Install Errors¶
Note
These are some misconfiguration errors I came across during testing on Ubuntu. If you have trouble installing, please create an issue.
_tkinter not installed¶
On ubuntu, you may need to install the python3-tk package to use the
tkinter parts of matplotlib.
ImportError: cannot import name ‘multiarray’¶
If you have versions of numpy or matplotlib that were installed on different minor versions of python, you may need to reinstall both.
python -m pip uninstall -y numpy matplotlib
python -m pip install --user numpy matplotlib
