Signature TypeError when zen wrapping function that accepts Pydantic BaseModel

[siboles]

I'm very new to hydra and hydra-zen, so this could very much be a user issue, but I am experiencing the following.

Code Snippet

from pydantic import BaseModel
from hydra_zen import store, zen
from hydra_zen.third_party.pydantic import pydantic_parser

class Input(BaseModel):
    x: int = 1

def task(input: Input):
    print(input)


if __name__ == "__main__":
    store(task, hydra_defaults=["_self_", {"input": "base"}])
    store(Input, group="input", name="base")
    store.add_to_hydra_store()

    zen(task, instantiation_wrapper=pydantic_parser).hydra_main(
        config_name="task", config_path=None, version_base="1.3"
    )

Expected Behavior

print the instantiated Input model.

Observed Behavior

Thanks for the great bug report. Super easy for me to dig into 👍

Minimal repro of the bug:

from pydantic import BaseModel
from hydra_zen import instantiate, store, builds
from hydra_zen.third_party.pydantic import pydantic_parser

class Input(BaseModel):
    x: int = 1

instantiate(builds(Input, x=1), _target_wrapper_=pydantic_parser)
# raises same error as OP

(Ironic that pydantic's validator can't handle its own types :P)

Here is a temporary workaround:

def my_parser(x):
    if isinstance(target, type) and issubclass(target, BaseModel):
        # this already applies pydantic parsing
        return x
    return pydantic_parser(x)

instantiate(builds(Input, x=1), _target_wrapper_=my_parser)

I will fix pydantic_parser in the next release of hydra-zen
