Resolving Lingering Deprecation Warnings for ChatOpenAI and OpenAIEmbeddings in LangChain

[girithodu]

Hey, I've been tackling these deprecation warnings, following the guidance to update the import statements. Specifically, I've transitioned to using langchain_community.chat_models for ChatOpenAI and langchain_community.embeddings for OpenAIEmbedding. However, despite these adjustments, I'm still encountering the deprecation warnings outlined below:

LangChainDeprecationWarning: The class OpenAIEmbeddings was deprecated in LangChain 0.1.0 and will be removed in 0.2.0. Use langchain_openai.OpenAIEmbeddings instead.

LangChainDeprecationWarning: The class ChatOpenAIwas deprecated in LangChain 0.1.0 and will be removed in 0.2.0. Use langchain_openai.ChatOpenAI instead.

That's great to hear that you've been working on resolving the deprecation warnings by updating the import statements. It's important to stay ahead of these changes to ensure smooth transitions for future releases. Your efforts to transition to langchain_community.chat_models for ChatOpenAI and langchain_community.embeddings for OpenAIEmbedding are definitely a step in the right direction.

If you haven't already, I would encourage you to consider creating a pull request with your changes. This would allow the maintainers of LangChain to review your proposed solution and determine if it aligns with the project's goals. Keep up the good work, and thank you for your contributions to LangChain!

Try: langchain_openai.OpenAIEmbeddings rather than langchain_community.embeddings.OpenAIEmbedding

langchain_openai is a separate package

[guigevip]

langchain_openai.embeddings import OpenAIEmbeddings

[girithodu]

After successfully installing langchain_openai and managing to import OpenAIEmbeddings with langchain_openai.embeddings, I encountered an issue when attempting to import ChatOpenAI using langchain_openai.ChatOpenAI. The error message received is as follows:

 line 15, in <module>
    from langchain_openai.ChatOpenAI import ChatOpenAI
ModuleNotFoundError: No module named 'langchain_openai.ChatOpenAI'

[ttpro1995]

hi @eyurtsev , pip install langchain_openai install langchain_openai package from pip.

However, https://pypi.org/project/langchain-openai/ langchain_openai does not seem legit.
Is it fake package ?

[girithodu]

What worked for me was doing

'''from langchain_openai import ChatOpenAI,OpenAIEmbedding'''

Hi, @girithodu , I have a similar issue as yours. I kept on getting warning message:... \anaconda3\envs\py3-10-6\lib\site-packages\langchain_core_api\deprecation.py:117: LangChainDeprecationWarning: The class langchain_community.embeddings.openai.OpenAIEmbeddings was deprecated in langchain-community 0.1.0 and will be removed in 0.2.0. An updated version of the class exists in the langchain-openai package and should be used instead. To use it run pip install -U langchain-openai and import as from langchain_openai import OpenAIEmbeddings.
Here is what I did:

1. pip install -U langchain-openai
2. in code: from langchain_openai import OpenAIEmbeddings
3. I also have: from langchain_community.chat_models import ChatOpenAI; from langchain_community.llms import openai.
4. I run my app in python 3.10.6.
5. I did not get any complain/warning on my langchain_community.* models import.

It just seems from langchain_openai import OpenAIEmbeddings does not really resolve the warning message.
(By the way, from langchain_community.chat_models import ChatOpenAI never give me any error/warning message.)

Any insights or help will be greatly appreciated!
Thank you

[FrankC2017]

OK, figured it out.
Here is a quick recap.

Issue:
I kept on getting warning message:... \anaconda3\envs\py3-10-6\lib\site-packages\langchain_core_api\deprecation.py:117: LangChainDeprecationWarning: The class langchain_community.embeddings.openai.OpenAIEmbeddings was deprecated in langchain-community 0.1.0 and will be removed in 0.2.0. An updated version of the class exists in the langchain-openai package and should be used instead. To use it run pip install -U langchain-openai and import as from langchain_openai import OpenAIEmbeddings.

