How to Create an AI Video Using Stable Video Diffusion on Colab
Currently, it's recommended to use Colab for cloud deployment to run Stable Video Diffusion. Below is the specific process. After becoming a member, the speed to generate a 4-second video using an A100 graphics card is 53 seconds, while with a T4 graphics card, it's 7 minutes. This information is provided for reference.
First, open the Colab notebook link: Stable Video Diffusion Colab. Then, click on the play icon sequentially to run different cells and configure the environment and model.
Cell 1: Setup Running this cell might show an error, but it doesn't affect the generation. Look for a green checkmark beside the play button to confirm completion.
Cell 2: Colab hack for SVD
Cell 3: Download weights
Cell 4: Load Model
Cell 5: Sampling function
Cell 6: Do the Run! This is the final cell. Upon successful execution, you'll see an address. Clicking this address opens a webpage where you can upload images for generation.
Adjusting advanced options is generally unnecessary. Setting values too high may cause memory issues. Remember, only PNG format is supported. Convert images in other formats to PNG. The generated resolution is 1024x576. Images not in this aspect ratio can be compressed or automatically adjusted to fit this size.
After generating the video, the interface will display the video. Remember to download and save the video.
How to Install Stable Video Diffusion on Your Computer
1. Cloning the Official Repository
Start by cloning the official repository of Stability AI's generative models. Use the following commands in your terminal to clone and navigate into the generative-models directory:
git clone [email protected]:Stability-AI/generative-models.git
cd generative-models
2. Setting Up the Virtual Environment
After successfully cloning the repository and moving into the generative-models root directory, you'll need to set up a virtual environment. This step is crucial for maintaining dependencies and project-specific configurations separate from your global Python setup.
Important Note: The instructions provided are specifically tested and confirmed to work under python3.10. If you are using a different version of Python, you may encounter compatibility issues or version conflicts.
Here's how to set up the virtual environment for PyTorch 2.0:
# Create and activate the virtual environment
python3 -m venv .pt2
source .pt2/bin/activate
# Install required packages from PyPI
pip3 install -r requirements/pt2.txt
3. Installing sgm
The next step involves the installation of sgm. While in your virtual environment, run the following command:
pip3 install .
This command installs the sgm package which is essential for the functioning of the generative models.
4. Installing sdata for Training
