Argh.

Sure I am!  I'm always happy if people clean up behind me and
watch my steps. ;-)

Thanks a lot for your support

Bug#895531: Unable to import neuron in python3

Control: found -1 7.6.3-3
Control: severity -1 serious

I realised that this bug either remained or we have a regression
in version 7.6.3.  This becomes obvious after I added

  Testsuite: autopkgtest-pkg-python

to the team upload of 7.6.3-3.  I also added debian/salsa-ci.yml
which enables you watching the problem possibly here:

  https://salsa.debian.org/science-team/neuron/-/jobs/3786088

Kind regards
Andreas.

That is good to know! I'll be closing this bug, as the issue is
actually something else and likely intended upstream behavior.
It could be a good idea to contact NEURON upstream directly about
this, as it obviously is quite confusing behavior.

Cheers,
Matthias

i!
Interesting, this works here without problems (vanilla Debian installation):

```
$ python3
Python 3.6.5rc1 (default, Mar 14 2018, 10:54:23)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import neuron
NEURON -- VERSION 7.5 master (6b4c19f) 2017-09-25
Duke, Yale, and the BlueBrain Project -- Copyright 1984-2016
See http://neuron.yale.edu/neuron/credits

>>>
```

The "nrn" module is a built-in module. Do you have any bits of a
different NEURON installation floating around that might interfere
with the package? Could you run the Python interpreter in verbose mode
(python3 -v) and try to import the module again (and paste the
output)? That would help to determine what is different between the
attempts to load the module.

Cheers,
   Matthias
