Usage
You will need to start the container each time you want to use the node.
To do this, navigate to the NVIDIA-Workbench profile in Terminal (see getting started section) and run the following command:
podman run -it --rm \
--device=nvidia.com/gpu=all \
--shm-size=16GB \
-e NGC_API_KEY=$NGC_API_KEY \
-v "$LOCAL_NIM_CACHE:/opt/nim/.cache" \
-u $(id -u) \
-p 8000:8000 \

The first time you run this it will download and configure the container, this may take a while.
After the container is running you can then simply add the NIM SDXL node to generate images, download the example workflow here or you can drag the image below into ComfyUI to view the embedded workflow:
