RuntimeWarning: os.fork() was called. os.fork() is incompatible with multithreaded code, and JAX is multithreaded, so this will likely lead to a deadlock.

Describe the bug

Running jax and clearml in the same process, I get

/home/tom/miniforge3/envs/tomrl/lib/python3.10/site-packages/clearml/utilities/process/mp.py:629: RuntimeWarning:

os.fork() was called. os.fork() is incompatible with multithreaded code, and JAX is multithreaded, so this will likely lead to a deadlock.

I haven't yet got it to run far enough to see if there's indeed a deadlock. Curious if anyone has seen this before.

Hi @c0g,

You can try setting sdk.development.report_use_subprocess: false in your clearml.conf file and see if it helps
