ImportError: cannot import name 'register_goal_example_envs'

Hi, avisingh599 .

I have built docker image from README. But when I run "softlearning run_example_local examples.classifier_rl --n_goal_examples 10 --task=Image48SawyerDoorPullHookEnv-v0 --algorithm VICERAQ --num-samples 5 --n_epochs 300 --active_query_frequency 10" . There is a problem:

Traceback (most recent call last):

    from multiworld.envs.mujoco import register_goal_example_envs
ImportError: cannot import name 'register_goal_example_envs'

The pip show that i have installed multiworld and I can import it in python cli:

>>> import multiworld.envs.mujoco as mu
>>> mu
<module 'multiworld.envs.mujoco' from '/opt/conda/envs/softlearning/lib/python3.6/site-packages/multiworld/envs/mujoco/__init__.py'>
>>> dir(mu)
['LOGGER', '_REGISTERED', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'create_image_48_sawyer_push_and_reach_arena_env_reset_free_v0', 'create_image_48_sawyer_push_and_reach_arena_env_v0', 'create_image_48_sawyer_reach_xy_env_v1', 'create_image_84_sawyer_reach_xy_env_v1', 'gym', 'logging', 'register', 'register_custom_envs']

It seem like the multiworld.envs.mujoco mudule do not has register_goal_example_envs.

How can I solove this problem? Thanks!
