- XLA (experimental): initial release of XLA, a domain-specific compiler for TensorFlow graphs, that targets CPUs and GPUs.
- TensorFlow Debugger (tfdbg): command-line interface and API.
- New python 3 docker images added.
- Made pip packages pypi compliant. TensorFlow can now be installed by
pip install tensorflow
command. - Several python API calls have been changed to resemble NumPy more closely.
- Android: person detection + tracking demo implementing Scalable Object Detection using Deep Neural Networks.
- New (experimental) Java API.
- Add new Android image stylization demo based on "A Learned Representation For Artistic Style", and add YOLO object detector support.
To help you upgrade your existing TensorFlow Python code to match the API changes below, we have prepared a conversion script.
- TensorFlow/models have been moved to a separate github repository.
- Division and modulus operators (/, //, %) now match Python (flooring)
semantics. This applies to
tf.div
andtf.mod
as well. To obtain forced integer truncation based behaviors you can usetf.truncatediv
andtf.truncatemod
. tf.divide()
is now the recommended division function.tf.div()
will remain, but its semantics do not respond to Python 3 orfrom future
mechanisms.- tf.reverse() now takes indices of axes to be reversed. E.g.
tf.reverse(a, [True, False, True])
must now be written astf.reverse(a, [0, 2])
.tf.reverse_v2()
will remain until 1.0 final. tf.mul
,tf.sub
andtf.neg
are deprecated in favor oftf.multiply
,tf.subtract
andtf.negative
.tf.pack
andtf.unpack
are deprecated in favor oftf.stack
andtf.unstack
.TensorArray.pack
andTensorArray.unpack
are getting deprecated in favor ofTensorArray.stack
andTensorArray.unstack
.- The following Python functions have had their arguments changed to use
axis
when referring to specific dimensions. We have kept the old keyword arguments for compatibility currently, but we will be removing them well before the final 1.0.tf.argmax
:dimension
becomesaxis
tf.argmin

tf.listdiff
has been renamed totf.setdiff1d
to match NumPy naming.tf.inv
has been renamed to betf.reciprocal
(component-wise reciprocal) to avoid confusion withnp.inv
which is matrix inversion- tf.round now uses banker's rounding (round to even) semantics to match NumPy.
tf.split
now takes arguments in a reversed order and with different keywords. In particular, we now match NumPy order astf.split(value, num_or_size_splits, axis)
.tf.sparse_split
now takes arguments in reversed order and with different keywords. In particular we now match NumPy order astf.sparse_split(sp_input, num_split, axis)
. NOTE: we have temporarily madetf.sparse_split
require keyword arguments.tf.concat
now takes arguments in reversed order and with different keywords. In particular we now match NumPy order astf.concat(values, axis, name)
.tf.image.decode_jpeg
by default uses the faster DCT method, sacrificing a little fidelity for improved speed. One can revert to the old behavior by specifying the attributedct_method='INTEGER_ACCURATE'
.tf.complex_abs
has been removed from the Python interface.tf.abs
supports complex tensors and should be used instead.- In the C++ API (in tensorflow/cc), Input, Output, etc. have moved from the tensorflow::ops namespace to tensorflow.
- Template.
var_scope
property renamed to.variable_scope
- SyncReplicasOptimizer is removed and SyncReplicasOptimizerV2 renamed to SyncReplicasOptimizer.
tf.zeros_initializer()
andtf.ones_initializer()
now return a callable that must be called with initializer arguments, in your code replacetf.zeros_initializer
withtf.zeros_initializer()
.SparseTensor.shape
has been renamed toSparseTensor.dense_shape
. Same forSparseTensorValue.shape
.- Replace tf.scalar_summary, tf.histogram_summary, tf.audio_summary, tf.image_summary with tf.summary.scalar, tf.summary.histogram, tf.summary.audio, tf.summary.image, respectively. The new summary ops take name rather than tag as their first argument, meaning summary ops now respect TensorFlow name scopes.
- Replace tf.train.SummaryWriter and tf.train.SummaryWriterCache with tf.summary.FileWriter and tf.summary.FileWriterCache.
- Removes RegisterShape from public API. Use C++ shape function registration instead.
