[MSNoise] MSNoise-Tomo: Problem with iftan

Hei everyone, As I try to run "msnoise p tomo iftan" I receive the error message below. The GUI starts but it does not work. I am using macOS Catalina, Python 3.7 via Anaconda and mysql. Any suggestions are highly appreciated, struggling with this for quite some time.
