* TensorFlow: upstrea changes from git.Gravatar Vijay Vasudevan2015-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change 109628097 Fix gcc 4.8.1 compile Modified from patch by @assolini here: https://github.com/tensorflow/tensorflow/issues/405 Change 109624275 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). Change 109620599 - improved test a little to make it easier to understand as it serves as an example for users Change 109614953 TensorFlow: update tutorials/howtos to point to correct location of files, show python example in addition to bazel. Change 109612732 TensorFlow: move reading_data into examples, change data dir to /tmp/data. Validated that they all run, but these probably need a selftest at some point. Change 109608695 Apply 'gate_gradients' only when there is more than one real gradients. Change 109605014 There are 3 obvious places to start using TensorFlow. 2/3 of the starting points do not have a link to the installation instructions. Change 109604287 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/ There are no additional libraries this uses, so nothing else needs to be done Change 109601289 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 109596906 Add an is_unsigned property to dtype Change 109596830 Remove unnecessary fill in clip_by_value Change 109591880 Remove Android demo's libpthread.so dummy file (required by protobuf) from repo and generate it at compile-time. This makes the Android demo more portable, as the generated file will now always be the correct archictecture for linking. 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 tensorflow target with -fno-rtti. Change 109589018 Internal reworking of LSTMCell. Change 109588229 Allow bool-valued tensors to be persisted. Change 109577175 TensorBoard host defaults to 0.0.0.0 Change 109551438 TensorFlow: move mnist g3doc tutorials into tensorflow/examples. Update examples to point to the correct location. Adds tests to make sure they don't regress, do some lint cleanup. Base CL: 109630240
* TensorFlow: upstream changes to git.Gravatar Vijay Vasudevan2015-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change 109321497 Move all images to images directory to make docs versioning easier - adjust all paths in the docs to point to the new locations - remove some now redundant section-order tags added for the old website Change 109317807 Added a kernel op to compute the eigendecomposition of a self-adjoint matrix. Added a new kernel op called self_adjoint_eig (and a batch_self_adjoint_eig) that computes the eigendecomposition of a self-adjoint matrix. The return value is the concatenation of the eigenvalues as a row vector, and the eigenvectors. Change 109310773 Change `_read32()` in the MNIST input example to return an int. Currently we return a 1-D numpy array with 1 element. Numpy has recently deprecated the ability to treat this as a scalar, and as a result this tutorial fails. The fix returns the 0th element of the array instead. Change 109301269 Re-arrange TensorBoard demo files. Change 109273589 add ci_build for ci.tensorflow.org Change 109260293 Speed up NodeDef -> OpKernel process by not spending time generating an error message for missing "_kernel" attr that will be thrown away. Change 109257179 TensorFlow:make event_file_loader_test hermetic by using tempfile instead of fixed filenames. Without this change, running event_file_loader_test twice in the same client (locally) causes it to fail, because it writes into the same file and appends another event, instead of starting from scratch. Change 109256464 Minor cleanup in TensorBoard server code Change 109255382 Change to reduce critical section times in gpu_event_mgr.h: (1) Call stream->ThenRecordEvent outside the EventMgr critical section (2) Do memory deallocation outside the critical section Speeds up one configuration of ptb_word_lm from 2924 words per second (wps) to 3278 wps on my desktop machine with a Titan X. Change 109254843 Fix use of uninitialized memory in test. Change 109250995 python_config.sh needs a license header Otherwise the license test fails. Change 109249914 add ci_build for ci.tensorflow.org Change 109249397 Fixes reduce_sum (complex) on GPU segfaults. Fixes #357 Change 109245652 add ci_build for ci.tensorflow.org Base CL: 109321563
* TensorFlow: upstream changes to gitGravatar Manjunath Kudlur2015-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change 109195845 Fix TensorFlow for build against Bazel 0.1.2rc2 Two things are currently broken with TensorFlow and Bazel 0.1.2: - Bazel now use sandboxing by default on Linux and have fixed it for cc_* rules. Undeclared headers are not mounted in the sandbox which make several cc_* rules fails. - Bazel now enforce strict header checking and some target were missing headers even though the headers were mounted in the sandbox. This change adds a "strict_headers" target that globs every headers of the core library and add it to the `tf_cc_tests` targets. Change 109162708 Fix various website issues - Fix headline in os_setup.md - Fix #anchor links Change 109162129 Fix numbers in mnist tutorial, fixes #362 Change 109158967 Fix typo in word2vec tutorial, fixes #347 Change 109151855 Fix tile and its gradient for scalars on GPUs Eigen doesn't handle scalars on GPUs in all cases. Fortunately, both tile and its gradient are the identity for scalars, so we can just copy the input to the output. Fixes https://github.com/tensorflow/tensorflow/issues/391. Change 109140763 Support int32 and int64 in tf.random_uniform This requires a new RandomUniformInt op on the C++ side since the op needs to know minval and maxval. Fixes https://github.com/tensorflow/tensorflow/issues/364. Change 109140738 Fix spacing in docs. Change 109140030 Fix content nav to not hide the bottom 100 or so px. Change 109139967 Add license files to TensorBoard files, fix mnist_with_summaries test Change 109138333 Fix typos in docstring Change 109138098 Fix some missing resources in the website. Fixes #366. Change 109123771 Make sparse_to_dense's default_value default to 0 Nearly all uses of sparse_to_dense use 0 as the default. The same goes for sparse_tensor_to_dense. Base CL: 109198336
* 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: Removal of large assets and small other fixes.Gravatar Vijay Vasudevan2015-11-18
| | | | | | | | | | | | | | | | | | | | | | | Changes: - Remove all large assets from the repoistory, incuding the other 50MiB model protobuf and a lot of images in our g3doc directory. We will maintain these assets externally for now. g3doc images may be broken for a little bit, but the website will be fine, which is the important resource. By @vrv and @petewarden. Updates READMES to reflect the external model resources. - Fix to saver's latest_checkpoint function by Zhifeng - Made protos visibility public by @vrv - Updates to docs by @mrry, Andy - Embed tensorboard resource for summary icon by Daniel - More updates to backwars compat by @josh11b Base CL: 108194981
