 Now you have two options on how to proceed. You can build the docker image from scratch or pull the existing image on the airlab docker registry. Building the image from scratch can be useful if you would like to add new dependencies or add new custom functionality. For most users just pulling the existing image will be more conveninent and fast since it doesn't require access to the Nvidia registry.
