I would like to use the "base" environment of Anaconda for Pycharm. However, I cannot find this option in the list of conda environments. Where should it be?
At the bottom right of your screen, click on "Python 3.x (myProjectName)" > Add Interpreter.
Click on "Conda environment" > check "Existing Environment" > navigate to wherever you installed Anaconda at > Select the python.exe at the root of Anaconda3 directory. (i.e. ~\Anaconda3\Python.exe).
