You should install d4rl, and import d4rl before gym.make()

After I import d4rl first, this error remians. Can anyone help me with it?

maybe you didn't install mlrl

I had the same problem, but after installing D4RL using this method from the D4RL README, I was able to download the data sets such as halhcheetah-midium-v2 and others. https://github.com/Farama-Foundation/D4RL#setup Perhaps you should also make sure that MuJoCo2.1.0 is downloaded correctly.

Hope this helps.
