Hi,

I followed the instructions for installing safety-gym and tried to make the trial example you suggested. I am getting the following error message - any ideas on what could be happening? I am running on Ubuntu 16.04 and Python 3.6.9. The printout is below; any help would be appreciated!

[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import safety_gym
>>> import gym
>>> env = gym.make('Safexp-CarGoal1-v0')

Debugged this at the poster session at NeurIPS, funnily enough.

This is the error you get if the MuJoCo license key exists, but is an empty file.

@jachiam can I get permissions on this repo so I can close issues?

aray-openai commented 4 years ago

(The fix here is to get a valid mujoco license, for MuJoCo 2.0, and make sure that mujoco-py can find it)

Hey I m having the same problem. I placed the mujoco license as instructed in ~/.mujoco/mjkey.txt but im still getting this error. How did you make sure that mujoco_py can find it?
