Couldn't run python3 gui/application.py It turned out that when using the new version of Dash, the call was replaced with app.run(...) In application.py, I corrected the line from app.run_server(debug=False) to => app.run(debug=False) and managed to run

Yeah, this is what I did so wanted to commit this change and get it merged but looks like that’s not happening.
