# OpenAI gym Docker Image

This Docker image comes with openai and pytorch-cpu. This allows users to start working on reinforcement learning in a couple of easy steps.

This image is particularly ideal for Windows users, for whom openai gym is not easily installed.

Current features:

* cpu enabled pytorch

* classic control gym environments

* box2d environments

* Recording of environments

To be developed:

* Automated environment recording (no manual command entry)

* environment rendering

* Atari environments

* cpu enabled tensorflow

## How to use

1. Either

    - Clone the repo and build the image: `docker build --tag=image_name .`

    - pull the image: `docker pull ttitcombe/rl_pytorch:latest`

2. Launch the container: `docker run -it --name=container_name image_name python`. This should enter the python interpreter.

3. Before entering the python interpreter, a script to attach the graphical display should have been run. 

4. If you want to re-enter the container and record, you can run `/usr/local/bin/startup_script.py` as the `CMD`, 

e.g. `docker exec -it container_name /usr/local/bin/startup_script.py`. This should enter a bash script.  

Alternatively, you can open a bash script and run it from there. 

5. If you want to re-enter the container, record, AND run something, try

`/usr/local/bin/startup_script.py "python /path/to/my/file.py"` as your `CMD`.

6. If you don't care about recording, use `/bin/bash` to enter bash or `python` to enter the python interpreter.

To test that the container works, try recording an environment:

```python

import gym

import torch

env_to_wrap = gym.make("LunarLander-v1")

env = gym.wrappers.Monitor(env_to_wrap, "someDir")

frame = env.reset()

is_done = False

while not is_done:

  action = env.action_space.sample()

  _, _, is_done, _ = env.step(action)

env.close()

env_to_wrap.close()

``` 

If this doesn't throw an error, then congratulations, you can record OpenAI gym!

You can extract the recording once you are outside of the container with the command `docker cp container_name:/path/to/my/file local/path/to/file`.
