tensorflow/tensorflow最新发布版本:v2.17.0(2024-07-12 00:28:57)
Release 2.17.0
TensorFlow
Breaking Changes
- GPU
- Support for NVIDIA GPUs with compute capability 5.x (Maxwell generation) has been removed from TF binary distributions (Python wheels).
Major Features and Improvements
-
Add
is_cpu_target_available
, which indicates whether or not TensorFlow was built with support for a given CPU target. This can be useful for skipping target-specific tests if a target is not supported. -
tf.data
- Support
data.experimental.distribued_save
.distribued_save
uses tf.data service (https://www.tensorflow.org/api_docs/python/tf/data/experimental/service) to write distributed dataset snapshots. The call is non-blocking and returns without waiting for the snapshot to finish. Settingwait=True
totf.data.Dataset.load
allows the snapshots to be read while they are being written.
- Support
Bug Fixes and Other Changes
-
GPU
- Support for NVIDIA GPUs with compute capability 8.9 (e.g. L4 & L40) has been added to TF binary distributions (Python wheels).
-
Replace
DebuggerOptions
of TensorFlow Quantizer, and migrate toDebuggerConfig
of StableHLO Quantizer. -
Add TensorFlow to StableHLO converter to TensorFlow pip package.
-
TensorRT support: this is the last release supporting TensorRT. It will be removed in the next release.
-
NumPy 2.0 support: TensorFlow is going to support NumPy 2.0 in the next release. It may break some edge cases of TensorFlow API usage.
-
tf.lite
- Quantization for
FullyConnected
layer is switched from per-tensor to per-channel scales for dynamic range quantization use case (float32
inputs / outputs andint8
weights). The change enables new quantization schema globally in the converter and inference engine. The new behaviour can be disabled via experimental flagconverter._experimental_disable_per_channel_quantization_for_dense_layers = True
. - C API:
- The experimental
TfLiteRegistrationExternal
type has been renamed asTfLiteOperator
, and likewise for the corresponding API functions.
- The experimental
- The Python TF Lite Interpreter bindings now have an option
experimental_default_delegate_latest_features
to enable all default delegate features. - Flatbuffer version update:
-
GetTemporaryPointer()
bug fixed.
-
- Quantization for
-
tf.data
- Add
wait
totf.data.Dataset.load
. IfTrue
, for snapshots written withdistributed_save
, it reads the snapshot while it is being written. For snapshots written with regularsave
, it waits for the snapshot until it's finished. The default isFalse
for backward compatibility. Users ofdistributed_save
are recommended to set it toTrue
.
- Add
-
tf.tpu.experimental.embedding.TPUEmbeddingV2
- Add
compute_sparse_core_stats
for sparse core users to profile the data with this API to get themax_ids
andmax_unique_ids
. These numbers will be needed to configure the sparse core embedding mid level api. - Remove the
preprocess_features
method since that's no longer needed.
- Add
