JHub: Should everyone use python = "/wynton/group/jhadmin/base-clone/bin/python"?

[HenrikBengtsson]

On https://wynton.ucsf.edu/hpc/howto/jupyterhub.html, the example shows:

                     # Python for Dask worker to use, visible to the grid nodes
                     python = "/wynton/group/jhadmin/base-clone/bin/python",

Is that just an example, or are all users supposed to use that specify Python executable?

Also,

dev1$ whoami
hb-test

dev1$ ls -l /wynton/group/jhadmin/base-clone/bin/python
ls: cannot access /wynton/group/jhadmin/base-clone/bin/python: Permission denied

dev1$ ls -l /wynton/group/jhadmin/
ls: cannot open directory /wynton/group/jhadmin/: Permission denied

dev1$ stat /wynton/group/jhadmin/

So, is the above example actually working for regular users?

Issue should be fixed. Let me know if you still see an error.
