Demo test failed due to `OSError: read-only filesystem` about federated-compute HOT 3 CLOSED

It's unclear to me why you would have permission issue, since the path being written to seems to be /usr/local/google/home/ryangu/venv/lib/python3.10/site-packages/tensorflow_federated/data, which seems to be in your home directory and so presumably should be writable to you.

Could you try and inspect the permissions on each of the directories in that path, to see if somehow the permissions are misconfigured on any of them, preventing you from writing to them? E.g. you could use namei -l /usr/local/google/home/ryangu/venv/lib/python3.10/site-packages/tensorflow_federated/data/ to print out the permissions for each directory in that path.

Thanks @timonvo, here is the output:

I think I see what the problem is, so my role (ryangu) only has the group permission instead of owner permission. I am not sure why my cloudtop doesn't have root access though. Happy to discuss with you internally.

I changed the project root directory from ~/Desktop to ~/ and the error just went away. The error means you have no write access to the directory, but I am not sure exactly what's the root cause of my case.
