If you’re interested in offline Reinforcement Learning for Natural Language Generation, the sample project Implicit Language Q Learning (ILQL) is a great place to start. This guide will take you through the necessary steps to set up this project efficiently, troubleshoot potential issues, and understand the core concepts along the way.

Setup Instructions

Preprocessed Data and Reward Model

The project requires preprocessed data and a reward model to function. You can download these resources as follows:

• Download data.zip and outputs.zip from Google Drive.
• Place the downloaded and unzipped folders, data and outputs, at the root of the repository.
• data contains the preprocessed data for all tasks, and outputs contains the checkpoint for Reddit comments upvote reward.

Dependencies and PYTHONPATH

This repository is designed for Python 3.9.7. To set it up, run:

• shell
• pip install -r requirements.txt
• export PYTHONPATH=$PWD/src

Running Visual Dialogue Experiments

To execute the Visual Dialogue experiments, you need to serve the Visual Dialogue environment on localhost. Instructions for this can be found here.

Toxicity Filter Reward Setup

To run the Reddit comment experiments with the toxicity filter reward, follow these steps:

1. Create an account for the GPT-3 API here.
2. Export your API key: export OPENAI_API_KEY=your_API_key.

Running Experiments

To run any experiments, follow these instructions:

• Navigate to the scripts directory.
• Execute the script with python script_name.py.
• Optionally, edit the configuration file, or provide command-line arguments in hydra style, like so: python script_name.py eval.bsize=5 train.lr=1e-6 wandb.use_wandb=false.
• For data parallel training or evaluation on multiple GPUs:
  python -m torch.distributed.launch --nproc_per_node [N_GPUs] --use_env script_name.py arg1=a arg2=b.

Explaining Code Like an Analogy

Imagine you’re a chef preparing a complex dish. In our project, you have various ingredients (data) and tools (scripts and libraries) at your disposal. Each step in your recipe represents a section of the code and contributes to the final dish (successful training and evaluation of the model).

For instance, the initial setup is akin to gathering and preparing your ingredients before you start cooking. The mixing of ingredients corresponds to running scripts that bring the various components of AI together, such as data processing and training the model. Just as a chef might adjust the cooking time based on taste tests, you can tweak parameters and configurations in your scripts for optimal results.

Troubleshooting Tips

If you encounter issues while setting up or running the project, consider the following troubleshooting steps:

• Ensure you’ve downloaded all necessary files and placed them in the correct directories.
• Check that your Python environment matches the required version (3.9.7).
• Verify that your API key for GPT-3 is set correctly and is valid.
• If you encounter running errors, look into logs for supervision and adjust configurations accordingly.
