jupyter notebook shows error message for matplotlib Bad key “text.kerning_factor”

问题

import pandas as pd 
import numpy as np
import matplotlib.pyplot as plt

Bad key "text.kerning_factor" on line 4 in /home/samyak/anaconda3/lib/python3.7/site-packages/matplotlib/mpl-data/stylelib/_classic_test_patch.mplstyle. You probably need to get an updated matplotlibrc file from https://github.com/matplotlib/matplotlib/blob/v3.1.3/matplotlibrc.template or from the matplotlib source distribution

回答1:

It seems to be the case that one of style config files is for matplotlib 3.1 despite that 3.2 is installed.

1. Go to /home/samyak/anaconda3/lib/python3.7/site-packages/matplotlib/mpl-data/stylelib/

2. open _classic_test_patch.mplstyle and comment out the line of text.kerning_factor:6

It worked for me.

回答2:

I encountered the same issue today (using version 3.2.1).

My solution: Reinstall matplotlib :)

回答3:

I had the same problem and I solved it by upgrading Matplotlib using the code:

conda upgrade matplotlib

or

pip install --upgrade matplotlib

回答4:

I also encountered the same problem. Reinstalling matplotlib didn't work for me. I downgraded matplotlib to version 2 using:

conda install matplotlib=2

It worked. Hope this helps.
