Unable to run "from langchain_openai import ChatOpenAI"

• I added a very descriptive title to this issue.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
• I posted a self-contained, minimal, reproducible example. A maintainer can copy it and run it AS IS.

Description

Up until a few days ago I was able to run the line "from langchain_openai import ChatOpenAI" in my Google Colab notebook but now I'm receiving the error message "ImportError: cannot import name 'convert_to_openai_image_block' from 'langchain_core.messages' (/usr/local/lib/python3.11/dist-packages/langchain_core/messages/init.py)"

Any ideas on what's going wrong and how I can fix it?

Thanks for the report - hmm, I'm unable to reproduce this issue with the versions you've listed above :(. Looking into this further.

[ccurme]

I suspect you are running a version of langchain-core that is lower than the minimum specified by the latest langchain-openai (0.3.52). Can you try:

• Restarting the kernel
• pip install --upgrade langchain-openai (should force an update of langchain-core)
• pip install --upgrade langchain-core

And let me know if that does not resolve the issue?

[Akinola92]

pip install --upgrade langchain-openai & pip install --upgrade langchain-core

Looks to have solved it - Thanks @ccurme !