- Deprecated
_ref
dtypes from the python API. - In the C++ API (in tensorflow/cc), Input, Output, etc. have moved from the tensorflow::ops namespace to tensorflow.
- Change arg order for
{softmax,sparse_softmax,sigmoid}_cross_entropy_with_logits
to be (labels, predictions), and force use of named args. - tf.nn.rnn_cell.* and most functions in tf.nn.rnn.* (with the exception of dynamic_rnn and raw_rnn) are temporarily in tf.contrib.rnn. They will be moved back into core for TF 1.1.
- Numerous C++ API updates.
- New op:
parallel_stack
. - Introducing common tf io compression options constants for RecordReader/RecordWriter.
- Add
sparse_column_with_vocabulary_file
, to specify a feature column that transform string features to IDs, where the mapping is defined by a vocabulary file. - Added
index_to_string_table
which returns a lookup table that maps indices to strings. - Add
string_to_index_table

recursive_create_dir
. - Added an op for QR factorizations.
- Divides and mods in Python API now use flooring (Python) semantics.
- Android: pre-built libs are now built nightly.
- Android: cmake/gradle build for TensorFlow Inference library under
contrib/android/cmake
- Android: Much more robust Session initialization code.
- Android: TF stats now exposed directly in demo and log when debug mode is active

- TensorFlow now builds and runs on Microsoft Windows (tested on Windows 10, Windows 7, and Windows Server 2016). Supported languages include Python (via a pip package) and C++. CUDA 8.0 and cuDNN 5.1 are supported for GPU acceleration. Known limitations include: It is not currently possible to load a custom op library. The GCS and HDFS file systems are not currently supported. The following ops are not currently implemented: Dequantize, QuantizeAndDequantize, QuantizedAvgPool, QuantizedBatchNomWithGlobalNormalization, QuantizedBiasAdd, QuantizedConcat, QuantizedConv2D, QuantizedMatmul, QuantizedMaxPool, QuantizeDownAndShrinkRange, QuantizedRelu, QuantizedRelu6, QuantizedReshape, QuantizeV2, RequantizationRange, and Requantize.
- Go: Experimental API in Go to create and execute graphs (https://godoc.org/github.com/tensorflow/tensorflow/tensorflow/go)
- New checkpoint format becomes the default in
tf.train.Saver
. Old V1 checkpoints continue to be readable; controlled by thewrite_version
argument,tf.train.Saver
now by default writes out in the new V2 format. It significantly reduces the peak memory required and latency incurred during restore. - Added a new library for library of matrix-free (iterative) solvers for linear equations, linear least-squares, eigenvalues and singular values in tensorflow/contrib/solvers. Initial version has lanczos bidiagonalization, conjugate gradients and CGLS.
- Added gradients for
matrix_solve_ls
andself_adjoint_eig
. - Large cleanup to add second order gradient for ops with C++ gradients and improve existing gradients such that most ops can now be differentiated multiple times.
- Added a solver for ordinary differential equations,
tf.contrib.integrate.odeint
. - New contrib module for tensors with named axes,
tf.contrib.labeled_tensor
. - Visualization of embeddings in TensorBoard.
BusAdjacency
enum replaced with a protocol bufferDeviceLocality
. PCI bus indexing now starts from 1 instead of 0, andbus_id==0
is used where previouslyBUS_ANY
was used.Env::FileExists
andFileSystem::FileExists
now return a tensorflow::Status instead of a bool. Any callers to this function can be converted to a bool by adding .ok() to the call.- The C API type
TF_SessionWithGraph
has been renamed toTF_Session
, indicating its preferred use in language bindings for TensorFlow. What was previouslyTF_Session
has been renamed toTF_DeprecatedSession
. - Renamed
TF_Port
toTF_Output
in the C API. - Removes RegisterShape from public API. Use C++ shape function registration instead.
indexing now starts from 1 instead of 0, and
bus_id==0
is used where previouslyBUS_ANY
was used. - Most RNN cells and RNN functions now use different variable scopes to be
consistent with layers (
tf.contrib.layers
). This means old checkpoints written using this code will not load after this change without providingSaver
a list of variable renames. Examples of variable scope changes includeRNN
->rnn
intf.nn.rnn
,tf.nn.dynamic_rnn
and moving fromLinear/Matrix
->weights
andLinear/Bias
->biases
in most RNN cells. - Deprecated tf.select op. tf.where should be used instead.
