how to cancel the creation of the glew window?

[kaixindelele]

Can we cancel the creation of the glew window? This window will pop up every round. It really affect the experiment! In addition, when I run a experiment remotely in local, even if cancel render image, there will always be an error:

mujoco_ py.cymj.GlfwError : Failed to initialize GLFW

Hi kaixindelele,

You should be able to create an environment without any renderer. When you can call suite.make(...), can you make sure you set has_renderer=False and has_offscreen_renderer=False (note that in order to do the latter you also have to set use_camera_obs=False as well)?

Yes, I am sure, I set hasrenderer=False and hasoffscreen_renderer=False and use_camera_obs=False When I use gym fetch env, we can render a image without creating any glew window, why Robosuite must use glew ?

Sorry for the delay -- the window shouldn't be popping up if you haven't set any renderer to be True. What setup are you using?

It's very strange, different computers have different phenomena, when

GPU-1080 Intel® Xeon(R) CPU E5-2650 v2 @ 2.60GHz × 32 llvmpipe (LLVM 9.0, 256 bits) mujoco-py 2.0.2.13 it can render image without glew windows, with has_render=False, has_offscreen_renderer=True, use_camera_obs=False.

In another computer:

GPU-2080Ti Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz mujoco-py 2.0.2.8

Is it related to computer hardware or mujoco version? Because it can also render image without glew windows on another machine using mujoco-py1. X

Were you ever able to resolve this issue?

After testing, the same code, it have to create a glew window with offscreen on two different Ubuntu16.04 computers; On the another two Ubuntu 18.04 computers, offscreen does not need to create a glew window; I wonder if you also have this phenomenon?
