So I am doing the tutorial from Openai_ros http://wiki.ros.org/openai_ros/Turtle...,

And when I tried launching my file: roslaunch my_turtlebot2_training start_training.launch , I got the following error:

  File "/home/afrl/catkin_ws/src/my_turtlebot2_training/src/my_start_qlearning_wall_v2.py", line 11, in <module>
    from openai_ros.openai_ros_common import StartOpenAI_ROS_Environment

I think it might be I did not check out the version2 of openai_ros. Any help will be appreciated.

I would definitely check out version2 since it is mentioned in the tutorials and there seem to be some recent bug fixes on that branch. I recently went through the tutorial and it worked well. If this didn't solve your problem, I would recommend to ensure that you are using the correct python version.
