Further information re pip and python3 problem

[Phil]

After I pressed the "send" key I thought that maybe I have an old
version of pip so I upgraded it and the error message shows that I need
to install the attrdict module which I have done and now I have a new
error message:

      ImportError: cannot import name 'Mapping' from 'collections'
(/usr/lib/python3.10/collections/__init__.py)

My flaky Internet connection has dropped out so I cannot proceed any
further tonight. I might be able to send this e-mail.

This is what Python 3.8 has to say about that issue:

$ py -3.8 -c "from collections import Mapping"
<string>:1: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working

One of your packages needs an upgrade to be compatible with Python 3.10.
Which one it is will probably be apparent from the rest of your traceback, which you didn't include.

Thank you Steve and Anders.

The package for Ubuntu is pretty old Steve, older than the previous
version of WxPython that I had installed with pip.

My Internet connection picked up for awhile and I did read something
about ABC. Here is the complete error message and I have installed
attrdict.

I uninstalled attrdict and instead installed attrdict3 and I see I now
need to install a few more packages. A job for tomorrow, if I have an
Internet connection.
