I have python3 3.6.9 on Kubuntu 18.04. I have installed fastapi using pip3 install fastapi. I'm trying to test drive the framework through its official documentation and I'm in the relational database section of its guide.
In schemas.py:
from typing import List
from pydantic import BaseModel
class VerseBase(BaseModel):
AyahText: str
NormalText: str
class Verse(VerseBase):
id: int
class Config:
orm_mode = True
VS code highlights an error in from pydantic import BaseModel and it tells that: No name 'BaseModel' in module 'pydantic'. Additionally, when I try to run uvicorn main:app reload I have gotten the following error:
File "./main.py", line 6, in <module> from . import crud, models, schemas ImportError: attempted relative import with no known parent package
I have tried to renstall pydantic using pip3 but it tells me that:
Requirement already satisfied: dataclasses>=0.6; python_version < "3.7" in ./.local/lib/python3.6/site-packages (from pydantic) (0.7)
The problem of highlighting in VS code may be a problem due to the fact that you did not open the folder. It's quite annoying as it happens often to me as well (and I have basically your same config).
Regarding the second problem you mention, it is probably due to the fact that the folder in which the script lays, does not have a __init__.py file. If you add it, it should work since python will interpret the folder as a module.
As an alternative, you could try to import with the full path from the top folder (e.g. from app.module.main import app).
