Hi Enrique,
Are you using a virtual environment as isolation mode? In that case the dependencies of the app are not installed in the viktor-installs folder, but inside the virtual environment. If you are using a virtual environment you can select the project interpreter from the virtual environment folder. After doing this, Pycharm should automatically recognize the installed dependencies that are present in the virtual environment. I will adjust the docs to reflect the correct set up when using a virtual environment.
What is the Python version you are currently using? I have the idea that Pycharm currently doesn’t correctly recognize Python 3.10, which also gives me import errors. When switching to a different Python version I do get correct code completion.
