Cannot connect to X server #12

I was trying to run herdemo_needlepick.sh to test the environment after installing, the error suggested that the file ../surrol/data/demo/data_NeedlePick-v0_random_100.npz does not exist. Therefore, I ran python data_generation.py --env NeedlePick-v0 in surrol/data to get training data, and it showed the following error.

\ Do you know what might be the problem? Thank you in advance!

Since my cluster doesn't support visual, therefore I have changed render_mode='rgb_array', and everything works fine now.
