Alembic создаёт пустые миграции

Проблема: после alembic revision --autogenerate создаётся пустая миграция (модели не подгрузились). Скорее всего, alembic не видит модели. Поэтому я решил все в один файл засунуть, т.е. в wallet_model, но это тоже не помогло.

Файл wallet_model:

from sqlalchemy import Column, Numeric, DateTime, text
from sqlalchemy.dialects.postgresql import UUID
from sqlalchemy.sql import func
from sqlalchemy.orm import declarative_base


# База для моделей
Base = declarative_base()


class Wallet(Base):
    __tablename__ = "wallets"

    id = Column(
        UUID(as_uuid=True),
        primary_key=True,
        server_default=text("gen_random_uuid()")
    )
    balance = Column(
        Numeric(15, 2),
        nullable=False,
        default=0.00,
        server_default="0.00"
    )
    created_at = Column(
        DateTime(timezone=True),
        server_default=func.now()
    )
    updated_at = Column(
        DateTime(timezone=True),
        onupdate=func.now()
    )
