How to fix “could not find or load the Qt platform plugin windows” while using Matplotlib in PyCharm

Question

I am getting the error \"could not find or load the Qt platform plugin windows\" while using matplotlib in PyCharm.

How can I solve this?

Answer 1

Copy the folder

\Anaconda3\Library\plugins\platforms

to

\$\

where $ is your project interpreter folder. For example:

"\project\anaconda_env\Scripts\"

because PyCharm calls the python.exe in this folder, not the one in \Anaconda3.
