33
- - [02/08/2023] [Colab demo](https://colab.research.google.com/github/showlab/Tune-A-Video/blob/main/notebooks/Tune-A-Video.ipynb) released!
34
- - [02/03/2023] Pre-trained Tune-A-Video models are available on [Hugging Face Library](https://huggingface.co/Tune-A-Video-library)!
35
- - [01/28/2023] New Feature: tune a video on personalized [DreamBooth](https://dreambooth.github.io/) models.
36
- - [01/28/2023] Code released!
37
-
38
- ## Setup
39
-
40
- ### Requirements
41
-
42
- ```shell
43
- pip install -r requirements.txt
44
- ```
45
-
46
- Installing [xformers](https://github.com/facebookresearch/xformers) is highly recommended for more efficiency and speed on GPUs.
47
- To enable xformers, set `enable_xformers_memory_efficient_attention=True` (default).
48
-
49
- ### Weights
50
-
51
- **[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), [Redshift](https://huggingface.co/nitrosocke/redshift-diffusion), etc.).
52
-
53
- **[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).
54
-
55
-
56
- ## Usage
57
-
58
- ### Training
59
-
60
- To fine-tune the text-to-image diffusion models for text-to-video generation, run this command:
61
-
62
- ```bash
63
- accelerate launch train_tuneavideo.py --config="configs/man-skiing.yaml"
64
- ```
65
-
66
- Note: Tuning a 24-frame video usually takes `300~500` steps, about `10~15` minutes using one A100 GPU.
67
- Reduce `n_sample_frames` if your GPU memory is limited.
68
-
69
- ### Inference
70
-
71
- Once the training is done, run inference:
72
-
73
- ```python
74
- from tuneavideo.pipelines.pipeline_tuneavideo import TuneAVideoPipeline
75
- from tuneavideo.models.unet import UNet3DConditionModel
76
- from tuneavideo.util import save_videos_grid
77
- import torch
78
-
79
- pretrained_model_path = "./checkpoints/stable-diffusion-v1-4"
80
- my_model_path = "./outputs/man-skiing"
81
- unet = UNet3DConditionModel.from_pretrained(my_model_path, subfolder='unet', torch_dtype=torch.float16).to('cuda')
82
- pipe = TuneAVideoPipeline.from_pretrained(pretrained_model_path, unet=unet, torch_dtype=torch.float16).to("cuda")
83
- pipe.enable_xformers_memory_efficient_attention()
84
- pipe.enable_vae_slicing()
85
-
86
- prompt = "spider man is skiing"
87
- ddim_inv_latent = torch.load(f"{my_model_path}/inv_latents/ddim_latent-500.pt").to(torch.float16)
88
- video = pipe(prompt, latents=ddim_inv_latent, video_length=24, height=512, width=512, num_inference_steps=50, guidance_scale=12.5).videos
89
-
90
- save_videos_grid(video, f"./{prompt}.gif")
91
- ```

33
- - [02/08/2023] [Colab demo](https://colab.research.google.com/github/showlab/Tune-A-Video/blob/main/notebooks/Tune-A-Video.ipynb) released!
34
- - [02/03/2023] Pre-trained Tune-A-Video models are available on [Hugging Face Library](https://huggingface.co/Tune-A-Video-library)!
35
- - [01/28/2023] New Feature: tune a video on personalized [DreamBooth](https://dreambooth.github.io/) models.
36
- - [01/28/2023] Code released!
37
-
38
- ## Setup
39
-
40
- ### Requirements
41
-
42
- ```shell
43
- pip install -r requirements.txt
44
- ```
45
-
46
- Installing [xformers](https://github.com/facebookresearch/xformers) is highly recommended for more efficiency and speed on GPUs.
47
- To enable xformers, set `enable_xformers_memory_efficient_attention=True` (default).
48
-
49
- ### Weights
50
-
51
- **[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), [Redshift](https://huggingface.co/nitrosocke/redshift-diffusion), etc.).
52
-
53
- **[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).
54
-
55
-
56
- ## Usage
57
-
58
- ### Training
59
-
60
- To fine-tune the text-to-image diffusion models for text-to-video generation, run this command:
61
-
62
- ```bash
63
- accelerate launch train_tuneavideo.py --config="configs/man-skiing.yaml"
64
- ```
65
-
66
- Note: Tuning a 24-frame video usually takes `300~500` steps, about `10~15` minutes using one A100 GPU.
67
- Reduce `n_sample_frames` if your GPU memory is limited.
68
-
69
- ### Inference
70
-
71
- Once the training is done, run inference:
72
-
73
- ```python
74
- from tuneavideo.pipelines.pipeline_tuneavideo import TuneAVideoPipeline
75
- from tuneavideo.models.unet import UNet3DConditionModel
76
- from tuneavideo.util import save_videos_grid
77
- import torch
78
-
79
- pretrained_model_path = "./checkpoints/stable-diffusion-v1-4"
80
- my_model_path = "./outputs/man-skiing"
81
- unet = UNet3DConditionModel.from_pretrained(my_model_path, subfolder='unet', torch_dtype=torch.float16).to('cuda')
82
- pipe = TuneAVideoPipeline.from_pretrained(pretrained_model_path, unet=unet, torch_dtype=torch.float16).to("cuda")
83
- pipe.enable_xformers_memory_efficient_attention()
84
- pipe.enable_vae_slicing()
85
-
86
- prompt = "spider man is skiing"
87
- ddim_inv_latent = torch.load(f"{my_model_path}/inv_latents/ddim_latent-500.pt").to(torch.float16)
88
- video = pipe(prompt, latents=ddim_inv_latent, video_length=24, height=512, width=512, num_inference_steps=50, guidance_scale=12.5).videos
89
-
90
- save_videos_grid(video, f"./{prompt}.gif")
91
- ```
