wav2lip not working for me please help!!!

[zwin55]

i made one great video i was really pleased with, and then the second time i tried to run wav2lip i've been getting the same error over and over....it happens on different computers, and different web browsers too so I don't think i've done anything wrong?

i open the google colab, click "connect" top right and successfully connect to the python 3....

then i press the play button to run step one, i get the warning message, i click run anyway, it goes through its process, and I get a red exclamation point saying it was unsuccessful and the reason why is: ModuleNotFoundError: No module named 'ffmpeg'

from there I obviously cannot get to steps 2 through 4 at all anymore.....please someone, help me fix this!!!
