Hello! I am trying to use Ray Tune to tune hyperparameters for my model deployed on Streamlit Cloud, but I get this error:

Traceback (most recent call last):

PermissionError: [Errno 13] Permission denied: '/tmp/ray'

I’m quite new to this, so I’m not sure if its because I can’t create a temp folder on Streamlit itself or on Github. Thanks for helping! :slight_smile:

Can you share your app link here and we can take a look?

Happy Streamlit-ing!