Although I followed the instruction as the warning message suggested and the above discussion mentioned, i.e. "To use it run pip install -U langchain-openai and import as from langchain_openai import OpenAIEmbeddings.", the warning message still there when I run my langchain app.

Cause of the issue:
My code does not directly use/call OpenAIEmbeddings, instead, it use VectorstoreIndexCreator which is imported from from langchain.indexes, which has "from langchain_community.embeddings.openai import OpenAIEmbeddings", which caused the warning message issue. (note: I have upgraded langchain to 0.1.0 )

Solution:
I hacked langchain 0.1.0 indexes, updated vectorstore.py to replace "from langchain_community.embeddings.openai import OpenAIEmbeddings" with "from langchain_openai import OpenAIEmbeddings" It resolved the warning message.

Guess langchain0.2.0 will/should resolve these inconsistent package issue.

Summary:
The warning message and its suggestion are correct. To remove warning message, just need find the right code file to replace "from langchain_community.embeddings.openai import OpenAIEmbeddings" by "from langchain_openai import OpenAIEmbeddings" after you do "pip install -U langchain-openai". The code file could be the one your developed, or the one you imported.

Great!
Isn't it considered a bug/something that needs to be updated for VectorstoreIndexCreator (or is that something that will be updated in the next version?) I encountered this issue when using VectorstoreIndexCreator as well.

Hi,

I was facing similar warning issue and tried the solution given above. i.e.

Solution: I hacked langchain 0.1.0 indexes, updated vectorstore.py to replace "from langchain_community.embeddings.openai import OpenAIEmbeddings" with "from langchain_openai import OpenAIEmbeddings

But im getting below error now, can any expert help me here.

-Thank you

[abhishekc-bhs]

Simiar issue cluttering the console and the QA team is furious. Any fixes is highly appreciated :)

[ichenhua]

how to ignore the warning info?

[abhishekc-bhs]

Mine got fixed. Please share your log. will update you with the fix :)

[ichenhua]

the main.py，I set a blocking alert, but it's not working。

import warnings
warnings.filterwarnings("ignore")

loader = CSVLoader(file_path)```

the warning info:

/opt/anaconda3/lib/python3.9/site-packages/langchain/document_loaders/init.py:37: LangChainDeprecationWarning: Importing document loaders from langchain is deprecated. Importing from langchain will no longer be supported as of langchain==0.2.0. Please import from langchain-community instead:

from langchain_community.document_loaders import CSVLoader.

My langchain version is 0.1.14, langchain update is too fast, I don't want to keep running behind, temporarily shield this error。

[FrankC2017]

Hi, @yardenmezi , yes, it is likely a bug in langchain0.1.0. Assume langchain will fix it in a next version, e.g. 0.2.0. hope so.

Hi, @Ba40M , @abhishekc-bhs , both of you have the same warning message issue. To fix it, 1) follow the suggestions in the warning message, do pip install for all the new required packages, and update your code for "from.....import.." accordingly; 2) after that, you should see much less warning messages, if not zero warning message. If you still see some warning messages left, check your code to see any langchain lib code your code access may cause the warning message. Basically, while langchain reminds us/developers not to use some deprecated packages, but langchain forgets to do the same in some of its code. we have do it for langchain in its v0.1.0. Hope it is helpful. Thank you.

[Kaburu12]

I'm encountering same issue :

" LangChainDeprecationWarning: The class langchain_community.embeddings.openai.OpenAIEmbeddings was deprecated in langchain-community 0.1.0 and will be removed in 0.2.0. An updated version of the class exists in the langchain-openai package and should be used instead. To use it run pip install -U langchain-openai and import as from langchain_openai import OpenAIEmbeddings. "

I've exactly followed the steps but I'm still experincing same issues.

I'm currently working with langchain-0.1.9 version and Python 3.8.10 version. Any assistance to fix this issues I'll appreciate.

[FrankC2017]

Pls refer to my answer/posted on Jan 30 above. hope it will help. Thank you.

I'm encountering an issue:

I am currently working with langchain-0.3.4 and python version 3.12. I would assistance to fix my issue

I also encountered this problem, but after consulting a considerable amount of documentation, I couldn't find a solution.
