Headless No GUI Commands?

[desifisker]

I am running instant-ngp on a remote server and x11 port forwarding isnt working so I want to run it headless.

The read me has the command to start running the fox example without a gui, do I just add the tag --no-gui to all commands to proceed with training and using custom data with colmap? What about the commands for saving a .ingp file and loading a .ingp file?
