This error occurs because the author did not fix the versions of the dependences used in requirements.txt to those which were current when textplot was written. As such, when installing, the latest version of each module is installed, and since scipy has been updated with breaking API-changes--specifically, the comb module has been moved to scipy.special location--textplot now fails to run out of the box.

As of July 2023, and perhaps surprisingly, this is the only dependency which has broken, and it can be easily fixed by changing line 8 of matrix.py to from scipy.special import comb.
