openai_examples_projects's Issues

Problems while launching the start_training_reflex.launch

Hi Deastan,

I recently started working on Reinforcement Learning for Robotics.
I followed the steps in your Readme.md. No issues with compilation (using catkin_make).

The roslaunch is showing up the following error:

process[iiwa/start_qlearning_reflex-2]: started with pid [9121]
('Python version: ', '2.7.17 (default, Jul  1 2022, 15:56:32) \n[GCC 7.5.0]')
Traceback (most recent call last):
  File "/home/himanshu/rl_openai/src/openai_examples_projects/my_reflex_test_openai/scripts/start_qlearning_reflex.py", line 352, in <module>
    main()
  File "/home/himanshu/rl_openai/src/openai_examples_projects/my_reflex_test_openai/scripts/start_qlearning_reflex.py", line 317, in main
    env = init_env()
  File "/home/himanshu/rl_openai/src/openai_examples_projects/my_reflex_test_openai/scripts/start_qlearning_reflex.py", line 152, in init_env
    env = gym.make('iiwaMoveEnv-v0')
  File "/home/himanshu/.local/lib/python2.7/site-packages/gym/envs/registration.py", line 142, in make
    return registry.make(id, **kwargs)
  File "/home/himanshu/.local/lib/python2.7/site-packages/gym/envs/registration.py", line 87, in make
    env = spec.make(**kwargs)
  File "/home/himanshu/.local/lib/python2.7/site-packages/gym/envs/registration.py", line 58, in make
    cls = load(self.entry_point)
  File "/home/himanshu/.local/lib/python2.7/site-packages/gym/envs/registration.py", line 17, in load
    mod = importlib.import_module(mod_name)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named iiwa_tasks.iiwa_move

Any idea how to figure this out?

Having error while start simulation

I am running shadow_tc_learn_to_pick_ball_qlearn-2
Screenshot from 2021-08-20 00-38-49
example to pick and drop the ball using robot arm. I started the launch file and it loads all the nodes and controller perfectly but then it stuck on env.reset() function and print the below error
[ERROR] [1629400456.686879]: NO RESET SIMULATION SELECTED
I have tried many things but nothing works.
Please help anyone.

Thank you
