dspy.History

dspy.History

基类: BaseModel

表示对话历史的类。

对话历史是一个消息列表，每个消息实体应包含来自相关签名的键。例如，如果您有以下签名

class MySignature(dspy.Signature):
    question: str = dspy.InputField()
    history: dspy.History = dspy.InputField()
    answer: str = dspy.OutputField()

那么历史应该是一个字典列表，包含“question”和“answer”等键。

示例

import dspy

dspy.settings.configure(lm=dspy.LM("openai/gpt-4o-mini"))

class MySignature(dspy.Signature):
    question: str = dspy.InputField()
    history: dspy.History = dspy.InputField()
    answer: str = dspy.OutputField()

history = dspy.History(
    messages=[
        {"question": "What is the capital of France?", "answer": "Paris"},
        {"question": "What is the capital of Germany?", "answer": "Berlin"},
    ]
)

predict = dspy.Predict(MySignature)
outputs = predict(question="What is the capital of France?", history=history)

import dspy

dspy.settings.configure(lm=dspy.LM("openai/gpt-4o-mini"))

class MySignature(dspy.Signature):
    question: str = dspy.InputField()
    history: dspy.History = dspy.InputField()
    answer: str = dspy.OutputField()

predict = dspy.Predict(MySignature)
outputs = predict(question="What is the capital of France?")
history = dspy.History(messages=[{"question": "What is the capital of France?", **outputs}])
outputs_with_history = predict(question="Are you sure?", history=history)
