I recently upgraded to python 3.9. I can’t launch my experiment anymore. It says its running under stdout:
But I do not see the experiment. This is true even if my experiment has nothing but a ‘Hello World!’ textbox.
Do you know if things have changed with respect to python3.9? But more importantly, where can I see the reason why. No errors reported, a clean run but no window with the text.
OS (e.g. Win10): mac sierra
PsychoPy version (e.g. 1.84.x): don’t know
Standard Standalone? (y/n) If not then what?: custom built
