URL : https://python.langchain.com/docs/use_cases/extraction Desc: <b> While the following statement executes successfully, it throws an error which is described below when we use the imported packages</b> ```py from pydantic import BaseModel, Field, validator ``` Code: ```python from langchain.output_parsers import PydanticOutputParser from langchain.prompts import ( PromptTemplate, ) from langchain_openai import OpenAI from pydantic import BaseModel, Field, validator # Define your desired data structure. class Joke(BaseModel): setup: str = Field(description="question to set up a joke") punchline: str = Field(description="answer to resolve the joke") # You can add custom validation logic easily with Pydantic. @validator("setup") def question_ends_with_question_mark(cls, field): if field[-1] != "?": raise ValueError("Badly formed question!") return field ``` Error: ```md PydanticUserError: The `field` and `config` parameters are not available in Pydantic V2, please use the `info` parameter instead. For further information visit https://errors.pydantic.dev/2.5/u/validator-field-config-info ``` Solution: Instead of doing: ```py from pydantic import BaseModel, Field, validator ``` We should do: ```py from langchain_core.pydantic_v1 import BaseModel, Field, validator ``` Thanks. --------- Co-authored-by: Bagatur <baskaryan@gmail.com> |
