Re: Problem working with Python 3.10

Hi Michael,

Thanks for your response. 

Pip thinks the module is installed -
pip list |grep gpib
gpib              1.0

However your test code gives me an import error -

File "testing.py", line 6, in <module>
    import gpib
ModuleNotFoundError: No module named ‘gpib'

Pip confirms the package is installed in by venv environment 

"Requirement already satisfied: gpib in ./.venv/lib/python3.10/site-packages/gpib-1.0-py3.10-linux-x86_64.egg (1.0)"

Does the python import path have to be set someway to access the GPIB install?

Lin
Regards,
Chris
