Quickstart

Before running: You will have to have Java 1.8+ installed on your system (shipped with most linux distributions) and Python 3.8+. We recommend creating a conda environment like this:

conda create --name scienceworld python=3.8
conda activate scienceworld

Then, install ScienceWorld either from PyPi:

pip install scienceworld

or from source in development mode:

git clone https://github.com/allenai/ScienceWorld.git
cd ScienceWorld
pip install .

Run an example random agent, on task 13 (classification: place a non-living thing in a box), for 5 episodes:

python examples/random_agent.py --task-num=13 --num-episodes=5 --simplifications-preset easy

Run a user console where you can interact with the environment, on task 3 (change of state: melting):

python examples/human.py --task-num=3 --num-episodes=5

Web Server Demo

A web server demo is also available, that allows running a ScienceWorld user console that can be interacted with in a web browser.

To run the web server demo:

conda create --name scienceworld python=3.8
conda activate scienceworld
pip install scienceworld[webserver]

Run the web server:

python examples/scienceworld-web-server-example.py

Point your web browser to: localhost:8080

ScienceWorld Design

ScienceWorld is written in Scala (2.12.9), and compiles using sbt into a JAR file that is run with Java. For convenience, a Python API is provided (Python >= 3.8), which interfaces using the py4j package.

If you modified the Scala code, you can recompile the JAR file by running:

./simulator/package.sh
pip install -e .

Tasks

The tasks are listed in the table below along with their number of variations. Either the task ID or its name can be used to a task with env.load().
