AttributeError: module 'matplotlib' has no attribute 'pyplot' about matplotlib-inline HOT 2 OPEN

The error seems to be fixed if I explicitly declare import matplotlib.pyplot as plt at the start of the file and then use that to call it like this: plt.close('all'). If that alone is satisfactory, I would request to do a PR.

This, or some variant of it, is the correct fix. Because matplotlib.pyplot is not explicitly imported, it may or may not exist at the time of this call, depending on what previous code did. The simplest change would be:

         if close and Gcf.get_all_fig_managers():
+            import matplotlib.pyplot
             matplotlib.pyplot.close('all')

@QuLogic That suggested fix won't work, as in the original example the matplotlib module was overwritten silently by librosa, due to their implementation of lazy loading. See here for details.

In particular, as long as import matplotlib is present first, adding import matplotlib.pyplot won't work. However, it appears addingimport matplotlib.pyplot as plt does work (for reasons that surpass my mortal understanding).

While I think such an import should be added (as per your fix), the issue is really upstream with librosa, so I've filed an issue there.
