rylativity dbf9986d44 langchain-ollama (partners) / langchain-core: allow passing ChatMessages to Ollama (including arbitrary roles) (#30411) ... Replacement for PR #30191 (@ccurme) **Description**: currently, ChatOllama [will raise a value error if a ChatMessage is passed to it](https://github.com/langchain-ai/langchain/blob/master/libs/partners/ollama/langchain_ollama/chat_models.py#L514), as described https://github.com/langchain-ai/langchain/pull/30147#issuecomment-2708932481. Furthermore, ollama-python is removing the limitations on valid roles that can be passed through chat messages to a model in ollama - https://github.com/ollama/ollama-python/pull/462#event-16917810634. This PR removes the role limitations imposed by langchain and enables passing langchain ChatMessages with arbitrary 'role' values through the langchain ChatOllama class to the underlying ollama-python Client. As this PR relies on [merged but unreleased functionality in ollama-python]( https://github.com/ollama/ollama-python/pull/462#event-16917810634), I have temporarily pointed the ollama package source to the main branch of the ollama-python github repo. Format, lint, and tests of new functionality passing. Need to resolve issue with recently added ChatOllama tests. (Now resolved) **Issue**: resolves #30122 (related to ollama issue https://github.com/ollama/ollama/issues/8955) **Dependencies**: no new dependencies [x] PR title [x] PR message [x] Lint and test: format, lint, and test all running successfully and passing --------- Co-authored-by: Ryan Stewart <ryanstewart@Ryans-MacBook-Pro.local> Co-authored-by: Chester Curme <chester.curme@gmail.com>		2025-04-18 10:07:07 -04:00
