Load checkpoint error #40

Hi! I meet a problems on loading checkpoints.

    ckpt = checkpoints.restore_checkpoint(
  File "/home/wk/anaconda3/envs/copy2/lib/python3.10/site-packages/flax/training/checkpoints.py", line 1129, in restore_checkpoint

    restored = self._restore_with_args(directory, *args, **kwargs)

    restored = self._handler.restore(directory, args=ckpt_args)

ValueError: loop argument must agree with lock

I have found similar issue in the Orbax project,It seems like conflicts between different package versions , but the solution to this issue is to switch the Python version to 3.11, not the project's 3.10. Could you provide the specific version numbers of the packages that need to be installed in this project?

I sincerely look forward to your advice and guidance.

I thought I may solve this problem,just switch the python version from 3.10.0 to 3.10.12.

conda create -n serl python=3.10.12
