AttributeError: module ‘matplotlib. pyplot‘ has no attribute ‘ishold‘

description¶

Error when using matplotlib.pyplot in jupyter notebook to compose a picture

Error: AttributeError: module'matplotlib. pyplot' has no attribute'ishold',

reason¶

This problem may be caused by a mismatch between the networkx and matplotlib versions, or the incorrect installation order of the two.

solution¶

1. uninstall networkx and matplotlib first¶

Open Anaconda Powershell Prompt

pip uninstall --user networkx

Wait until neyworkx is successfully uninstalled, then continue to uninstall matplotlib:

pip uninstall --user matplotlib

2. Install matplotlib and networkx again (note the order)¶

Still executed in Anaconda Powershell Prompt

pip install --user matplotlib

When matplotlib is successfully installed, you will find that it reminds that the networkx version needs to be >=2, which may be the main reason for the previous error.

Continue to install networkx

pip uninstall --user networkx

3 Restart jupyter notebook¶

run your own code and you will find that you can plot again.
