        ## Quick Start
        ### Installation
        
        Make sure you have Python 3.7+ installed. It is also a good idea to use a virtual environment.

        <summary>Show instructions for creating a Virtual Environment</summary>
        
        <div>
        
        ```bash
        python3 -m venv instruct-qa-venv
        source instruct-qa-venv/bin/activate
        ```
            
        </div>
        
        </details>
        
        
        You can install the library via `pip`:
        
        ```bash
        # Install the latest release
        pip3 install instruct-qa
        
        # Install the latest version from GitHub
        pip3 install git+https://github.com/McGill-NLP/instruct-qa
        ```
        
        For development, you can install it in editable mode with:
        ```
        git clone https://github.com/McGill-NLP/instruct-qa
        cd instruct-qa/
        pip3 install -e .
        ```
        
        ### Usage
        Here is a simple example to get started. Using this library, use can easily leverage retrieval-augmented instruction-following models for question-answering in ~25 lines of code. The source file for this example is [examples/get_started.py](examples/get_started.py).
        
        ```python
        from instruct_qa.collections.utils import load_collection
        from instruct_qa.retrieval.utils import load_retriever, load_index
        from instruct_qa.prompt.utils import load_template
        from instruct_qa.generation.utils import load_model
        from instruct_qa.response_runner import ResponseRunner
        
        collection = load_collection("dpr_wiki_collection")
        index = load_index("dpr-nq-multi-hnsw")
        retriever = load_retriever("facebook-dpr-question_encoder-multiset-base", index)
        model = load_model("flan-t5-xxl")
        prompt_template = load_template("qa")
        
        queries = ["what is haleys comet"]
        
        runner = ResponseRunner(
            model=model,
            retriever=retriever,
            document_collection=collection,
            prompt_template=prompt_template,
            queries=queries,
        )
        
        responses = runner()
        print(responses[0]["response"])
        # Halley's Comet Halley's Comet or Comet Halley, officially designated 1P/Halley, is a short-period comet visible from Earth every 75–76 years. Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime. Halley last appeared...
        ```
        You can also check the input prompt given to the instruction-sollowing model that contains the instruction and the retrieved passages.
        ```python
        print(responses[0]["prompt"])
        """
        Please answer the following question given the following passages:
        - Title: Bill Haley

        ...
        
        Question: what is haleys comet
        Answer:
        """
        
        ```
        Detailed documentation of different modules of the library can be found [here](instruct_qa/README.md)
        
        ## Generating responses for entire datasets
        Our library supports both question answering (QA) and conversational question answering (ConvQA) datasets. The following datasets are currently incorporated in the library
        - [Natural Questions (Open-domain)](https://huggingface.co/datasets/nq_open)
        - [HotpotQA](https://huggingface.co/datasets/hotpot_qa)
        - [TopiOCQA](https://huggingface.co/datasets/McGill-NLP/TopiOCQA)
        
        <!-- It is easy to add any HuggingFace dataset to the library by providing a mapping, as demonstrated [here](). -->
        
        Here is an example to generate responses for Natural Questions using DPR retriever and Flan-T5 generator.
        ```bash
        python experiments/question_answering.py \
        --prompt_type qa \
        --dataset_name natural_questions \
        --document_collection_name dpr_wiki_collection \
        --index_name dpr-nq-multi-hnsw \
        --retriever_name facebook-dpr-question_encoder-multiset-base \
        --batch_size 1 \
        --model_name flan-t5-xxl \
        --k 8 \
        --max_new_tokens 500 \
        --post_process_response
        ```
        
        By default, a `results` directory is created within the repository that stores the model responses. The default directory location can be overidden by providing an additional command line argument `--persistent_dir <OUTPUT_DIR>` More examples are present in the [examples](examples) directory.
        
        ## Download model responses and human evaluation data
        We release the model responses generated using the above commands for all three datasets. The scores reported in the paper are based on these responses. The responses can be downloaded with the following command:
        ```bash
        python download_data.py --resource results
        ```
        The responses are automatically unzipped and stored as JSON lines in the following directory structure:
        ```
        results
        ├── {dataset_name}
        │   ├── response
        │   │   ├── {dataset}_{split}_c-{collection}_m-{model}_r-{retriever}_prompt-{prompt}_p-{top_p}_t-{temperature}_s-{seed}.jsonl
        ```
        
        Currently, the following models are included:
        - `fid` (Fusion-in-Decoder, separately fine-tuned on each dataset)
        - `gpt-3.5-turbo` (GPT-3.5)
        - `alpaca-7b` (Alpaca)
        - `llama-2-7b-chat` (Llama-2)
        - `flan-t5-xxl` (Flan-T5)
        
        We also release the human annotations for correctness and faithfulness on a subset of responses for all datasets. The annotations can be downloaded with the following command:
        ```bash
        python download_data.py --resource human_eval_annotations
        ```
        
        The responses will be automatically unzipped in the following directory structure:
        ```
        human_eval_annotations
        ├── correctness
        │   ├── {dataset_name}
        │   │   ├── {model}_human_eval_results.json
        |
        ├── faithfulness
        │   ├── {dataset_name}
        │   │   ├── {model}_human_eval_results.json
        ```

        ## LLM-based evaluation
        The following prompt templates and instructions were used for LLM-based evaluation.
        
        ### Correctness
        ```
        System prompt: You are CompareGPT, a machine to verify the correctness of predictions. Answer with only yes/no.
        
        You are given a question, the corresponding ground-truth answer and a prediction from a model. Compare the "Ground-truth answer" and the "Prediction" to determine whether the prediction correctly answers the question. All information in the ground-truth answer must be present in the prediction, including numbers and dates. You must answer "no" if there are any specific details in the ground-truth answer that are not mentioned in the prediction. There should be no contradicting statements in the prediction. The prediction may contain extra information. If the prediction states something as a possibility, treat it as a definitive answer.
        
        Question: {Question}
        Ground-truth answer: {Reference answer}
        Prediction:  {{Model response}
        
        CompareGPT response:
        ```
        
        ### Faithfulness
        ```
        System prompt: You are CompareGPT, a machine to verify the groundedness of predictions. Answer with only yes/no.
        
        You are given a question, the corresponding evidence and a prediction from a model. Compare the "Prediction" and the "Evidence" to determine whether all the information of the prediction in present in the evidence or can be inferred from the evidence. You must answer "no" if there are any specific details in the prediction that are not mentioned in the evidence or cannot be inferred from the evidence.
        
        Question: {Question}
        Prediction:  {Model response}
        Evidence: {Reference passage}
