This repository contains a reference implementation DRRN as mentioned in Interactive Fiction Games: A Colossal Adventure, that has been modified for use with the ScienceWorld environment.
Install Dependencies:
# Clone repository
git clone https://github.com/cognitiveailab/drrn-scienceworld.git
cd drrn-scienceworld
# Create conda environment
conda create --name drrn1 python=3.8
conda activate drrn1
pip install -r requirements.txt
An example of training the DRRN model (using 8 threads, for 10k training steps, evaluating on dev every 1k steps):
cd drrn
python3 train-scienceworld.py --num_envs=8 --max_steps=10000 --task_idx=13 --simplification_str=easy --priority_fraction=0.50 --memory_size=100000 --env_step_limit=100 --eval_freq=1000 --eval_set=dev --historySavePrefix=drrn-task13-results-seed0-dev Here:
This configuration generally takes about 1-2 hours to run (to 10k steps).

The GPU memory requirements are variable, but generally stay below 8gb.
Many threads: If you are attempting to use a large number of threads (e.g. 20+), you may need to add an additional several-second delay after the threads spawn before the rest of the program runs. (The ScienceWorld API already adds a 5 second delay, which handles small numbers of threads well.)
Model saving with manys steps: Very occassionally, on very long runs (generally 1M+ steps), the periodic pickling the model when saving checkpoints runs into issues and freezes. The cause is unknown, but as a workaround the save has been wrapped in a timeout, so that if it takes longer than 2 minutes to save the model, the checkpoint is not saved and training continues. Subsequent checkpoints usually save without issue.
