Hmm I don't think this should be required. Could you confirm what happens if you have langchain 1.0.3 and langchain_core 1.0? I'm wondering if maybe langchain_core was a different version?

hi @eyurtsev

what happens if you have langchain 1.0.3 and langchain_core 1.0?

I assume you meant langchain 1.0.3 and langchain_core 1.0.0. Here’s my test setup in a clean environment:

pip install langchain_core===1.0.0
pip install -U langchain

I’m still seeing the same issue: #33770

>>> from langchain.messages import AIMessage
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/mc/.venv-langchaing_test/lib/python3.10/site-packages/langchain/messages/__init__.py", line 12, in <module>
    from langchain_core.messages import (
ImportError: cannot import name 'InputTokenDetails' from 'langchain_core.messages' (/home/mc/.venv-langchaing_test/lib/python3.10/site-packages/langchain_core/messages/__init__.py)

$ pip freeze
...
langchain==1.0.3
langchain-core==1.0.0
...

Is this expected behavior? I have version 1.0.0 installed(both), and when I try to update langchain, it doesn’t update langchain_core:

pip install langchain_core===1.0.0
pip install langchain===1.0.0
pip install -U langchain

$ pip freeze
...
langchain==1.0.3
langchain-core==1.0.0
...
