finetrainers 🧪

cogvideox-factory was renamed to finetrainers. If you're looking to train CogVideoX or Mochi with the legacy training scripts, please refer to this README instead. Everything in the training/ directory will be eventually moved and supported under finetrainers.

FineTrainers is a work-in-progress library to support training of video models. The first priority is to support lora training for all models in Diffusers, and eventually other methods like controlnets, control-loras, distillation, etc.

News

• 🔥 2024-12-20: Support for LoRA finetuning of Hunyuan Video added! We would like to thank @SHYuanBest for his work on a training script here.
• 🔥 2024-12-18: Support for LoRA finetuning of LTX Video added!

Quickstart

Clone the repository and make sure the requirements are installed: pip install -r requirements.txt and install diffusers from source by pip install git+https://github.com/huggingface/diffusers.

Then download a dataset:

# install `huggingface_hub`
huggingface-cli download \
  --repo-type dataset Wild-Heart/Disney-VideoGeneration-Dataset \
  --local-dir video-dataset-disney

Then launch LoRA fine-tuning. For CogVideoX and Mochi, refer to this and this.

Note: It is recommended to use Pytorch 2.5.1 or above for training. Previous versions can lead to completely black videos, OOM errors, or other issues and are not tested.

If you would like to use a custom dataset, refer to the dataset preparation guide here.

Note

To lower memory requirements:

• Use a DeepSpeed config to launch training (refer to accelerate_configs/deepspeed.yaml as an example).
• Pass --precompute_conditions when launching training.
• Pass --gradient_checkpointing when launching training.
• Do not perform validation/testing. This saves a significant amount of memory, which can be used to focus solely on training if you're on smaller VRAM GPUs.

Memory requirements

Supported and verified memory optimizations for training include:

• CPUOffloadOptimizer from torchao. You can read about its capabilities and limitations here. In short, it allows you to use the CPU for storing trainable parameters and gradients. This results in the optimizer step happening on the CPU, which requires a fast CPU optimizer, such as torch.optim.AdamW(fused=True) or applying torch.compile on the optimizer step. Additionally, it is recommended not to torch.compile your model for training. Gradient clipping and accumulation is not supported yet either.
• Low-bit optimizers from bitsandbytes. TODO: to test and make torchao ones work
• DeepSpeed Zero2: Since we rely on accelerate, follow this guide to configure your accelerate installation to enable training with DeepSpeed Zero2 optimizations.

Important

The memory requirements are reported after running the training/prepare_dataset.py, which converts the videos and captions to latents and embeddings. During training, we directly load the latents and embeddings, and do not require the VAE or the T5 text encoder. However, if you perform validation/testing, these must be loaded and increase the amount of required memory. Not performing validation/testing saves a significant amount of memory, which can be used to focus solely on training if you're on smaller VRAM GPUs.

If you choose to run validation/testing, you can save some memory on lower VRAM GPUs by specifying --enable_model_cpu_offload.

LoRA finetuning

Note

The memory requirements for image-to-video lora finetuning are similar to that of text-to-video on THUDM/CogVideoX-5b, so it hasn't been reported explicitly.

Additionally, to prepare test images for I2V finetuning, you could either generate them on-the-fly by modifying the script, or extract some frames from your training data using: ffmpeg -i input.mp4 -frames:v 1 frame.png, or provide a URL to a valid and accessible image.

Full finetuning

Note

The memory requirements for image-to-video full finetuning are similar to that of text-to-video on THUDM/CogVideoX-5b, so it hasn't been reported explicitly.

Additionally, to prepare test images for I2V finetuning, you could either generate them on-the-fly by modifying the script, or extract some frames from your training data using: ffmpeg -i input.mp4 -frames:v 1 frame.png, or provide a URL to a valid and accessible image.

Note

Trying to run full finetuning without gradient checkpointing OOMs even on an A100 (80 GB), so the memory measurements have not been specified.

Note

• memory_after_validation is indicative of the peak memory required for training. This is because apart from the activations, parameters and gradients stored for training, you also need to load the vae and text encoder in memory and spend some memory to perform inference. In order to reduce total memory required to perform training, one can choose not to perform validation/testing as part of the training script.

• memory_before_validation is the true indicator of the peak memory required for training if you choose to not perform validation/testing.
