这是完整的代码。在https://learn.deeplearning.ai/的笔记本上运行得很好。但当我在本地机器上运行时，出现了关于

ImportError: Could not import docarray python package

的错误。我尝试重新安装/强制安装了langchain和lanchain[docarray]（使用pip和pip3）。我使用的是mini conda虚拟环境，Python版本为3.11.4

from langchain.vectorstores import DocArrayInMemorySearchfrom langchain.schema import Documentfrom langchain.indexes import VectorstoreIndexCreatorimport openaiimport osos.environ['OPENAI_API_KEY'] =  "xxxxxx" #在DLAI中不需要docs = [    Document(        page_content="""[{"API_Name":"get_invoice_transactions","API_Description":"这个API调用时会提供交易列表","API_Inputs":[],"API_Outputs":[]}]"""    ),    Document(        page_content="""[{"API_Name":"get_invoice_summary_year","API_Description":"这个API按供应商、产品和年份汇总发票","API_Inputs":[{"API_Input":"Year","API_Input_Type":"Text"}],"API_Outputs":[{"API_Output":"Purchase Volume","API_Output_Type":"Float"},{"API_Output":"Vendor Name","API_Output_Type":"Text"},{"API_Output":"Year","API_Output_Type":"Text"},{"API_Output":"Item","API_Output_Type":"Text"}]}]"""    ),    Document(        page_content="""[{"API_Name":"loan_payment","API_Description":"这个API计算贷款的月供","API_Inputs":[{"API_Input":"Loan_Amount","API_Input_Type":"Float"},{"API_Input":"Interest_Rate","API_Input_Type":"Float"},{"API_Input":"Loan_Term","API_Input_Type":"Integer"}],"API_Outputs":[{"API_Output":"Monthly_Payment","API_Output_Type":"Float"},{"API_Output":"Total_Interest","API_Output_Type":"Float"}]}]"""    ),    Document(        page_content="""[{"API_Name":"image_processing","API_Description":"这个API处理图像并应用指定的滤镜","API_Inputs":[{"API_Input":"Image_URL","API_Input_Type":"URL"},{"API_Input":"Filters","API_Input_Type":"List"}],"API_Outputs":[{"API_Output":"Processed_Image_URL","API_Output_Type":"URL"}]}]"""    ),    Document(        page_content="""[{"API_Name":"movies_catalog","API_Description":"这个API根据用户偏好提供电影目录","API_Inputs":[{"API_Input":"Genre","API_Input_Type":"Text"},{"API_Input":"Release_Year","API_Input_Type":"Integer"}],"API_Outputs":[{"API_Output":"Movie_Title","API_Output_Type":"Text"},{"API_Output":"Genre","API_Output_Type":"Text"},{"API_Output":"Release_Year","API_Output_Type":"Integer"},{"API_Output":"Rating","API_Output_Type":"Float"}]}]"""    ),    # 在这里添加更多文档   ]index = VectorstoreIndexCreator(        vectorstore_cls=DocArrayInMemorySearch        ).from_documents(docs)api_desc = "对电影进行分析"query = f"根据以下API描述搜索相关API：{api_desc}\        以JSON对象的形式返回API的page_contents列表。"print(index.query(query)) 

这是错误信息：

Please install it with `pip install "langchain[docarray]"`.

回答：

尝试这样安装：pip install docarray
