weights and biases of different layers. Also, the documentation gets to
	describe the whether the TF name or the Python name is being used.

Base CL: 109851372

Change 109738410
	Don't crash if an attribute contains an invalid shape

	Using GetAttr to retrieve a TensorShape caused a process crash if the shape

	messages (and Python exceptions).

	Adding an option to create a new thread-pool for each session.
Change 109640570

	Take the snapshot of stream-executor.
	+ Expose an interface for scratch space allocation in the interface.

Change 109638559
	Let image_summary accept uint8 input

	This allows users to do their own normalization / scaling if the default
	(very weird) behavior of image_summary is undesired.

	This required a slight tweak to fake_input.cc to make polymorphically typed
	fake inputs infer if their type attr is not set but has a default.

	Unfortunately, adding a second valid type to image_summary *disables* automatic
	implicit conversion from np.float64 to tf.float32, so this change is slightly
	backwards incompatible.

Change 109632108
	Move HSV <> RGB conversions, grayscale conversions, and adjust_* ops back to tensorflow
	- make GPU-capable version of RGBToHSV and HSVToRGB, allows only float input/output
	- change docs to reflect new size constraints
	- change HSV format to be [0,1] for all components
	- add automatic dtype conversion for all adjust_* and grayscale conversion ops
	- fix up docs
Change 109631077

	Make preview frame ImageReader global so that it does not get GC'd.

	This may fix an issue with connecting to the camera on some devices where the underlying Surface is prematurely cleaned up (http://stackoverflow.com/questions/33437961/android-camera-2-api-bufferqueue-has-been-abandoned).

	Make the `tf.reshape` shape function more restrictive.

	Previously, it did not raise a construction-time error if the input
	shape and the new shape were incompatible; now it detects this and
	raises a `ValueError`.
Change 109603375
	TensorFlow: Move word2vec_basic.py from g3doc/ to examples/

	TensorBoard tag 3
Change 109600908
	Decrease number of scalar values stored by TensorBoard.
	10k is more than displays nicely.
Change 109599464
	Fix "smart restart" functionality in TensorBoard (it throws away dead data)
	After restarts, a file_version event is created that always has step 0.
	We need to ignore this.
Change 109597667
	Switch to using /dev/urandom for TensorFlow randomness.

	Using /dev/random leads to slowdown when running in an environment
	with poor access to an entropy source (such as some VMs). /dev/urandom
	has more predictable performance, and we don't require
	cryptographically secure random number generation, so a PRNG is good
	enough.

	Also removes the use of the RNG in DirectSession construction. This
	was being used to generate a session handle, which is not necessary
	(since a DirectSession owns its devices, we don't need a unique handle
	to key the OpSegment objects registered with the various devices).

	This addresses bugs that have been reported on the mailing list and
	Stack Overflow.

Change 109589028
	Isolating out the RTTI part of TensorFlow and add non-RTTI backups for Android.
	This saves about 400KB of the compiled library, when compiling the Android

	Various performance improvements in low-level node execution code paths.

	Speeds up ptb_word_lm on my desktop with a Titan X from
	3638 words per second to 3751 words per second (3.1% speedup).

	Changes include:

	o Avoided many strcmp operations per node execution and extra touches
	of cache lines in executor.cc, by making all the various IsMerge,
	IsSwitch, IsSend, etc. operations instead be based on an internal enum
	value that is pre-computed at Node construction time, rather than doing
	string comparisons against node->type_string().  We were doing about
	6 such comparisons per executed node.

	o Removed mutex_lock in executor.cc in ExecutorState::Process.  The
	lock was not needed and the comment about the iterations array being
	potentially resized is not true (the iterations arrays are created
	with a fixed size).  Checked with yuanbyu to confirm this.

	o Added new two-argument port::Tracing::ScopedAnnotation constructor
	that takes two StringPiece arguments, and only concatenates them
	lazily if tracing is enabled.  Also changed the code in
	platform/tracing.{h,cc} so that the ScopedAnnotation constructor and
	the TraceMe constructor can be inlined.

	o In BaseGPUDevice::Compute, used the two-argument ScopedAnnotation
	constructor to avoid doing StrCat(opkernel->name(), ":",
	op_kernel->type_string()) on every node execution on a GPU.

	o Introduced a new TensorReference class that just holds a reference to an
	underlying TensorBuffer, and requires an explicit Unref().

	o Changed the EventMgr interface to take a vector of TensorReference objects
	for EventMgr::ThenDeleteTensors, rather than a vector of Tensor objects.

	o Used TensorReference in a few places in gpu_util.cc

	o Minor: switched to using InlinedVectors in a few places to get better
	cache locality.
Change 109456692

	TensorFlow: make the helper libraries for various models available

	change here is moving the GPU images to use the NVidia containers which
	include cudnn and other build-time dependencies, dramatically simplifying both
