openai-gym is an OCaml binding for openai-gym open-source library. It is built as a client for the gym-http-api REST API.
To use the openai-gym package, you need to have a gym-http-api server runnung:
python3 gym_http_server.py
The documentation of the openai-gym package is available online or in the directory docs.
You can install openai-gym with the following command:
opam install openai-gym
Opam can also be used to compile and install from the source directory. For that you first need to pin the source directory. So, from this directory, do:
opam pin add openai-gym .
Then you can install using the command:
opam install openai-gym
If the source files are modified, the packages must be reinstalled with the command:
opam reinstall openai-gym
To build from source, you will need to install the dependencies
listed in the depends field of the *.opam files.
An easy way to get set up on most platforms is to use the OCaml package manager (https://opam.ocaml.org). Once opam is installed, you can just add the corresponding libraries:
opam install ocamlfind dune atdgen atd cohttp-lwt-unix ...
To compile, do:
make
To test, do:
make test
To generate the documentation, do:
make doc
