Convert LoRa

pip install torch==1.13.1 safetensors diffusers==0.14.0 transformers==4.27.1 accelerate==0.17.1

In format_convert.py update the model_id, safetensor_path variable with the path to the safetensor file you downloaded, and the bin_path variable with the desired output path for the bin file.

python format_convert.py

Push model to Huggingface

1. Create repository on Huggingface
2. Clone it

git clone https://huggingface.co/<your-username>/<your-model-name>
cd <your-model-name>

3. Move model into the directory
4. Download git-lfs

sudo apt update
sudo apt install git-lfs

5. Initialize git-lfs git lfs install
6. huggingface-cli lfs-enable-largefiles .
7. Push

# Create any files you like! Then...
git add .
git commit -m "First model version"  # You can choose any descriptive message
git push

Cog Model Edits

Once Cog is installed and the base Cog model is cloned, the following edits need to be made within the cloned directory.

1. Update cog.yaml, add the latest version of runpod to the requirements within the cog.yaml file.
2. Add a .env file with the required environment variables.
3. Add the worker file
4. chmod +x worker

Finally, test the worker locally with cog run ./worker

Building Container and Pushing it to Docker Hub

Once the worker is tested locally, the container can be built.

sudo cog build -t ai-api-{model-name}
sudo docker tag ai-api-{model-name} runpod/ai-api-{model-name}:latest

sudo docker login
sudo docker push runpod/ai-api-{model-name}:latest

Replacing ai-api-{model-name} and runpod with your own model name and dockerhub username.

Docker Quick Reference

Before a worker container can be started, Docker Engine is required to be on the host machine.
