我们首先来探讨一下这种存储器的基本功能。
示例代码因此缓冲区不会变得太大。
我们首先来探讨一下这种存储器的基本功能。
示例代码
from langchain.memory import ConversationBufferWindowMemorymemory ConversationBufferWindowMemory( k1)
memory.save_context({input: hi}, {output: whats up})
memory.save_context({input: not much you}, {output: not much})memory.load_memory_variables({})输出结果 {history: Human: not much you\nAI: not much}我们还可以获取历史记录作为消息列表如果您将其与聊天模型一起使用这非常有用。
示例代码
memory ConversationBufferWindowMemory( k1, return_messagesTrue)
memory.save_context({input: hi}, {output: whats up})
memory.save_context({input: not much you}, {output: not much})memory.load_memory_variables({})输出结果 {history: [HumanMessage(contentnot much you, additional_kwargs{}),AIMessage(contentnot much, additional_kwargs{})]}Using in a chain
让我们看一下示例再次设置 verboseTrue 以便我们可以看到提示。
