How to train on ubuntu remote system

Hi all,
I am new here to study isaac gym. I don’t own a local desktop machine, I rely on remote cluster for GPUs. I have headless docker + ssh./ conda + ssh. ,(i tried VNC, but it seems not good on isaac gym)
All the python/examples show segfault, RL env report the same error. I looked up a lot of methods but nothing worked. How can i train it just on terminal?
