Install, uninstall, and upgrade interpreter paths
IntelliJ IDEA makes it possible to add paths to the selected interpreter. These paths will be added to the environment variable PYTHONPATH. Also, IntelliJ IDEA will index these paths and (potentially) resolve the objects of the code (for example, imports of packages).
To view the interpreter paths
Open the Project Structure dialog (for example Ctrl+Alt+Shift+S).
In the Project Structure dialog, click SDKs node under the Platform Settings.
Select the desired interpreter.
View the interpreter paths in the Classpath tab:
