Change: 133293158

* Adds a test tf.Assert inside a function.
Change: 134855633

* Remove non-batch methods from operator_pd_cholesky if they have been merged with batch.
Recent changes to tensorflow linear algebra Ops merged batch/non-batch Ops.
This makes their separation un-necessary in OperatorPDCholesky.  Note that OperatorPDBase will still "dispatch based on batch"
since [non]batch-specific implementations still exist for matmul, and will probably
exist for some subset of Ops/Operators.

OperatorPDBase calls the _batch* method if the non-batch method does not exist, so this change will leave the _batch* methods as-is.

Change: 134979996

* Move inspector panel to its own component.

This reduces the complexity of `Projector` by delegating work to the `InspectorPanel`.

Also related:
 - Add an option to search by other metadata fields.
 - Introduce shared css styles used by every component.
 - Move data querying methods (findNeighbors, queryByField, etc) to data.ts. These methods are used by anyone that has access to the dataset (e.g. both the projector and the inspectorPanel use it).
Change: 134989405

* Created a tensorboard endpoint data/logdir for obtaining the logdir.
Change: 135001927

* numpy meshgrid parity
Change: 135002812

* tensor_bundle interface: accept StringPiece everywhere.

This facilitates the callers in that when passing "char*", "string", or
"StringPiece" no explicit conversions are needed.
Change: 135007288

* tfdbg: 1st check-in of curses UI and a demo

To run the demo, do:

./configure
bazel build tensorflow/python/debug:debug_fibonacci && bazel-bin/tensorflow/python/debug/debug_fibonacci

Barebone/backbone implementation of the curses-based command-line UI for tfdbg.

The fibonacci_network demo constucts a simple TF graph that computes the fibonacci sequence, wraps a tf.Session object with a CLI debugger wrapper session and calls its run() method. which leads to launching of the curses CLI.

The CLI debugger wrapper implements the BaseDebugWrapperSession.

The UI currently has only minimalist command set including
  ni: inspect node info
  lt: list all dumped tensors
  li: list node inputs
  lo: list node output recipients
  pt: print tensor.

Currently supported UI features:
  * command history navigation using Up/Down keys: with or without prefix
  * scroll large output with PgUp/PgDown/Home/End keys
  * terminal resize response

See CLI help output for more information.

Change: 135033928

* * Supports defining overloaded functions. I.e., defers the
  instantiation of the function definition until all input types are known.
* for convenience, adds more convert_to_tensor calls.
* adds None checking for better error reporting.
* cleanup function_test a bit so that it uses tf.logging.info consistently.
* changes the convention for coming up a function's name:
  * if func_name is explicitly given, stick with it.
  * otherwise, come up a name based on the python function info and a hash of the
    function definition.
* uses __doc__ to fill in func's op def description in the proto.
Change: 135036941

* Adding a ConditionalAccumulator class, which allows us to accumulate non-stale
gradients. Also adds SparseConditionalAccumulator, which supports IndexedSlices.
Change: 135037419

* minor changes in tf.learn.
Allow specifying saving checkpointing every N steps instead of every N secs, which is already supported by basic_session_run_hooks.CheckpointSaverHook but not supported by learn.RunConfig and estimator.
Change: 135055051

* Update generated Python Op docs.
Change: 135057486

* Cleanups to distributions tests.
  - Remove hack for sampling in beta test. Gamma sampler does not emit 0s any more.
  - Change tests to camel case..
Change: 135065764

* Show search results in the inspector panel.
Change: 135104864

* Get rid of vz-projector.ts's concept of 'highlighted points' and 'color accessors', moving slowly towards a model where we don't call accessors in inner loops. Visualizers have direct access to the selected points and neighbors, and can decide their own semantics for display. Projector now prepares a color array of unselected points, which the visualizers use to render. 3D labels are rendered with unselected point colors. Add the HoverContext for observing and reporting hover events.
Change: 135109425

* Migrating skflow examples to the tensorflow/examples/learn directory. Fixes #3364.
Change: 135109832

* tfdbg: CLI demo: debug_mnist

To run the demo, do:
bazel build -c opt tensorflow/python/debug:debug_mnist && bazel-bin/tensorflow/python/debug/debug_mnist --debug

See the doc file at: tensorflow/python/debug/examples/README.md for more details.
