В sqlalchemy откуда импортировать declarative_base? from sqlalchemy import Column, String from sqlalchemy.ext.declarative

import declarative_base
# или надо написать - from sqlalchemy.orm import declarative_base
from sqlalchemy.dialects.mysql import INTEGER

Base = declarative_base()

class ProductCardEntity(Base):
__tablename__ = 'ProductDirectory'
id = Column(INTEGER(unsigned=True), primary_key=True)
name = Column(String(64))
code = Column(String(64), unique=True)
unit = Column(String(32))
price = Column(INTEGER(unsigned=True))
