There were two issues encountered on a fresh install to LORA training:

  1. Conflicts in dependency versions made trainer.py unable to load.
  2. torchcodec needed when processing MP3's

Re: (1)

Fixed conflicting versions between diffusers, transformers, and peft, which is caused by having an unspecified version of peft in requirements.txt.

Using the versions installed by requirements.txt, I was able to get through the errors by updating the versions to: diffusers 0.36.0
peft 0.18.0
transformers 4.57.3


Re: (2)

The error message below comes up in LORA training:

TorchCodec is required for load_with_torchcodec. Please install torchcodec to use this function.

To fix it, I simply added torchcodec
