My guess is the python intepreter is not loading. Try adding the python directory location to your Windows environment variable named “Path”. Something like explained at [https://geek-university.com/python/add-python-to-the-windows-path/](https://geek-university.com/python/add-python-to-the-windows-path/) ---

First you have to check the system recognoze the python commands, Try, Open a command prompt window (press Windows+R, type in cmd, and hit enter). Just type “python” on the **command line** and see if you get an error or not. If you see a response from a Python interpreter it will include a version number in its initial display. If it shows error, try add [Python path](http://net-informations.com/python/intro/path.htm) in your syste.
