Error: Missing 'remote_manager' attribute in VNCEnv when executing OpenAI Universe demo

I’m facing an issue with an OpenAI Universe example. I’m using Python 3.5 on Linux Mint 18. I installed OpenAI gym and universe via pip, and while the gym examples run correctly, a Universe example fails with an error.

Here’s an alternative version of the code I’m testing:

import gym
import universe

env = gym.make('racing.FastLane-v0')
obs = env.reset()

while True:
    action = [[('KeyPress', 'Right', True)] for _ in obs]
    obs, reward, done, info = env.step(action)
    env.render()

The error indicates that the ‘VNCEnv’ object is missing the ‘remote_manager’ attribute, specifically on the env.reset() call. Has anyone encountered this before? Any suggestions would be appreciated. Thanks!

I encountered a similar issue when working with OpenAI Universe. The ‘remote_manager’ error often occurs due to version incompatibilities or missing dependencies. First, ensure you have the latest versions of gym and universe installed. If that doesn’t resolve it, try explicitly installing docker-py and go-vncdriver packages.

Another potential solution is to use a specific version of universe that’s known to work with your Python version. For Python 3.5, you might have better luck with universe==0.21.3.

If problems persist, consider using a virtual environment to isolate your project dependencies. This can help avoid conflicts with system-wide packages. Lastly, check if your firewall or antivirus is blocking any necessary connections for Universe to function properly.
