* Add new QueueRunner optional argument: queue_closed_exception_types.Gravatar Eugene Brevdo2016-08-30
| | | | | | | | * This is a backwards compatible change. * Includes some extra helper functions in the tf.errors module. * Includes extension to the QueueRunner proto * Includes tests that QueueRunner.{from,to}_proto are backwards compatible. Change: 131791267
* Split NodeDef out of graph.proto into node_def.proto. Needed so weGravatar A. Unique TensorFlower2016-08-22
| | | | | can use NodeDef in FunctionDef. Change: 130982373
* Update copyright for 3p/tf/python.Gravatar A. Unique TensorFlower2016-06-02
| | | | Change: 123900456
* Raise proper tensorflow exceptions in a few more places:Gravatar A. Unique TensorFlower2016-05-03
| | | | | | | | - Add a context manager to deal with C apis that want a status object passed as an extra argument. - Use the context manager in session.py and session.i - Update tests. Change: 121430994
* Restrict the use of OUT_OF_RANGE to what it was intended to.Gravatar A. Unique TensorFlower2016-04-11
| | | | | | | | | | | | Clarify that OUT_OF_RANGE is raised only when reaching the end of input for interable contents. Change the few places where we incorrectly raised OUT_OF_RANGE to raise ILLEGAL_ARGUMENT instead. This will make code that catches the OUT_OF_RANGE exception more robust as it won't get confused by spurious uses of the exception class. Change: 119560848
* TensorFlow: For errors that are returned without NodeDefs or OpsGravatar Vijay Vasudevan2016-03-09
| | | | | | associated with them, make sure we return the correct underlying error code when available. Change: 116719327

* TensorFlow: Improve performance of AlexnetGravatar Manjunath Kudlur2015-11-20
| | | | | | | | | | | | | | | | | | | | | | Changes: * error message that refers to removed `DefaultSession` method. * -Wnull-conversion warnings * the "_start_time" attr for recvs when the flag "--brain_enable_scheduling_for_recvs" is set. * typo in tutorial data download progress message. * a typo ("however their installing"=>"however installing"). * typo, rename "TensorFlow Mechanics" to "How To" to be consistent with the website. * a typo ("subtact"=>"subtract"). * protobuf examples in comments in tensorflow::Example.proto. * formula formatting in MNIST beginner tutorial * negative fraction-of-queue-full stats * protobuf inclusion path so that Android demo will build under Blaze. * small typo (moderatly > moderately) * Session.run() to check that tensor arguments come from the session's graph. * another six import * seq2seq typo in bazel command Base CL: 108349164
* TensorFlow: upstream changes from the afternoon.Gravatar Vijay Vasudevan2015-11-11
