Bionic: python3-comedilib module empty

[Anders Montonen]

Ubuntu 18.04.1 on AMD64, python3-comedilib 0.10.2-4build7

The installed module is empty and completely non-functional. The Python 2.7 python-comedilib package appears to be OK.

Hi

I have just tested this with the newest version 0.11.0 but I am sure it is the
same for 0.10.2.

>>> import comedi.comedi as c
>>> c.MAJOR
98
>>>

Hope this solves your problem

Hi Gudjon,

I came across the same issue. That's not the intended way that comedi module should be loaded in Python. You should be able to write just "import comedi as c". Right now, this works fine in Python 2, but not in Python 3.

I think that the problem is that comedi.py (and the .so) should be directly placed in /usr/lib/python3/dist-packages/, not in a subdirectory "comedi/". Was there a specific reason that it was done this way in Python 3?
