RuntimeError: optional has no value

Hi, I got 'RuntimeError: optional has no value' when executing 'key=random.PRNGKey(0)'. How can i fix the issue? Thanks
version: jaxlib==0.1.62+cuda112

Thanks for the report!

Hmm, I don't think we've seen this one before, and it's a pretty low-level error. I think the best first step is to update your jaxlib installation, from 0.1.62 to the pypi-current 0.1.64. I think this might work:

pip install --upgrade jaxlib==0.1.64+cuda112 -f https://storage.googleapis.com/jax-releases/jax_releases.html

I seem to be getting this error as well! Will try the upgrade.
