Using Hugging Face Datasets#
This example shows how to use Hugging Face datasets to evaluate models. Specifically, we show how to load examples to evaluate models on from Hugging Face’s dataset package.
Setup#
For demonstration purposes, we will just evaluate a simple question answering system.
from langchain.prompts import PromptTemplate
from langchain.chains import LLMChain
from langchain.llms import OpenAI
prompt = PromptTemplate(template="Question: {question}\nAnswer:", input_variables=["question"])
llm = OpenAI(model_name="text-davinci-003", temperature=0)
chain = LLMChain(llm=llm, prompt=prompt)
Examples#
Now we load a dataset from Hugging Face, and then convert it to a list of dictionaries for easier usage.
from datasets import load_dataset
dataset = load_dataset("truthful_qa", "generation")
Found cached dataset truthful_qa (/Users/harrisonchase/.cache/huggingface/datasets/truthful_qa/generation/1.1.0/70210b72382652635215516e59663843b88eda16bd2acef909fb46700beb039a)
examples = list(dataset['validation'])[:5]
