I worked on docker container. I got this libGL error

Hi, unless you specifically set up docker to forward the GUI to your main operating system, you won't be able to run the GUI from within docker. See the docker thread for more info: https://github.com/NVlabs/instant-ngp/issues/20

If you just want to train models without a GUI, you can compile without linking to GL by using

cmake -DNGP_BUILD_WITH_GUI=OFF . -B build

That will side-step the failure to set up a window above.

Thanks a lot
