How to resolve unresolved reference issues in PyCharm?

When unresolved reference issues arise in PyCharm, it is usually due to the project’s dependencies not being properly installed or configured. Here are some methods to solve this problem:

1. Ensure that all dependencies are properly installed. Missing libraries can be installed using the pip command. If using a virtual environment, make sure it is activated and install dependencies in the correct environment.
2. If the dependencies are correctly installed but PyCharm still cannot resolve the references, you can try clicking on the “File” menu in the bottom right corner of PyCharm and selecting the “Invalidate Caches/Restart” option. Then restart PyCharm, this will clear the cache and rebuild the index, sometimes fixing the resolution issue.
3. Ensure that the interpreter for the project is correctly configured. You can check the project’s interpreter settings in PyCharm’s “Settings” to make sure the correct interpreter has been selected. If using a virtual environment, ensure that it has been correctly configured.
4. If the above methods are not effective, you can try reimporting the project. Click the “File” menu in PyCharm, select “Open”, and then choose the project folder to reimport the project.
5. If the issue persists, try updating PyCharm to the latest version or using another IDE to open the project to determine if the issue is with PyCharm itself.

I hope the methods above can help you resolve the unresolved citation issue.
