Something I just learned

The TensorFlow that is included in the new frameworks module (aurora_nre_models_frameworks-2025.0.0) was built with numpy==1.26.4 (< 2).

Unfortunately, if you then (for whatever reason) then tries to install / upgrade a package1 that has numpy in its dependencies, e.g.:

python3 -m pip install --upgrade transformers

This will pull in numpy > 2, effectively breaking the frameworks module.

In particular, any application that uses intel/extension_for_pytorch:

import intel_extension_for_pytorch as ipex

Will crash with:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.5 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.
which is obviously frustrating for an application that is only using PyTorch.

Following through the stack trace, I see that the error is actually coming from huggingface/transformers/image_transforms.py#L47.

Digging around a bit more I found there is a flag in transformers that allows you to bypass the entire import tensorflow as tf logic:

USE_TORCH=1

which not only prevents things from crashing with numpy > 2, but is also noticeably quicker.

Reinstall Modules built with numpy < 2

In addition to tensorflow, it seems that: { jax, jaxlib, ml-dtypes, opt-einsum, scipy } were all built with numpy < 2, and so need to be rebuilt after upgrading numpy.

To do so:

python3 -m pip install --upgrade  numpy jax jaxlib ml-dtypes opt-einsum scipy transformers

โœ… Now, weโ€™re able to successfully:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.5 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.
