Hi,
After my ubuntu upgraded nest. Whenever I run a program it does not seems to identify the
nest module. For example, running the twoneuron.py example gives:
Traceback (most recent call last):
File "twoneurons.py", line 43, in <module>
import nest.voltage_trace
ModuleNotFoundError: No module named 'nest.voltage_trace'
Please solution for this? I tried remove and reinstalling and did not work. I did not try
building it.
Thanks,
Inton

Hi Steffen,
Thanks for your reply. Sorry for not have answered before, but in my outlook, I did not
see your messages. It came as blank where your message was an attachment and I just saw
them now.
I will try again and let you know if it worked.
Once again thanks a lot for taking a look at it.
Best,
Inton

Hi Steffen,
I have a clean install of ubuntu 20.04.3 LTS and had the same problem that python did not
find the nest module.
I checked with echo $PYTHONPATH, which gives nothing (blank line) and then ran
/usr/bin/nest_vars.sh and still did not work. Just after adding the path manually: export
PYTHONPATH="/usr/lib/python3.8/site-packages" , did it work
Adding the PYTHONPATH to .bash solves the issue. I guess something is not working in
configuring the path. I assume this should be done automatically.
Thanks,
Inton
