New comment by dkwo on void-packages repository https://github.com/void-linux/void-packages/pull/34030#issuecomment-984820811 Comment: Thanks. If I do that, and use 'jupyter lab', then it gives Traceback (most recent call last): File "/usr/lib/sage-9.5.beta7/local/var/lib/sage/venv-python3.9.7/bin/sage-config", line 5, in from sage_conf import _main ModuleNotFoundError: No module named 'sage_conf' /usr/bin/python3: Error while finding module specification for 'sage.repl.ipython_kernel' (ModuleNotFoundError: No module named 'sage') Does it work smoothly for you?
