I. News

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 LiteRT (tf.lite) API, including the deprecation of tf.lite.Interpreter in Python with a migration path to ai_edge_litert.interpreter, and updates to C++ constants for better API compatibility. Key improvements include support for the bfloat16 data type in the tfl.Cast operation runtime kernel, alongside the discontinuation of standalone libtensorflow package publishing.

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. TensorFlow was not built with CUDA kernel binaries compatible with compute capability 12.0 CUDA_ERROR_INVALID_HANDLE: This issue reports a bug where TensorFlow was not built with CUDA kernel binaries compatible with the NVIDIA RTX 5080 GPU's compute capability 12.0, causing CUDA kernels to be just-in-time compiled from PTX and resulting in a CUDA_ERROR_INVALID_HANDLE during kernel launch. The user struggles to build TensorFlow from source for CUDA 12.8.1/9.8 due to unsupported GPU architecture errors and seeks advice on resolving these build and runtime compatibility problems.

   • The comments reveal that the issue does not occur with PyTorch and that the problem may stem from incompatible TensorFlow and CUDA versions; attempts to build TensorFlow from source fail due to unsupported architecture errors, but a workaround involving a specific NVIDIA container image was suggested and reported to work for a similar GPU model, though the CUDA_ERROR_INVALID_HANDLE persists for the original user.
   • Number of comments this week: 5

2. tf.keras.Model have not attribute : submodules but the document still use the error attribute: This issue reports a discrepancy between the TensorFlow documentation and the actual API behavior, where the tf.keras.Model class is said to have a submodules attribute, but users encounter an AttributeError indicating that this attribute does not exist. The user demonstrates this problem with a custom model subclass and points out that the guide example uses tf.Module instead of tf.keras.Model, leading to confusion and errors when accessing submodules.

   • The comment clarifies that the documentation example incorrectly uses tf.Module rather than subclassing from tf.keras.Model, which is necessary to have the submodules attribute available. A corrected example subclassing tf.keras.Model is provided, which runs without error and properly exposes the submodules attribute, resolving the confusion.
   • Number of comments this week: 1

3. The model does not have any trainable weights.: This issue reports a documentation bug where a custom TensorFlow Keras model defined with tf.Variable for weights triggers a warning stating that the model does not have any trainable weights. The user demonstrates that replacing tf.Variable with self.add_weight in the model definition resolves the warning and allows training to proceed correctly.

   • The single comment expresses interest in contributing to the issue resolution, indicating a willingness to work on fixing or improving the documentation or example code.
   • Number of comments this week: 1

Since there were fewer than 5 open issues, all of the open issues have been listed above.

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 despite having the appropriate NVIDIA driver (535) and CUDA version (12.4) installed for an RTX 3050 Ti GPU. The user reports persistent errors after multiple reinstallations and driver adjustments, seeking assistance to resolve the TF-TRT warning about the missing TensorRT component.
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 such large values are passed, the functions fail in eager execution mode, triggering an internal error related to type checking, which is unexpected behavior.
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 julius library, into TensorFlow's tf.signal module. The requester highlights the current lack of sophisticated audio data augmentation tools within TensorFlow compared to PyTorch and suggests that adding these capabilities would enhance audio model training by enabling native, efficient preprocessing and augmentation workflows.
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 actual functionality.
5. tf.raw_ops.Unbatch aborts with "Check failed: d < dims()": This issue reports a bug in TensorFlow version 2.17 where the tf.raw_ops.Unbatch operation aborts with a fatal error message "Check failed: d < dims()" when invoked with certain tensor inputs. The problem occurs on Linux Ubuntu 20.04.3 LTS using Python 3.11.8, and the user has provided a minimal reproducible example demonstrating that the operation crashes due to a shape-check failure in the tensor shape code.

2.3 Open Issues

This section lists, groups, and then summarizes issues that were created within the last week in the repository.

Issues Opened This Week: 5

Summarized Issues:

• CUDA compatibility and runtime errors: TensorFlow fails to run CUDA kernel binaries on NVIDIA RTX 5080 GPUs with compute capability 12.0 due to being built without compatible CUDA kernel binaries, causing long JIT compilation times and CUDA errors like CUDA_ERROR_INVALID_HANDLE during kernel launches. This issue highlights the incompatibility between TensorFlow builds and the latest CUDA versions on specific hardware.
• issues/97387

• TensorFlow Keras API attribute errors: The TensorFlow documentation incorrectly references a non-existent submodules attribute on tf.keras.Model instances, leading to AttributeErrors in example code. Additionally, using tf.Variable directly in custom Keras models triggers warnings about missing trainable weights, with the recommended fix being to use self.add_weight instead to properly register parameters.
• issues/97403, issues/97599

• Control flow and operator fusion bugs in Keras: Using tf.no_op as a sequential control mechanism in Keras causes a DAG cycle after operator fusion when splitting matrix multiplications across multiple tf.functions, resulting in cyclic logical graphs and dependency confusion. This bug affects the correct execution order and graph construction in TensorFlow 2.10.0.
• issues/97512

• Module import errors after TensorFlow version downgrade: Downgrading TensorFlow from version 2.19.0 to earlier versions like 2.18.0, 2.17.0, and 2.16.2 fixes some malfunctions but causes a ModuleNotFoundError because the keras module is missing in these older versions, despite expectations that it should be included. This issue complicates version management and backward compatibility.
• issues/97620
