Describe the bug I am working with the library for keras-rl (https://github.com/keras-rl/keras-rl) when I try to run any algorithm workin on a mujoco environment the visualization fails giving me an error in the mujoco-py package:

File "ddpg_mujoco.py", line 76, in <module> agent.test(env, nb_episodes=5, visualize=True, nb_max_episode_steps=200) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/rl/core.py", line 353, in test callbacks.on_action_end(action) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/rl/callbacks.py", line 101, in on_action_end callback.on_action_end(action, logs=logs) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/rl/callbacks.py", line 366, in on_action_end self.env.render(mode='human') File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/gym/core.py", line 275, in render return self.env.render(mode, **kwargs) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/gym/core.py", line 275, in render return self.env.render(mode, **kwargs) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/gym/envs/mujoco/mujoco_env.py", line 118, in render self._get_viewer(mode).render() File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/gym/envs/mujoco/mujoco_env.py", line 130, in _get_viewer self.viewer = mujoco_py.MjViewer(self.sim) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/mujoco-py/mujoco_py/mjviewer.py", line 133, in __init__ super().__init__(sim) File "/media/DATA/anaconda3/envs/kerasrl/lib/python3.6/site-packages/mujoco-py/mujoco_py/mjviewer.py", line 26, in __init__ super().__init__(sim) File "mjrendercontext.pyx", line 278, in mujoco_py.cymj.MjRenderContextWindow.__init__ File "mjrendercontext.pyx", line 66, in mujoco_py.cymj.MjRenderContext.__init__ File "mjrendercontext.pyx", line 87, in mujoco_py.cymj.MjRenderContext._set_mujoco_buffers RuntimeError: Window rendering not supported

It is not clear to me the meaning of the error. Any help would be appreciated

I'm not sure what causes this, but a work-around that works for me is to use env.sim.render(width=w, height=h, camera_name=...)

Hi，@giorgionicola， I have same issue like your, have you fixed it?
