PyCharm 2019.1+

There is a new feature called Interpreter in status bar (scroll down a little bit). This makes switching between python interpreters and seeing which version you’re using easier.

Enable status bar

In case you cannot see the status bar, you can easily activate it by running the Find Action command (Ctrl+Shift+A or + +A on mac). Then type status bar and choose View: Status Bar to see it.

This can also happen in Intellij Ultimate, which has PyCharm integrated. The issue is as diagnosed above, you have the wrong interpreter selected.

The exact method to fix this for any given project is to go to Project Settings...Project and adjust the Project SDK. You can add a New Project SDK if you don't have Python 3 added by navigating to the python3 binary. This will fix the errors listed above. A shortcut to Project Settings is the blue checkerboard-type icon.

You can also add Python 3 as the default interpreter for Python projects. On OSX this is in File..Other Settings...Default Project Structure. There you can set the Project SDK which will now apply on each new project. It can be different on other platforms, but still similar.


Go to:

Files -> Settings -> Project -> *"Your Project Name"* -> Project Interpreter

There you can see which external libraries you have installed for python2 and which for python3.

Select the required python version according to your requirements.
