We renamed the "mixed" environments to "medium-replay" as a more descriptive name (they are training replay buffers taken from the medium agent).

ant-random-expert-v0 is not throwing an error for me - could you post what error you are getting?

from d4rl.

Thank you Justin! Following your suggestion, I can import "medium-replay" env correctly.

>>> env = gym.make("ant-medium-replay-v0")
/home/mirror/anaconda3/lib/python3.7/site-packages/gym/logger.py:30: UserWarning: WARN: Box bound precision lowered by casting to float32
  warnings.warn(colorize('%s: %s'%('WARN', msg % args), 'yellow'))

However, there is still a problem when importing 'ant-random-expert-v0' environment.
Here is the error raised by making 'ant-random-expert-v0' environment.

Could you make sure you are running an up-to-date version, and that 'ant-random-expert-v0' is registered at this line? https://github.com/rail-berkeley/d4rl/blob/master/d4rl/gym_mujoco/__init__.py#L237
