Hi Inton,


thank you for your question. I assume you installed nest via the Ubuntu installation system. What version of Ubuntu are you running? With Focal I can reproduce your problem and will look into it.

For an immediate and flexible solution I can recommend you to install from the sources:

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
