<!--To help us understand and resolve your issue, please fill out the form to the best of your ability.--> <!--You can feel free to delete the sections that do not apply.--> ### Problem The attributes mentioned in the issue title are clearly internal and should not be documented (*possibly* unless we explicitly override them, if ever). See e.g. https://matplotlib.org/stable/api/_as_gen/matplotlib.colors.Colormap.html#matplotlib.colors.Colormap.__dict__ https://matplotlib.org/stable/api/_as_gen/matplotlib.colors.Colormap.html#matplotlib.colors.Colormap.__module__ https://matplotlib.org/stable/api/_as_gen/matplotlib.colors.Colormap.html#matplotlib.colors.Colormap.__weakref__ ### Suggested Improvement Suppress these attributes in the docs. **Matplotlib version** * Matplotlib documentation version (is listed under the logo): both 3.4.1 and 3.4.1.post544.
