The rules tell me that I'm not allowed to ask for clarification about another answer, so I'm going to ask it as a new question about the answer from aaron about this question
I am exploring geometric algebra, in part by using the galgebra python module within a Jupyter Notebook. I just used brew on a macintosh to upgrade everything after spending about 6 months away from the project. Now, I too am getting this:
[I 09:03:00.955 NotebookApp] Jupyter Notebook 6.5.3 is running at:
[I 09:03:00.955 NotebookApp] http://localhost:8888/?token=65925ad35578737dc3d3d0c2d95308fc6f543c915080747d
[I 09:03:00.955 NotebookApp] or http://127.0.0.1:8888/?token=65925ad35578737dc3d3d0c2d95308fc6f543c915080747d
[I 09:03:00.955 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

To access the notebook, open this file in a browser:
file:///Users/norman/Library/Jupyter/runtime/nbserver-34540-open.html
Or copy and paste one of these URLs:
http://localhost:8888/?token=65925ad35578737dc3d3d0c2d95308fc6f543c915080747d
or http://127.0.0.1:8888/?token=65925ad35578737dc3d3d0c2d95308fc6f543c915080747d

Based on the previous answer, I suppose I can just ignore the error messages. But suppose I did want to follow aaron's advice? He advises that I place the following somewhere:
PYDEVD_DISABLE_FILE_VALIDATION=1 jupyter-lab
Does that text go in some file somewhere? What file? Where? Sorry for such a basic question, but I am about 3 levels of indirection away from what I am actually trying to do. It's the old problem of wanting a house, but you have to build the house, which means you need a hammer, but you have to build the hammer... It looks like others are similarly frustrated by answers that assume we know how to muck about in the bowels of the python interpreter.
I typed jupyter notebook
and got the result show above (and now I'm trying to exceed the 20 character minimum)...
