JupyterLab Cleaning up site-packages directory

Hello, We have around 20 users using JupyterLab v2.2.8 and the below mentioned directory is eating up around 50GB of space and the system is running into disk space issues. We generally install packages related to Spark or Machine learning.

I suspect the below files/folders which start with “~” sign (tilde) are temporary or created with virtual environments. Will it be safe to delete these files as they take 100s of MBs?

ls /opt/jupyterhub/lib/python3.7/site-packages/

This link suggests these are temp files and safe to delete.
