'jax.experimental.maps' import error

[MikeMpapa]

Hi I am trying to use the levanter image but I get the following error: ModuleNotFoundError: No module named 'jax.experimental.maps'.

Was the model renamed? It worked fine yesterday

Thanks!

I recently hit this error too on a separate problem.

I think that jax just removed maps from experimental recently. That has been deprecated for a while https://github.com/google/jax/blob/5e418f5ab2692d4791816e85ed82eb0834a579cb/CHANGELOG.md?plain=1#L284

Problem:
This problem is from the Haliax package: see here, thread_resource has moved into jax.experimental.mesh_utils.py with recent refactoring. They need to change that.

Solution:
You can fork Haliax repo yourself, fix the importation problem and replace the Haliax link in the said docker image here with link to your yours.

Code seem fixed in halix. Thanks @HMUNACHI for the answer.
