sudo xcodebuild -license accept

• You should now be ready to start converting models!

Step 1: Download and install Guernika Model Converter.

Step 2: Launch Guernika Model Converter from your Applications folder, this app may take a few seconds to load.

Step 3: Once the app has loaded you will be able to select what model you want to convert:

• You can input the model identifier (e.g. CompVis/stable-diffusion-v1-4) to download from Hugging Face. You may have to log in to or register for your Hugging Face account, generate a User Access Token and use this token to set up Hugging Face API access by running huggingface-cli login in a Terminal window.

• You can select a local model from your machine: Select local model

• You can select a local .CKPT model from your machine: Select CKPT

Step 4: Once you've chosen the model you want to convert you can choose what modules to convert and/or if you want to chunk the UNet module (recommended for iOS/iPadOS devices).

Step 5: Once you're happy with your selection click Convert to Guernika and wait for the app to complete conversion. WARNING: This command may download several GB worth of PyTorch checkpoints from Hugging Face and may take a long time to complete (15-20 minutes on an M1 machine).
