[gautam1858]

could you please point out the library for rl_algs ?

[kvfrans]

Hi, I've pushed an update that should contain the relevant classes from rl-algs

[gautam1858]

unable to find tinkerbell package, please point out a resource and It would be helpful if you add requirement.txt file, thank you :)

[kvfrans]

cleaned out the references to tinkerbell, let me know if any libraries still missing

[gautam1858]

rl-algs distributions.py is missing, the file is called in policy_network.py line 4, please add that file as well

[kvfrans]

added

[gautam1858]

Hi, have similar error with rl_algos:

mlsh/mlsh_code$ python main.py --task AntBandits-v1 --num_subs 2 --macro_duration 1000 --num_rollouts 2000 --warmup_time 20 --train_time 30 --replay False AntAgent
Traceback (most recent call last):

    from rl_algs.common import set_global_seeds, tf_util as U
ModuleNotFoundError: No module named 'rl_algs'

Yeah i believe ther is something wrong here.
I solved the problem by creating a symbolic link of rl-algs into mlsh_code with the name "rl_algs".
i then did:
touch rl-algs/__init__.py

Not to mention the other problems with latest mujoco that i solved by:
pip3 install mujoco-py==0.5.7
(using python 3 here)
and using "mjpro131 linux" from https://www.roboti.us/index.html.

as a dirty workaround I also did:
sudo cp -R envs/mujoco /usr/local/lib/python3.5/dist-packages/gym/envs/

oh well and i added the following on top of main.py:

from gym.envs.registration import registry, register, make, spec
register(
     id='AntBandits-v1',
     entry_point='gym.envs.mujoco:AntBanditsEnv',
     max_episode_steps=1000,
)

I guess as alternative you could also modify the /usr/local/lib/python3.5/dist-packages/gym/envs/__init__.py file according to the __init__.py

in the root directory of this repository.
But thats as dirty as the workaround above i guess.

If somebody knows a clean way of using the project it would be nice :)

PS:
Not shure if everything is ok now but i get atleast the following output:

It is iteration 0 so i'm changing the goal to [0 5]

I was expecting some animations like a saw in a youtube video :(
EDIT:
Oh well .. figured it out, the master.py misses env.render() ,so there is no direct option for it.
You could place it in some loop to see whats happening, but its quite slow.

EDIT AGAIN:
Uhm I was wrong there is actualy a "--replay True" param to display an animation. (with much better framerate).
For some reason i did not check the rollouts.py
But be careful with that, it won't create checkpoints if you use it.

@kvfrans the project and results are great. In addition it would be nice to have this repo tested and working out of the box at least for the most used platforms, like Ubuntu 16.04 Python 3.5+ or 3.6+. And/or more detail instructions for running the demos. Following current readme doesn't lead to running code without errors.

[kvfrans]

Hey, the structure of the repo has been done so it should be easier to install everything. # #

[ViktorM]

Thanks Kevin! Now it looks much more clear for me, will try as soon as get to my PC.

For anyone still experiencing this issue, I had to install mpi4py

pip install mpi4py

Hi, How do you run the code? How long did the training take? I trained the task'Ant Obstacles Gen-v1'. It is so slow. The other tasks are also very slow. Is there any solution?
