langchain version compatible

[qingyuan18]

when running the aistyle.ipynb， the langchain import throws execption ：

---

ImportError Traceback (most recent call last)
Cell In[12], line 4
2 from langchain.embeddings import BedrockEmbeddings
3 from langchain.vectorstores import FAISS
----> 4 from langchain.indexes.vectorstore import VectorStoreIndexWrapper
---> 21 from sqlalchemy import (
22 URL,
....etc
41 from sqlalchemy.ext.declarative import declarative_base

ImportError: cannot import name 'URL' from 'sqlalchemy' (/home/ec2-user/anaconda3/envs/pytorch_p310/lib/python3.10/site-packages/sqlalchemy/init.py)

it seems like the langchain version is incompatible with my own env

do we have a requirements.txt for the dependence lib with versions for this lab?

thanks

problem solved by upgrade the sqlalchemy lib, but another incompatible issue throws out:
TypeError Traceback (most recent call last)
Cell In[9], line 37
31 vectorstore_faiss = FAISS.from_documents(
32 documents,
33 bedrock_embeddings,
34 )
36 wrapper_store_faiss = VectorStoreIndexWrapper(vectorstore=vectorstore_faiss)
---> 37 query_embedding = vectorstore_faiss.embedding_function(customer_input)
38 np.array(query_embedding)

TypeError: 'BedrockEmbeddings' object is not callable

really needs requirements.txt for specific dependence lib versions ...

thanks again
