I just tried running your script on my Macbook, and it seems to work just fine. Can you give further details of what machine you're running on and how I might reproduce the error?

thanks. I run this script in ubuntu16.04. when I remove the env.render() I will work fine.
if I add it after env.step(action), and save the image from obs["image"] can be randomly dark.
Now, when I found a way to avoid it just remove env.render(), so it may be not necessary rush to deal with it~
Ah I see - we've also seen similar problems on Ubuntu when trying to render on screen and off screen simultaneously. This could be a problem with mujoco-py
, we're not positive.
may be a problem with mujoco-py and existed in ubuntu~ just remove env.render() may work well~
Hi, When I try to save some images I found there are some black in the normal images. I want to know how can I avoid it and if I don't render the env, will it exist? the dark images:
