Pydantic version

[halx]

Hi,

can you please update to Pydantic 2.x? In this way AiZynthFinder can be more easily installed in the same environment as REINVENT (still many complaints about incompatible packages but none of those seem to matter).

route_distances/validation.py then needs to change as follows

type: str = Field(pattern=r"^mol$")  #pydantic.constr(regex=r"^mol$")
# ...
type: str = Field(pattern=r"^reaction$")

Also, pytorch 1.x is a bit old. From our experience it is no problem to update to the most recent version 2.x.

Many thanks,
Hannes.
