Keras 3.3.0

Keras 3.3.0

on Python PyPI

What's Changed

• Introduce float8 training.
• Add LoRA to ConvND layers.
• Add keras.ops.ctc_decode for JAX and TensorFlow.
• Add keras.ops.vectorize, keras.ops.select.
• Add keras.ops.image.rgb_to_grayscale.
• Add keras.losses.Tversky loss.
• Add full bincount and digitize sparse support.
• Models and layers now return owned metrics recursively.
• Add pickling support for Keras models. Note that pickling is not recommended, prefer using Keras saving APIs.
• Bug fixes and performance improvements.

In addition, the codebase structure has evolved:

• All source files are now in keras/src/.
• All API files are now in keras/api/.
• The codebase structure stays unchanged when building the Keras pip package. This means you can pip install Keras directly from the GitHub sources.
