I encountered an issue while working on exercises for the CS4220 course, specifically right before exercise 1.10. A short example provided just before this exercise includes the following code snippet:
>>> a = pr.gendath()
>>> w = pr.parzenc(a)
>>> pr.scatterd(a)
>>> pr.plotc(w)
However, running this code resulted in the following error:
Traceback (most recent call last):
File "c:\Users\boydc\Projects\university\cs4220-ml1\test.py", line 10, in <module>
pr.plotc(w)
File "C:\Users\boydc\Anaconda3\envs\cs4220-env\lib\site-packages\prtools\mapping.py", line 507, in plotc
colors = next(ax._get_lines.prop_cycler)['color']
AttributeError: '_process_plot_var_args' object has no attribute 'prop_cycler'After some investigation, I discovered that the issue may be related to changes in the latest matplotlib release to facilitate pickling (matplotlib/matplotlib#26831). It appears that this has led to a break in the internal API.
A potential workaround suggested in the linked GitHub issue is to downgrade matplotlib to v3.7, as it seems to resolve the problem. However, I wanted to bring this to your attention as the prtools package is likely to face compatibility issues with matplotlib v3.8+ until the underlying problem is addressed or matplotlib creates a new version that publicly exposes the color cycler for an axis.
Edit: I just observed that a PR (#19) about this issue has already been opened, so feel free to close this issue.
