## Setup

### Requirements

```shell
pip install -r requirements.txt
```

Installing [xformers](https://github.com/facebookresearch/xformers) is highly recommended for more efficiency and speed on GPUs. 
To enable xformers, set `enable_xformers_memory_efficient_attention=True` (default).

### Weights

**[Stable Diffusion]** [Stable Diffusion](https://arxiv.org/abs/2112.10752) is a latent text-to-image diffusion model capable of generating photo-realistic images given any text input. The pre-trained Stable Diffusion models can be downloaded from Hugging Face (e.g., [Stable Diffusion v1-4](https://huggingface.co/CompVis/stable-diffusion-v1-4), [v2-1](https://huggingface.co/stabilityai/stable-diffusion-2-1)). You can also use fine-tuned Stable Diffusion models trained on different styles (e.g, [Modern Disney](https://huggingface.co/nitrosocke/mo-di-diffusion), [Anything V4.0](https://huggingface.co/andite/anything-v4.0), [Redshift](https://huggingface.co/nitrosocke/redshift-diffusion), etc.).

**[DreamBooth]** [DreamBooth](https://dreambooth.github.io/) is a method to personalize text-to-image models like Stable Diffusion given just a few images (3~5 images) of a subject. Tuning a video on DreamBooth models allows personalized text-to-video generation of a specific subject. There are some public DreamBooth models available on [Hugging Face](https://huggingface.co/sd-dreambooth-library) (e.g., [mr-potato-head](https://huggingface.co/sd-dreambooth-library/mr-potato-head)). You can also train your own DreamBooth model following [this training example](https://github.com/huggingface/diffusers/tree/main/examples/dreambooth). 


## Usage

### Training

To fine-tune the text-to-image diffusion models for text-to-video generation, run this command:

```bash
accelerate launch train_tuneavideo.py --config="configs/man-skiing.yaml"
```

Note: Tuning a 24-frame video usually takes `300~500` steps, about `10~15` minutes using one A100 GPU. 
Reduce `n_sample_frames` if your GPU memory is limited.

### Inference

Once the training is done, run inference:

```python
from tuneavideo.pipelines.pipeline_tuneavideo import TuneAVideoPipeline
from tuneavideo.models.unet import UNet3DConditionModel
from tuneavideo.util import save_videos_grid
import torch

pretrained_model_path = "./checkpoints/stable-diffusion-v1-4"
my_model_path = "./outputs/man-skiing"
unet = UNet3DConditionModel.from_pretrained(my_model_path, subfolder='unet', torch_dtype=torch.float16).to('cuda')
pipe = TuneAVideoPipeline.from_pretrained(pretrained_model_path, unet=unet, torch_dtype=torch.float16).to("cuda")
pipe.enable_xformers_memory_efficient_attention()
pipe.enable_vae_slicing()

prompt = "spider man is skiing"
ddim_inv_latent = torch.load(f"{my_model_path}/inv_latents/ddim_latent-500.pt").to(torch.float16)
video = pipe(prompt, latents=ddim_inv_latent, video_length=24, height=512, width=512, num_inference_steps=50, guidance_scale=12.5).videos

save_videos_grid(video, f"./{prompt}.gif")
```
