Relari Evaluation Tookit

Requirements

• Python >=3.9.0
• Poetry, official installation guide

Installation

poetry install

Usage

Before being able to use the evaluation toolkit, you need to export the API key

export RELARI_API_KEY=<your_api_key>

To run the evaluation toolkit, you then need to define the evaluation pipeline

dataset = Dataset("<path_to_dataset>")

retriever = Module(
    name="retriever",
    input=dataset.question,
    output=List[Dict[str, str]],
)

reranker = Module(
    name="reranker",
    input=retriever,
    output=List[Dict[str, str]],
)

llm = Module(
    name="llm",
    input=reranker,
    output=str,
)

pipeline = Pipeline([retriever, reranker, llm], dataset=dataset)

this will inform the evaluator about the modules and the dataset you want to use.

Suppose you have three functions retrieve, rerank, and ask that implement the threes steps of the pipeline. You can then use the ralari evaluation toolkit as follows:

from relari.eval.manager import eval_manager
from relari import RelariClient

client = RelariClient()

eval_manager.set_pipeline(pipeline)
eval_manager.set_metadata({"name": "SimpleRAG"})
with eval_manager.new_experiment as experiment:
  for sample in experiment:
    q = eval_manager.curr_sample["question"]
    # Run and log Retriever results
    retrieved_docs = retrieve(q)  # Your retrieve function
    eval_manager.log("retriever", [doc.__dict__ for doc in retrieved_docs])
    # Run and log Reranker results
    reranked_docs = rerank(q, retrieved_docs) # Your rerank function
    eval_manager.log("reranker", [doc.__dict__ for doc in reranked_docs])
    # Run and log Generator results
    response = ask(q, reranked_docs) # Your answer generation function
    eval_manager.log("llm", response)
    print(f"Q: {q}\nA: {response}\n")

eval_manager.evaluation.save(Path("results.jsonl"))
client.start_remote_evaluation()

This will run the evaluation pipeline on the dataset and log the results to the Relari API.
