Prepare Data & Models

We've prepared some debug data to facilitate development. To make sure the training pipeline is correct, train on the debug data and make sure the model overfit on it (feed it the same text prompt and see if the output video is the same as the training data)

python scripts/download_hf.py --repo_id=Stealths-Video/dummyVid --local_dir=data/dummyVid --repo_type=dataset
python scripts/download_hf.py --repo_id=Stealths-Video/mochi --local_dir=data/mochi --repo_type=model
python scripts/download_hf.py --repo_id=Stealths-Video/Mochi-Synthetic-Data --local_dir=data/Mochi-Synthetic-Data --repo_type=dataset

How to overfit

bash scripts/overfit.sh

Make sure to edit data/Mochi-Synthetic-Data/videos2caption.json such that this is only one video in the dataset (you can copy multiple annotations of the same video). Also make sure to edit the prompt in scripts/overfit.shto match the prompt in the training data. I observe the overfitting after 50 steps.

TODO

Delete all npu related stuff.
Remove inpaint.
Create dummy debug data.
