根据您使用的向量存储,此步骤可能会有所不同。
# 安装faiss-cpu库
%pip install faiss-cpu > /dev/null
# 安装google-search-results库
%pip install google-search-results > /dev/null
# 导入InMemoryDocstore类
from langchain.docstore import InMemoryDocstore
# 从langchain_community.vectorstores模块中导入FAISS类
from langchain_community.vectorstores import FAISS
Note: you may need to restart the kernel to use updated packages. Note: you may need to restart the kernel to use updated packages.
# 定义嵌入模型
embeddings_model = OpenAIEmbeddings()
# 初始化空的向量存储
import faiss
embedding_size = 1536
index = faiss.IndexFlatL2(embedding_size)
vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})
BabyAGI依赖于三个LLM链条:
注意:在这个笔记本中,执行链条现在将是一个代理。
# 导入所需的模块
from langchain.agents import AgentExecutor, Tool, ZeroShotAgent
from langchain.chains import LLMChain
from langchain_community.utilities import SerpAPIWrapper

# 创建 LLMChain 实例,将 OpenAI 模型和提示作为参数传入
llm_chain = LLMChain(llm=llm, prompt=prompt)
# 获取工具名称列表
tool_names = [tool.name for tool in tools]
# 创建 ZeroShotAgent 实例,将 LLMChain 实例和允许使用的工具名称列表作为参数传入

# 使用 AgentExecutor 类从 Agent 和工具列表创建 AgentExecutor 实例
# 设置 verbose 参数为 True,以便在执行过程中打印详细信息

# 调用baby_agi函数,并传入一个字典作为参数
