Does anyone know how to solve this problem?

I met the same problem. Have you solved this?

I solved. The following two lines of code conflict with each other and cannot be implemented at the same time, which is a bug of mujoco_py.

viewer = mujoco_py.MjViewer(sim)
image = sim.render(width=300, height = 300, camera_name='cam0', depth=False)

Hello, Stone!
I agree that the error is caused by implementing these two lines of code together. But how should we solve it. Could you please share some suggestions?
Thank you very much.
