Fail to run 'HandManipulateBlock-v0'

Thanks for the nice api. I managed to run CartPole-v0 using python example_agent.py command. Now I need to run HandManipulateBlock-v0. But this environment is not available in gym 0.7.4 (specified in requirements.txt). So I changed the versions of numpy, gym and requests in requirements.txt to the following: numpy==1.15.0, gym==0.10.5, requests==2.19.1 Now gym-http-api recognizes HandManipulateBlock-v0 environment. But when I try to run the environment using python example_agent.py, the execution halts with the followint exception:

Traceback (most recent call last): File “/home/navid/gym-http-api/gym_http_client.py”, line 22, in _parse_server_error_or_raise_for_status j = resp.json() File “/home/navid/my-gym-http-api/lib/python3.5/site-packages/requests/models.py”, line 896, in json return complexjson.loads(self.text, **kwargs) File “/usr/lib/python3.5/json/init.py”, line 319, in loads return _default_decoder.decode(s) File “/usr/lib/python3.5/json/decoder.py”, line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File “/usr/lib/python3.5/json/decoder.py”, line 357, in raw_decode raise JSONDecodeError(“Expecting value”, s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Could anyone give me some hint about how to fix this? Thanks. Best regards, Navid

It would be useful to have, but maybe not in the primary gym repo. External bindings could be a separate package instead.

Okay, not a problem, but I would suggest adding a note to the README:

This repo is not actively supported beyond commit ___. Proceed at your own risk if using package version greater than those defined in requirements.txt, as some gym/mujoco functions and environments may not be useable.

And yes I’m familiar with the C extension API, having used it with Boost.Python and pybind. If I end up implementing the bindings, would this be desired functionality for the gym repo?