SparseTensor.shape
has been renamed toSparseTensor.dense_shape
. Same forSparseTensorValue.shape
.Env::FileExists
andFileSystem::FileExists
now return atensorflow::Status
instead of a bool. Any callers to this function can be converted to a bool by adding.ok()
to the call.- C API: Type
TF_SessionWithGraph
has been renamed toTF_Session
, indicating its preferred use in language bindings for TensorFlow. What was previouslyTF_Session
has been renamed toTF_DeprecatedSession
. - C API: Renamed
TF_Port
toTF_Output
. - C API: The caller retains ownership of
TF_Tensor
objects provided toTF_Run
,TF_SessionRun
,TF_SetAttrTensor
etc. - Renamed
tf.image.per_image_whitening()
totf.image.per_image_standardization()
- Move Summary protobuf constructors to
tf.summary
submodule. - Deprecate
histogram_summary
,audio_summary
,scalar_summary
,image_summary
,merge_summary
, andmerge_all_summaries
. - Combined
batch_*
and regular version of linear algebra and FFT ops. The regular op now handles batches as well. Allbatch_*
Python interfaces were removed. tf.all_variables
,tf.VARIABLES
andtf.initialize_all_variables
renamed totf.global_variables
,tf.GLOBAL_VARIABLES
andtf.global_variables_initializer
respectively.tf.zeros_initializer()
andtf.ones_initializer()
now return a callable that must be called with initializer arguments, in your code replacetf.zeros_initializer
withtf.zeros_initializer()
- Use threadsafe version of
lgamma
function. - Fix
tf.sqrt
handling of negative arguments. - Fixed bug causing incorrect number of threads to be used for multi-threaded benchmarks.

- HDFS Support.
- Adds Fused LSTM support via cuDNN 5 in
tensorflow/contrib/cudnn_rnn
. - Improved support for NumPy style basic slicing including non-1 strides,
ellipses, newaxis, and negative indices. For example complicated expressions
like
foo[1, 2:4, tf.newaxis, ..., :-3:-1, :]
are now supported. In addition we have preliminary (non-broadcasting) support for sliced assignment to variables. In particular one can writevar[1:3].assign([1,11,111])
. - Deprecated
tf.op_scope
andtf.variable_op_scope
in favor of a unifiedtf.name_scope
andtf.variable_scope
. The new argument order oftf.variable_scope
is incompatible with previous versions. - Introducing
core/util/tensor_bundle
module: a module to efficiently serialize/deserialize tensors to disk. Will be used in TF's new checkpoint format. - Added tf.svd for computing the singular value decomposition (SVD) of dense matrices or batches of matrices (CPU only).
- Added gradients for eigenvalues and eigenvectors computed using
self_adjoint_eig
orself_adjoint_eigvals
. - Eliminated
batch_*
methods for most linear algebra and FFT ops and promoted the non-batch version of the ops to handle batches of matrices. - Tracing/timeline support for distributed runtime (no GPU profiler yet).
- C API gives access to inferred shapes with
TF_GraphGetTensorNumDims
andTF_GraphGetTensorShape
. - Shape functions for core ops have moved to C++ via
REGISTER_OP(...).SetShapeFn(...)
. Python shape inference RegisterShape calls use the C++ shape functions withcommon_shapes.call_cpp_shape_fn
. A future release will removeRegisterShape
from python.
- Documentation now includes operator overloads on Tensor and Variable.
tensorflow.__git_version__
now allows users to identify the version of the code that TensorFlow was compiled with. We also havetensorflow.__git_compiler__
which identifies the compiler used to compile TensorFlow's core.- Improved multi-threaded performance of
batch_matmul
. - LSTMCell, BasicLSTMCell, and MultiRNNCell constructors now default to
state_is_tuple=True
. For a quick fix while transitioning to the new default, simply pass the argumentstate_is_tuple=False
. - DeviceFactory's AddDevices and CreateDevices functions now return a Status instead of void.
