pydantic-core dependency conflict

[hirotasoshu]

Running make install results in the following error:

ERROR: Cannot install -r requirements/./pyproject.txt (line 11) and pydantic-core==0.27.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested pydantic-core==0.27.0
    pydantic 2.0a4 depends on pydantic-core==0.31.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
