This article is part of the following article to address some installation issues:

After installing langchain[all], You might face the following error after you install langchain

ModuleNotFoundError: No module named 'langchain.chat_models'        

Here is what I have done:

pip install 'langchain[all]'          

It will install successfully, then the first time I try to import as follows:

from langchain.chat_models import AzureChatOpenAI

Upgrading LangChain will fix the issue. Let me know if you still face the issue.
