        trainingFile: ‘modules/MMM-Facial-Recognition/training.xml’,

        I got a issue when i add the facial module. the Facial-tools work fine, it’s seems like python script issues.

        Could anyone help me with this issue ?

        Whoops! There was an uncaught exception…
        TypeError: PythonShell is not a constructor
        at Class.python_start (/home/csc/MagicMirror/modules/MMM-Facial-Recognition/node_helper.js:11:21)

        at process._tickCallback (internal/process/next_tick.js:61:11)
        MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
        If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

                specify your user labels in the environment with

                export FACE_USERS=Alice,Bob,Casey,Doug

                im not sure what to do with this. do i have to write this in the terminal? because everytime i restart my pi, the facial recognition doesnt recognize my face

                      @naktah after writing the following command in the terminal:

                      python tools.train.py
                      

                      you get some output with the users you have setup (remember the order). Assuming it gives you Alice,Bob,Casey,Doug, then you run this in the terminal:

                      export FACE_USERS=Alice,Bob,Casey,Doug
