env.render() returns None

[jayaramreddy10]

Hi,

I am trying to render image during rollout of my SAC policy on door-lock task using command: frame = env.render(mode='rgb_array')

And frame turns out to be None rather than image.

How do I get the rendered image? Do I need to add any other additional arguments in this command: frame = env.render(mode='rgb_array') ?

Hi sorry, our documentation needs to be updated. Follow the examples here: https://metaworld.farama.org/rendering/rendering/ You just need to set a render mode upon creation of the environment and then call frame = env.render()

Render mode should be set during environment initialization. Check the documentation for examples
