How to Use These Datasets

Here’s a suggested pattern for how to load and use these datasets in your code:

from datasets import load_dataset

ds = load_dataset("groupfairnessllm", "age_bias_with_human_label")
# ds will have splits such as train, validation, etc. (or a single default split)

# Example: examine fields
print(ds["train"].column_names)
print(ds["train"][0])

AWS bedrock Setup

export AWS_ACCESS_KEY_ID=<your_aws_access_key_id>
export AWS_SECRET_ACCESS_KEY=<your_aws_secret_access_key>
export AWS_REGION_NAME=<your_aws_region_name>

OpenAI Setup

export OPENAI_API_KEY=""

vllm Setup

Please use vllm to setup the API server for open source LLMs. For example, use the following command to deploy a Llama 3 8B hosted on HuggingFace:

python -m vllm.entrypoints.openai.api_server \
  --model meta-llama/Meta-Llama-3-8B-Instruct \
  --tensor-parallel-size 8 \
  --dtype auto \
  --api-key sk-123456789 \
  --gpu-memory-utilization 0.9 \
  --port 5000

Setup the api key:

export OPENAI_API_KEY=sk-123456789

Usage

python checking.py --model <model_name> --task <task_type> --operations <operations>

Parameters

• --model: Model name (default: Mistral)

• --operations: Operations to run - extract, check, eval_fairpair, eval_utest, eval_ttest (default: extract check eval_ttest)
• --base-path: Base directory for data (default: dataset)
• --llm-model: LLM model for processing (default: bedrock/anthropic.claude-3-5-haiku-20241022-v1:0)
• --batch-size: Batch size (default: 1)
• --llm-type: You can choose bedrock, openai or vllm
