Update to Pydantic 2.0

At some point :)

For now you are blocked on this by agent-search. The latest version 0.0.9 still depends on pydantic < 2

Because agent-search (0.0.9) depends on pydantic (>=1.10.13,<2.0.0)
 and no versions of agent-search match >0.0.9,<0.0.10, agent-search (>=0.0.9,<0.0.10) requires pydantic (>=1.10.13,<2.0.0).
So, because langroid depends on both pydantic (2.5.3) and agent-search (^0.0.9), version solving failed.

blocked on this by agent-search.

I'm surprised this is the only blocker (if so, that's a minor one, since agent-search is just an extra and we can work around that)... I was expecting a lot of similar conflicts.

I haven't run into a situation where I had multiple conflicts before so I'm not sure how the Poetry resolver handles this. It's quite possible that it hit the first conflict and quit without reporting the others. So removing agent-search may bring out other conflicts.

Not sure if this is helpful, but here is a glance about langroid dependency on pydantic:
It mainly relies on pydantic version 1.10.13. Here are the multiple paths between "langroid" and "pydantic" version "1.10.13".

1. langroid -> chromadb -> fastapi -> pydantic version "1.10.13"
2. langroid -> chromadb -> pydantic version "1.10.13"
3. langroid -> farm-haystack -> pydantic version "1.10.13"
4. langroid -> farm-haystack -> quantulum3 -> inflect -> pydantic version "1.10.13"
5. langroid -> lancedb -> pydantic version "1.10.13"
6. langroid -> meilisearch -> camel-converter -> pydantic version "1.10.13"
7. langroid -> meilisearch-python-sdk -> camel-converter -> pydantic version "1.10.13"
8. langroid -> meilisearch-python-sdk -> pydantic version "1.10.13"
9. langroid -> openai -> pydantic version "1.10.13"
10. langroid -> pydantic version "1.10.13"
11. langroid -> qdrant-client -> pydantic version "1.10.13"

However, there is this transitive dependency, where some langroid dependencies use pyndantic version 2.5.3. For example, current langroid version 0.1.164 uses openai version 1.7.1, which uses pydantic version 2.5.3
That's why the picture below shows this package isn't imported (the node doesn't have the imported attribute). Here are multiple paths between "langroid" and "pydantic" version "2.5.3".

1. langroid -> chromadb -> fastapi -> pydantic version "2.5.3"
2. langroid -> chromadb -> pydantic version "2.5.3"
3. langroid -> farm-haystack -> quantulum3 -> inflect -> pydantic version "2.5.3"
4. langroid -> lancedb -> pydantic version "2.5.3"
5. langroid -> meilisearch -> camel-converter -> pydantic version "2.5.3"
6. langroid -> meilisearch-python-sdk -> camel-converter -> pydantic version "2.5.3"
7. langroid -> meilisearch-python-sdk -> pydantic version "2.5.3"
8. langroid -> openai -> pydantic version "2.5.3"
9. langroid -> qdrant-client -> pydantic version "2.5.3"

Probably you are wondering why the agent-search wasn't shown in these paths. The API that I'm using for constructing the graph doesn't consider optional dependencies.

[sanders41]

On a quick scan through requirements files it looks like all the other dependencies have pydantic >= 1.x so they allow 2+ also.

I happen to be the maintainer of camel-converter and meilisearch-python-sdk, and one of the meilisearch client maintainers so I know for sure that is the case on those 😄
