JSRF Player Animation Importer: Need Help

I recently made ports of 10 Jet Set Radio Future Characters into Source Filmmaker.
I was pointed to this script to try to get the rest of the characters from the game: https://github.com/Gurten/Blender-JSRF-Player-Animation-Importer

I already have some of the steps all set up, but the video on this isn’t clear. I could make out the first step I needed to do, but the second command it shows to enter doesn’t work for me. Not sure if I copied it wrong or the command was changed in the video compared to what I got.
