World of bits

Contains environments written in Javascript that run in the browser. The environments are defined over a 210x160 grid, similar to ATARI. The top 50 pixels are devoted to the query, making the "game area" of size 160x160 pixels.

The original readme can be found in /world-of-bits/README_original.md for setup instructions.

It is used to create a docker image which runs a chrome instance with an HTML page defining the environment for the agent.

Create own Mini-wob environment

Instructions for /world-of-bits/ folder.

Create environment and register it:

• Add HTML file in world-of-bits/static/miniwob which includes method:

   window.onload = function() {
      genProblem(); // start things off on load immediately
      core.startEpisode(); // start episode with call to core library
    }
  

• Add it to world-of-bits/config.py in the global registry
• Add it to universe/universe/_init_.py to be registered in the universe docker environment (See my cloned Universe repo README for instructions to add remote runtime and environment in client)
• Add it in world-of-bits/static/core/miniwob.js to be registered as gym environment
• Further information can be found in original world-of-bits/static/README.md

Build the docker image:

• Make sure to make install before for downloading the custom docker-buildtool (required) from openAI
• The docker image to build from is changed directly to the world-of-bits image, since the link to the original base is broken - the dockerfile could be drastly reduced, but it just updates for newer versions of e.g. selenium webdriver
• make build to build the image
• make dev ENV=wob.mini.AnExperiment-v0 to run a specific environment. It can be connected to via VNC on localhost:5900
• make push to push a small change in files
• make shell to enter the image in the command shell and modify files
• For further information investigate the makefile
