Version of gym for a2c

[ahsteven]

Today I was able to get the baslines installed with gym and run some examples. From other posts, for installing mujoco-pi the following combination had to be used:

python 3.5.2
mujoco 131
mujoco_py 0.5.7
gym 0.9.3

This combination works for some things however my goal is to train a2c on atari games so when I run
(gym-py35) teves@teves:~$ python -m baselines.a2c.run_atari

I get the error:

Traceback (most recent call last):
File "/home/teves/anaconda3/envs/gym-py35/lib/python3.5/runpy.py", line 184, in _run_module_as_main
"main", mod_spec)

File "/home/teves/baselines/baselines/common/cmd_util.py", line 7, in
from gym.wrappers import FlattenDictWrapper
ImportError: cannot import name 'FlattenDictWrapper'

This seems like because I am running an older gym version. Is that correct? What versions of the above shoule I have installed to use a2c?

update: I was able to upgrade to gym 0.10.3 and was able to install mujoco using pip install mujoco-py==0.5.7 however I was not able to install it using: pip install -e '.[mujoco]'.

Then I was able to run a2c example but not acktr.

(gym) teves@teves:~$ python -m baselines.acktr.run_atari

I was able to update to 10.3 and get A2C to work. However, ACKTR still is not working. After running:

python -m baselines.acktr.run_atari

I get:

If this is working for anybody else please let me know your setup.

Has anyone been able to get around this issue for acktr?

[windyyc]

I add comment in kfac.py at lines 120 to avoid this error, but I don't know it whether or not brings some problems.
the file baselines/acktr/kfac.py

upgrade your version of gym(I think 0.9.6 is latest verified at the time of writing this)

pip install git+git://github.com/openai/gym==0.9.6 --upgrade

[NishanthVAnand]

I am still facing this issue. Can anyone tell me how to fix this
