Clone this repo into StepMania/Songs/Generated/generation to start generating stepfiles
To generate steps for songs add them to /stepping_songs and run
python Stepping.py --songs {name}.mp3 {name}.mp3...
If --songs is not specified all songs in /stepping_songs will be stepped
To generate steps with a certain number of steps, jumps etc run
python Stepping.py --class_ammounts {steps} {jumps} {hands} {holds} {rolls} {mines}
where each amount is the fraction of steps that will be of that type eg
python Stepping.py --class_ammounts 0.15 0.04 0.0 0.01 0.0 0.01
To retrain models start by running
python FilterTrainingSongs.py
python ExtractMusicFeatures.py
python ExtractStepfileFeatures.py --target_difficulty {difficulty}
This will create a list of songs to train on from your downloaded packs and then generate some features from the music and stepfile for each song within one difficulty of the target difficulty provided (This takes a long time to run)
ExtractStepfileFeatures.py can be run with --difficulty_adjust {pack}~{adjust} {pack}~{adjust}... if a pack is known to be stepped harder than usual eg --difficulty_adjust Game_Grumps_Revolution~5 GREP~5
You can then run
python TrainNoteClassModel.py
or
python TrainNoteModels.py
Once a model has been retrained, you can run Stepping.py on a song that has already been stepped with --regenerate_note_classes or --regenerate_notes to ignore previously generated steps
