About OpenGL render error when processing the hdf5 dataset

[weixiang-smart]

Hello! @j96w It's an excellent work of robot learning.
When I tried to process the data downloaded from the google drive using
python scripts/dataset_states_to_obs.py --dataset 'datasets/playdata/demo_modified.hdf5' --done_mode 0 --camera_names agentview robot0_eye_in_hand --camera_height 84 --camera_width 84 --output_name image_demo_local.hdf5 --exclude-next-obs,
I got the render error about OpenGL
OpenGL.raw.EGL._errors.EGLError: EGLError( err = EGL_NOT_INITIALIZED, baseOperation = eglMakeCurrent, cArguments = ( <OpenGL._opaque.EGLDisplay_pointer object at 0x7fe287ca7dc0>, <OpenGL._opaque.EGLSurface_pointer object at 0x7fe2921ab840>, <OpenGL._opaque.EGLSurface_pointer object at 0x7fe2921ab840>, <OpenGL._opaque.EGLContext_pointer object at 0x7fe2921ab7c0>, ), result = 0 ).
Have you ever met this problem? Or I would like to know if the version of the mujoco causes this matter. My mujoco version is 3.1.1.

This is an issue from robosuite. I am not sure how to fix it myself. :(

@weixiang-smart Hi, I also encountered the same problem. Have you solved it? Thanks.

Hi @weixiang-smart @CAN-Lee , I'm still looking into this issue related to robosuite. In the meantime, feel free to download the processed dataset (image_demo.hdf5) from each dataset folder.

Same problem, solved after i switched my GPU to nvidia GPU only (because i'm using a laptop that has an intel GPU and nvidia GPU). Don't know if this works in your cases

Same error. I am actively looking for any solution.

export MUJOCO_GL=glx ,it works for me.
