错误：“builtin_function_or_method”对象没有属性“__func__”

Question

第一次使用LangChain，我按照指南操作，却收到此错误，有人知道可能出了什么问题吗？我正在使用松果和这个，我不确定这是否有区别。

对于我的 Pinecone API 环境，我使用“us-east-1” - 我不确定这是否是正确的格式？

如果有任何意见，我将不胜感激！

提前非常感谢:)

这是我的代码：

from langchain_community.vectorstores import DocArrayInMemorySearch

vectorstore1 = DocArrayInMemorySearch.from_texts(
    [
        "Mary's sister is Susana",
        "John and Tommy are brothers",
        "Patricia likes white cars",
        "Pedro's mother is a teacher",
        "Lucia drives an Audi",
        "Mary has two siblings",
    ],
    embedding=embeddings,
)

我收到此错误：

AttributeError                            Traceback (most recent call last)

     12     embedding=embeddings,

不确定要尝试什么！

我猜你正在使用Python 3.12，降级到Python 3.11，它应该可以正常工作
