Attempting to import MatchingMarkets in Google Codelab environment running Python 3.6 however getting the following error:

import matchingmarkets as mm

ImportError Traceback (most recent call last)

ImportError: Cannot load backend 'Qt5Agg' which requires the 'qt5' interactive framework, as 'headless' is currently running

After doing some research on the error, it seems others have had similar error with matplotlib, though it is not clear if the suggested workaround would help in this case.

Any insights would be greatly appreciated.. or alternatively if you happen to have a clean install with MatchingMarkets already working somewhere in an online notebook/environment , please advise where it can be accessed. Thanks.

Some more hints in the README on how to pull in the dependencies and run this would be helpful.

So far this worked for me to avoid import errors:

pip install scipy networkx PyQt5

Then, since I don't see a pyproject.toml or setup.py, I just tried to run python from the root directory of the project, as cloned via git.

But I'm guessing that I'm getting different versions than you are, since I get these errors:

Python 3.8.0 (default, Oct 28 2019, 16:14:01)

It looks like I have networkx version 2.5.
