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

If the Pycharm console or debugger are showing "Could not find or load the Qt platform plugin windows", the Python EXE file may be located at a different location for the PyCharm interpreter. You might manually select it in File -> Settings -> Interpreter.

1. Set the working directory: File -> Settings -> Build, Execution, Deployment -> Console -> Python Console -> Working directory. Set it to the parent directory where your all code exists.

2. Open Control Panel -> System Settings -> Advanced System Settings -> Environment Variables -> New. Set the variable name QT_PLUGIN_PATH , Variable Directory: Users\\Appdata\Local\Continuum\Anaconda2\Library\plugins.

3. Restart Pycharm.
