RuntimeError: dictionary changed size during iteration

[cold-inferno]

• Using spleeter-native
• OS: Macos Catalina 10.15.4
• Ableton 10.1.13
• Max 8.1.3
• Python 3.7.3

Homebrew, Python, FFmpeg and Spleeter all installed correctly as far as i can tell. Checked the install using "python3 check-install.py" got no errors.

Error text in MAX

Error: Command failed: spleeter separate -i "/Users/MyUsername/Downloads/target.mp3" -o "/Users/MyUsername/Music/Ableton/User Library/M4L/spleeter-native" -p spleeter:4stems-16kHz

nb. most likely i've overlooked something, or did something wrong. Though i can't seem to figure out what.

dupe of https://github.com/diracdeltas/spleeter4max/issues/11. no idea why this is happening tbh :(. i'll investigate more and post in the other issue.

ok, i think this is fixable by updating python to 3.7.5 https://github.com/tensorflow/tensorflow/issues/33183#issuecomment-557915426
