1.1 Recent Version Releases:

The current version of this repository is v2.19.0

1.2 Version Information:

Released on March 5, 2025, TensorFlow version 2.19.0 introduces breaking changes to the tf.lite API, including the deprecation of tf.lite.Interpreter in favor of ai_edge_litert.interpreter and changes to certain C++ constants for better API compatibility. Key updates also include runtime support for the bfloat16 data type in the tfl.Cast operation and the discontinuation of standalone libtensorflow package publishing, while still allowing unpacking from PyPI.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

1. [GPU][BiasAdd] Kernel launch count overflow with large Dense/bias_add (negative work_element_count → abort): This issue reports a bug in TensorFlow 2.20.0 where the GPU kernel launch count overflows during a BiasAdd operation on very large tensors, causing a fatal check failure due to a negative work_element_count. The problem occurs with both Keras Dense layers using bias and raw tf.nn.bias_add calls when using bfloat16 data type on tensors with billions of elements, leading to crashes in eager execution and potentially under XLA compilation or SavedModel workflows.

   • A user confirmed reproducing the bug on Colab with TensorFlow 2.20.0 and GPU enabled, providing a reference notebook to demonstrate the issue.
   • Number of comments this week: 1

2. TensorFlow/Keras model accumulates system and GPU RAM during training: This issue describes a problem where training a TensorFlow/Keras model causes both system RAM and GPU RAM usage to continuously increase, eventually exhausting memory and terminating the training process. The user is employing TensorFlow 2.19.0 with a custom data generator and a custom embedding loss function, and is unsure why the memory accumulation occurs during training.

   • The single comment suggests trying alternative memory allocators such as jemalloc or TCmalloc by preloading them before running the training script, aiming to address potential memory management issues causing the RAM buildup.
   • Number of comments this week: 1

3. Note and Clarify the Error Raised in tf.raw_ops.ExtractGlimpse() and tf.raw_ops.ExtractGlimpseV2(): This issue addresses a documentation bug in TensorFlow's tf.raw_ops.ExtractGlimpse() and tf.raw_ops.ExtractGlimpseV2() functions, specifically clarifying the error message related to the simultaneous specification of uniform_noise and noise parameters. The current error description is misleading because it does not accurately reflect the condition under which the error is raised, and the issue requests that this clarification be added to the docstrings of both functions.

   • A pull request has been opened to fix the documentation and clarify the error message as discussed in the issue.
   • Number of comments this week: 1

4. Clarify the Error Raised in tf.train.CheckpointManager(): This issue addresses a documentation bug in the TensorFlow API where the error raised by tf.train.CheckpointManager() when checkpoint_interval is set without providing a step_counter is not clearly documented. The reporter demonstrates that the current docstring lacks information about this required parameter, which leads to a ValueError during usage, and suggests that the documentation should explicitly mention this condition.

   • A pull request has been opened to address the documentation gap highlighted in the issue, aiming to clarify the error conditions related to the step_counter parameter in tf.train.CheckpointManager().
   • Number of comments this week: 1

5. Clarify the range of action of select_cols in tf.io.decode_csv() and tf.raw_ops.DecodeCSV(): This issue concerns a documentation bug in TensorFlow's tf.io.decode_csv() and tf.raw_ops.DecodeCSV() functions, specifically regarding the unclear behavior and range of the select_cols parameter. The reporter highlights that select_cols appears to only apply to the records argument and not to record_defaults, which is not documented, causing confusion and a ValueError when their lengths do not match.

   • A pull request has been opened to address the documentation clarification, indicating that the issue is being actively worked on and the confusion around select_cols usage is being resolved.
   • Number of comments this week: 1

2.2 Top 5 Stale Issues:

We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.

1. TF-TRT Warning: Could not find TensorRT: This issue describes a problem where TensorFlow on Ubuntu 22.04 cannot detect TensorRT, resulting in a warning message "TF-TRT Warning: Could not find TensorRT" despite having compatible NVIDIA drivers and CUDA versions installed. The user reports difficulties with driver versions, specifically needing to downgrade from the default 550 driver to 535 for their RTX 3050 Ti GPU, and has tried reinstalling TensorFlow multiple times without success, seeking assistance to resolve the TensorRT detection failure.
2. SystemError in tf.ensure_shape and tf.compat.v1.ensure_shape when dtype of shape is tf.uint64 and its value is too large.: This issue reports a bug in TensorFlow where using tf.ensure_shape or tf.compat.v1.ensure_shape with a shape tensor of type tf.uint64 containing very large values close to 2^64 causes a SystemError and OverflowError. Specifically, when a shape like [18446743219011059112, 1] is passed in eager execution mode, the APIs fail with a SystemError related to the built-in isinstance function, indicating improper handling of large unsigned 64-bit integers.
3. Feature Request: Integrate different Digital Signal Processing into tf.signal: This issue is a feature request proposing the integration of advanced digital signal processing (DSP) functionalities, similar to those found in the PyTorch julius library, into TensorFlow's tf.signal module. The requester highlights the benefits of having native audio data augmentation tools within TensorFlow to improve model robustness and streamline workflows by reducing reliance on external libraries.
4. [DOCS] Missing complex input for Round op: This issue reports a documentation bug in TensorFlow where the Round operation is described as supporting complex tensor inputs, but in practice, attempting to use a complex tensor with this operation results in an error, requiring users to round the real and imaginary parts separately. The user provides a reproducible example and error logs showing that the operation fails due to a missing device kernel for complex inputs, highlighting a discrepancy between the official documentation and the actual behavior in TensorFlow version 2.15.0.
5. tf.raw_ops.Unbatch aborts with "Check failed: d < dims()": This issue reports a bug in TensorFlow version 2.17 where the operation tf.raw_ops.Unbatch aborts with a fatal check failure error "Check failed: d < dims()". The user has reproduced this problem on Linux Ubuntu 20.04.3 using Python 3.11.8 with custom code, and the error occurs due to an invalid dimension check during the unbatching process, causing the program to crash.
