Couldn't find collections.abc

[fischerdom]

Hey man,

I am not sure if I did something wrong on my Ubuntu-Server, but I had to add import collections.abc to the file .../pyphi/models/cuts.py.

Cheers, Dominik

Hey Dominik!

That's strange. What Python version are you using, and what version of PyPhi? And were you doing anything in particular when the error came up, or just import pyphi?

[fischerdom]

Yes, sounds strange to me, too. I am using Python 3.4. i just used my common phi calculations for Markov brains.

All the tests on Travis are passing for Python 3.4, 3.5, and 3.6 so it's probably something specific to your system, though I have no guess as to why, because this shouldn't be system-dependent.

Do you know which line is throwing the error? Is it the line where you import pyphi or something else?

And which version of PyPhi are you using?

Seems related to https://bugs.python.org/issue20784#msg213126. Also see https://hg.python.org/cpython/rev/d575398d1916. Not sure whether this applies to some 3.4 minor releases and not others, but I think the easy fix is to just use collections.Sequence instead of collections.abc.Sequence.

669f1b5 should fix this. I'm closing this issue now - @fischerdom, can you reopen if it is still an issue?

Alright, thanks for your help!
