Change the device for rendering

[wadiuvatzy]

I am using mujoco-py to do some RL tasks.
When I am runing the program, it will output
"Found 8 GPUs for rendering. Using device 0"

When I want to get more processes, cuda: 0 is out of memory. So I want to change the default device for rendering but I donot know how.

I have tried to add "CUDA_VISIBLE_DEVICES=1" before the python command. But there is another error coming out.

I have no idea how to fix this.

So could you tell me how to change the device for rendering?
