Reproduction Steps

Run:

from langchain_core.output_parsers.base import BaseOutputParser

Expected Behavior

That single import should work, but it instead raises the following error:

TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'

Additional Context

No response

Suggested Solutions

This isn't a problem of mistral-common per se, it rather comes from the pydantic version 2.6.1, the error has been addressed on pydantic/pydantic#9637 and it's been fixed in version 2.7.4

Related to this other issue: #15, the version specified on the https://github.com/mistralai/mistral-common/blob/main/pyproject.toml should probably be prefixed with a caret such that:

...
python = "^3.8.10"
- pydantic = "2.6.1"
+ pydantic = "^2.7.4"
jsonschema = "4.21.1"
...

This would allow the project being compatible with every pydantic version above 2.7.4 but constrained to that major version number (a version 3 is underway, they will probably change many things of the API, but I haven't checked the specifics yet)

[egeres]

Considering this other issue: #37 it might even be a good idea to directly have the version set as ^2.8.2

[patrickvonplaten]

Thanks a lot for the issue! Think we can leave at ^2.6.1 because mistralai and mistral_common are different packages and ^2.6.1 will always install the lastest version which should be compatible with mistralai

#40 is merged and 1.3.4 is out - let me know if this solves the issue :-)
