面向開發(fā)者的LLM入門課程-評(píng)估英文版提（3）：

英文版提示

3.通過LLM進(jìn)行評(píng)估實(shí)例

langchain.debug = False

#為所有不同的示例創(chuàng)建預(yù)測(cè)
predictions = qa.apply(examples)

# 對(duì)預(yù)測(cè)的結(jié)果進(jìn)行評(píng)估，導(dǎo)入QA問題回答，評(píng)估鏈，通過語(yǔ)言模型創(chuàng)建此鏈
from langchain.evaluation.qa import QAEvalChain #導(dǎo)入QA問題回答，評(píng)估鏈

#通過調(diào)用chatGPT進(jìn)行評(píng)估
llm = ChatOpenAI(temperature=0)
eval_chain = QAEvalChain.from_llm(llm)

#在此鏈上調(diào)用evaluate，進(jìn)行評(píng)估
graded_outputs = eval_chain.evaluate(examples, predictions)

#我們將傳入示例和預(yù)測(cè)，得到一堆分級(jí)輸出，循環(huán)遍歷它們打印答案
for i, eg in enumerate(examples):
print(f”Example {i}:”)
print(“Question: ” + predictions[i][‘query’])

print(“Predicted Answer: ” + predictions[i][‘result’])
print(“Predicted Grade: ” + graded_outputs[i][‘results’])