- Int32 elements of list(type) arguments are no longer placed in host memory by default. If necessary, a list(type) argument to a kernel can be placed in host memory using a HostMemory annotation.
uniform_unit_scaling_initializer()
no longer takes afull_shape
arg, instead relying on the partition info passed to the initializer function when it's called.- The NodeDef protocol message is now defined in its own file
node_def.proto
instead of graph.proto
. ops.NoGradient
was renamedops.NotDifferentiable
.ops.NoGradient
will be removed soon.dot.h
/ DotGraph was removed (it was an early analysis tool prior to TensorBoard, no longer that useful). It remains in history should someone find the code useful.- re2 / regexp.h was removed from being a public interface of TF. Should users need regular expressions, they should depend on the RE2 library directly rather than via TensorFlow.

- Performance improvements
- Various bugfixes
- Documentation fixes and improvements
AdjustContrast
kernel deprecated, new kernelAdjustContrastv2
takes and outputs float only.adjust_contrast
now takes all data types.adjust_brightness
'sdelta
argument is now always assumed to be in[0,1]
(as is the norm for images in floating point formats), independent of the data type of the input image.- The image processing ops do not take
min
andmax
inputs any more, casting safety is handled bysaturate_cast
, which makes sure over- and underflows are handled before casting to data types with smaller ranges. - For C++ API users:
IsLegacyScalar
andIsLegacyVector
are now gone fromTensorShapeUtils
since TensorFlow is scalar strict within Google (for example, the shape argument totf.reshape
can't be a scalar anymore). The open source release was already scalar strict, so outside GoogleIsScalar
andIsVector
are exact replacements. - The following files are being removed from
tensorflow/core/public/
:env.h
->../platform/env.h
status.h
->../lib/core/status.h
tensor.h
->../framework/tensor.h
tensor_shape.h
->../framework/tensor_shape.h
partial_tensor_shape.h
->../framework/partial_tensor_shape.h
tensorflow_server.h
deleted
- For C++ API users:
TensorShape::ShortDebugString
has been renamed toDebugString
, and the previousDebugString
behavior is gone (it was needlessly verbose and produced a confusing empty string for scalars). GraphOptions.skip_common_subexpression_elimination
has been removed. All graph optimizer options are now specified viaGraphOptions.OptimizerOptions
.ASSERT_OK
/EXPECT_OK
macros conflicted with external projects, so they were renamedTF_ASSERT_OK
,TF_EXPECT_OK
. The existing macros are currently maintained for short-term compatibility but will be removed.- The non-public
nn.rnn
and the variousnn.seq2seq
methods now return just the final state instead of the list of all states. tf.scatter_update
now no longer guarantees that lexicographically largest index be used for update when duplicate entries exist.tf.image.random_crop(image, [height, width])
is nowtf.random_crop(image, [height, width, depth])
, andtf.random_crop
works for any rank (not just 3-D images). The C++RandomCrop
op has been replaced with pure Python.- Renamed
tf.test.GetTempDir
andtf.test.IsBuiltWithCuda
totf.test.get_temp_dir
andtf.test.is_built_with_cuda
for PEP-8 compatibility. parse_example
's interface has changed, the old interface is accessible inlegacy_parse_example
(same for related functions).- New
Variable
s are not added to the same collection several times even if a list with duplicates is passed to the constructor. - The Python API will now properly set the
list
member ofAttrValue
in constructedGraphDef
messages for empty lists. The serialization of some graphs will change, but the change is both forwards and backwards compatible. It will break tests that compare a generatedGraphDef
to a golden serializedGraphDef
(which is discouraged).

-
Python 3.3+ support via changes to python codebase and ability to specify python version via ./configure.
-
Some improvements to GPU performance and memory usage: convnet benchmarks roughly equivalent with native cudnn v2 performance. Improvements mostly due to moving to 32-bit indices, faster shuffling kernels. More improvements to come in later releases.
-
Lots of fixes to documentation and tutorials, many contributed by the public.
-
271 closed issues on github issues.
tf.nn.fixed_unigram_candidate_sampler
changed its default 'distortion' attribute from 0.0 to 1.0. This was a bug in the original release that is now fixed.
Initial release of TensorFlow.
