EGL Not Initialized Error during Resource Freeing in Robosuite #166

Closed rshkong closed 2 months ago

rshkong commented 2 months ago

This error occurs when I try to run $ python examples/train_bc_rnn.py --debug to make sure robomimic is installed correctly. I'm working on ubuntu 20.04 with a nvidia gpu

This is an expected issue that is coming from mujoco - it's harmless and can be ignored.
