Need update

[Charele]

Can someone update this project for non-Python coder?
For example, support Python3.x, support newer gym version?

python gym_http_client.py

Traceback (most recent call last):
File "gym_http_client.py", line 22, in parse_server_error_or_raise_for_status
j = resp.json()
File "C:\Miniconda3\lib\site-packages\requests\models.py", line 897, in json
return complexjson.loads(self.text, **kwargs)
File "C:\Miniconda3\lib\json_init.py", line 348, in loads
return _default_decoder.decode(s)
File "C:\Miniconda3\lib\json\decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:
