    If you face a error of ModuleNotFoundError: No module named 'robot_bases' on pybullet 2.5.0,
you should modify a source code of pybullet.
This issue may be fixed on future release because the pybullet source code is updated on github.
If you are using anaconda, you need to modify /anaconda3/envs/XXXX/lib/python3.6/site-packages/pybullet_envs/robot_locomotors.py.
Please open robot_locomotors.py.
You can see...
 from robot_bases import XmlBasedRobot, MJCFBasedRobot, URDFBasedRobot
 import numpy as np
 import pybullet
 import os
 import pybullet_data
 from robot_bases import BodyPart
You need to add pybullet_envs. for robot_bases like follows.
 from pybullet_envs.robot_bases import XmlBasedRobot, MJCFBasedRobot, URDFBasedRobot
 import numpy as np
 import pybullet
 import os
 import pybullet_data
 from pybullet_envs.robot_bases import BodyPart
