proxy.client("set_state", state_str, async=True) syntax error while running code

[anirudhajitani]

When I try to clone the repo using recursive command, I get the following errors:
git clone --recursive [email protected]:sisl/MADRL.git
Cloning into 'MADRL'...
The authenticity of host 'github.com (192.30.253.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,192.30.253.112' (RSA) to the list of known hosts.
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Therefore, I cloned only this repo and cloned the rllab and rltools repo manually and added them to the PYTHONPATH as mentioned. I also installed all depenedencies from environment.yml in rllab.

However, when I run the command:
python3 runners/run_multiwalker.py rllab --control decentralized --policy_hidden 100,50,25 --n_iter 200 --n_walkers 2 --batch_size 24000 --curriculum lessons/multiwalker/env.yaml

I get the following errors:
Traceback (most recent call last):
File "runners/run_multiwalker.py", line 10, in
from madrl_environments.walker.multi_walker import MultiWalkerEnv
File "/Users/anirudhajitani/Downloads/Projects/MADRL/madrl_environments/init.py", line 1, in

proxy.client("set_state", state_str, async=True)

SyntaxError: invalid syntax

I tried to find the the function client, but the prototype for it is completely different. Can somebody tell me what I am foing wrong?

You need to git checkout the correct commit as you would get by recursive clone.

I fixed the problem of not being able to clone the repo recursively by generating and adding the ssh-key to my github account. Even then, I'm seeing the same error.

The issue is this code is not compatible with python 3.7, which has been out since June 27, 2018.
