I found a similar discussion and issue related to the error you're encountering:

  1. Document stuck in queue - "poetry run flask db upgrade" command returned "None of PyTorch, TensorFlow >= 2.0, or Flax have been found" - This discussion is unsolved and was last updated on October 21, 2024 [1].

  2. Upgrade with docker-compose, execute database migration, PyTorch, TensorFlow >= 2.0, or flex not found. - This issue is closed. The suggested solution involves modifying your Dockerfile or Docker Compose setup to ensure that PyTorch, TensorFlow, and Flax are installed. You can add installation commands for these libraries in your Dockerfile or include them in your requirements.txt file [2].

To resolve the issue, you can try the following steps:

  • Dockerfile Adjustments: Add installation commands for PyTorch, TensorFlow, and Flax in your Dockerfile. For example:

    FROM python:3.8
RUN pip install torch==1.8.1 tensorflow>=2.0 flax

  • Requirements File: If using a requirements.txt, add the necessary libraries:

    torch==1.8.1
tensorflow>=2.0
flax

  • Docker Compose: Ensure the service responsible for the migration has access to an environment with these libraries installed.

After making these changes, rebuild your Docker images and run the containers again. This should help resolve the issue with the missing libraries.

This is not the root cause of the problem.

None of PyTorch, TensorFlow >= 2.0, or Flax have been found. Models won't be available and only tokenizers, configuration and file/data utilities can be used.

This is just a warning message, the problem is that you can not locate the migration file, please clean up the database and recreate the containers or upgrade to a higher version, this happens when you try to downgrade the version.

Hi! I´ve found the root of the problem here. I changed a docker compose file configuration and now it´s working properly.

Hi! I wonder how to solve this problem, could you specify what needs to be changed in the docker compose file?

I am also facing the same problem. Please share the changes you made to docker compose file so that we can learn from it. Thanks in advance.
