🚀 QuickStart

• Install conda environment:

conda env create -f flipsketch.yml

• Download T2V LoRA Model from HuggingFace

git lfs install
git clone https://huggingface.co/Hmrishav/t2v_sketch-lora

• Place LoRA checkpoint under root folder:

mv t2v_sketch-lora/checkpoint-2500 ./checkpoint-2500/

• Run app

python app.py

⚡ PyTorch 2+ Support:

To use the codebase with PyTorch2.0, modify here to import from text2vid_torch2.py instead of text2vid_modded.py

💡 How it works?

We use a T2V model fine-tuned on sketch animations, and condition it to follow an input sketch.

We perform attention composition with reference noise from the input sketch.
