Building a Video Game Bot using OpenAI Universe -Error

[ZaremaSokhova]

Hello! I'm reading a book now.

I try to run the tasks that are given in the second chapter. The task where the robot learns to walk turned out to run, it works.

But when launching a program with a bot for the video game "Auto-Racing", an error occurs:

---

KeyError: 'flashgames.NeonRace-v0'

During handling of the above exception, another exception occurred:

UnregisteredEnv Traceback (most recent call last)

Could the fact that the program does not start be related to this? Installed OpenAi on a macbook with MacOS Catalina ver. 10.15.2. I will be grateful for the help.

Not the author, but the error message seems to indicate that the "flashgames.NeonRace-v0" is not installed. It is possible that there is a typo in the name. You can list all your environments with the following code snippet, that might help debugging this further.

from gym import envs
for e in envs.registry.all():
    print(e)
