Wrong URLs for downloading dataset

[frt03]

I got HTTPError: HTTP Error 404: Not Found when I tried to download some dataset.

In [56]: env = gym.make(‘halfcheetah-random-expert-v0’)                                                                                            
In [57]: dataset = env.get_dataset()                                                                                                      
Downloading dataset: http://rail.eecs.berkeley.edu/datasets/offline_rl/gym_mujoco/halfcheetah_random_expert.hdf5 to /root/d4rl_dataset/halfcheetah_random_expert.hdf5

The same error has occurred in walker2d-random-expert-v0, door-only-cloned-v0, hammer-only-cloned-v0, pen-only-cloned-v0, relocate-only-cloned-v0. I think maybe you don't make some of them available for now. If possible, could you check it?

Thanks for catching this! These were older tasks that we removed prior to release. We may add these again in the future but for now the only supported tasks are those listed on the wiki page.
