1.press Ctrl+Alt+s to open the settings

2.on the left column, select Project Interpreter

3.on the top right there is a list of python binaries found on your system,pick the right one

5.validate

Just in case you are not able to add an other module (that happened to me as well) you can change the project interpreter.
