Hallo, ich mit einem YouTube video eine kleine FastApi App geschrieben. Dann habe ich sie als ein Docker gebaut. Wenn ich diesen nun starte bekomme ich die im Titel stehende Fehlermeldung. `Ich habe schon ganz Google nach einer Möglichkeit durchgesucht aber leider keine Lösung gefunden. Vll. hat ja einer von euch 'ne Idee.

DER CODE:

from fastapi import FastAPI
from app.model.test import Upscale

app = FastAPI()

class TextIn(Upscale):
    org_url: str


class TextOut(Upscale):
    url: str



@app.get("/")
def home():
    return {"health_check": "OK"}

@app.post("/post", response_model=TextOut)
def UpSc(payload: TextIn):
    textwrap = Upscale(payload.org_url)
    return {"url": "url"}

`

KOMPLETTER TRACEBACK: `

in meinen requirements.txt steht:

fastapi
boto3
opencv-contrib-python-headless
opencv-python-headless
numpy

ich nutzte Python 3.9 habe es aber auch ohne Erfolg mit anderen Version probiert.
