Expected outcome
Matplotlib version
- Operating system:
- Matplotlib version:
- Matplotlib backend (
print(matplotlib.get_backend())): - Python version:
- Jupyter version (if applicable):
- Other libraries:
I'm running jupyter in a docker container
As part of my trial and errors I have repeatedly:
rm -rf ~/.cache/matplotlib/
And I have also:
conda update matplotlib
