How to resolve modules not found in PyCharm?

There are several ways to solve the problem of not finding a module in PyCharm.

1. Check if the module is installed: Make sure you have correctly installed the necessary module. You can use the pip command to install it, for example, pip install module name.
2. Check Python interpreter settings: Make sure you are using the correct Python interpreter in PyCharm. You can check and change the Python interpreter in PyCharm’s project settings.
3. Refresh interpreter path: In PyCharm’s project settings, click on “Python Interpreter”, then click on the settings icon in the top right corner, select “Show All”, and finally click on the refresh button next to the interpreter path.
4. Check the project structure to ensure it is set up correctly and that module files are in the correct location. You can review and adjust the project structure in the project settings of PyCharm.
5. Clear cache and restart: in PyCharm, click on the “File” menu, select the “Invalidate Caches / Restart” option, and then restart PyCharm.
6. Check your import statements: Make sure you are using import statements correctly in your code and spell the module names correctly. For example, if you want to import the math module, you should use import math, not import mat.

If the above methods still do not solve the problem, it may be due to other configuration or environmental issues. You can search for and consult relevant documents or seek help in the development community.
