Error when installing `tf-models-official`

[Jiya873]

Prerequisites

• I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• I am reporting the issue to the correct repository. (Model Garden official directory)
• I checked to make sure that this issue has not been filed already.

1. The entire URL of the file you are using

https://github.com/tensorflow/models/tree/master/official/...

2. Describe the bug

I’m trying to install the tf-models-official package in order to run test files and experiments from the TensorFlow Model Garden on my local system. However, the installation consistently fails due to a subprocess-exited-with-error, specifically caused by an AttributeError: cython_sources.

It appears to happen during the wheel-building process when running pip install tf-models-official. The setup fails when trying to get requirements for building the wheel, and throws warnings related to deprecated license classifiers and then crashes due to the cython_sources error.

This has been a blocker for me trying to use the repo.

3. Steps to reproduce

1. Create a virtual environment:
   python -m venv tf-env

2. Activate it and upgrade pip:
   pip install --upgrade pip setuptools wheel

3. Try to install the official package:
   pip install tf-models-official

4. Observe the crash with the cython_sources error during build.

4. Expected behavior

Expected the package to install successfully so I can import and use modules from official.vision, run test files, and explore models. Instead, the build fails due to what seems like a packaging issue.

5. Additional context

Full error log includes:

error: subprocess-exited-with-error

× Getting requirements to build wheel did not run successfully. │ exit code: 1 ╰─> AttributeError: cython_sources ... Please consider removing the following classifiers in favor of a SPDX license expression: License :: OSI Approved :: MIT License ...

I have tried:

• Upgrading pip, setuptools, and wheel
• Installing directly from GitHub
• Installing with --no-build-isolation
• Installing dependencies from official/requirements.txt

Still encountering the same issue every time.
