NameError: "Could not cache non-existence of file." in "Ungraded Lab - Introduction to Weaviate API"

Here is the code:

Welcome to DeepLearning.ai and thank you for reporting this issue. I have checked and confirmed that you can safely ignore this, the rest of the lab will work. We’ll try to make an update to remove that error so future learners don’t see it and become concerned.

Error 30: Read-only file system" occurs because the metadata has been downloaded and provided in a folder instead of direct download, preventing any data from being written, modified, or deleted.

kernel detects file system corruption or hardware errors and flips the system to “Read-Only” mode to protect your data from being permanently ruined. So ignore the error as it is ready only error.
