Hi all,
I am excited about the repo but met this error after running the train.py. Any idea or thoughts on that will be appreciated.
I'm running in 3.16.0-4-amd64, and python 3.5.2
Thanks,

@fishchian - Sorry for the delay. Have you been able to run any ai gym environments before? Seems related to displaying episode videos. Are you running on a headless (e.g. no screen) server?
This link shows a very simple ai gym setup, just a few lines of code. You might verify that runs OK on your system first:
@pat-coady Hi Pat, Thank you for your response. I'm actually running in a working station and have no problem with displaying videos of Cart-Pole. However, I had problems installing the newest version of mujoco-py (1.5+) and installed 0.5.7 instead. I can also visualize my mujoco model. Look forward to more advice, thanks
Closing - will be confusing to work on this in 2 different repos. Look here:
