A issuer about run main.py

There is a error like this:
AttributeError: 'MountainCarEnv' object has no attribute 'seed'
How to solve it ?Thank you!

Maybe there's an update on the Gym MountainCarEnv interface, you can adapt your code to the latest gym version or keep the same version exactly with this project, Hope this helps ~
