/app/ 'numpy.ndarray' 对象的 AttributeError 没有属性 'read'

Question

I am making a wep app for face recognition by django and face_recogntion api, I don't how to solve this error

from django.http import HttpResponse
from django.shortcuts import redirect, render
from .models import *
import face_recognition
import cv2
import urllib.request
import numpy as np
import dlib
def Home(request):
    print(f'request method is {request.method}')
    if(request.method=='GET'):
        return render(request, "app.html")
    elif(request.method=='POST'):
        print(f'printing req body {request.POST["imageURL"]}')
        imageURL = urllib.request.urlopen(request.POST["imageURL"])
        imageURL = face_recognition.load_image_file(imageURL)
        image = face_recognition.load_image_file(imageURL)
        image = cv2.cvtColor(image,cv2.COLOR_BGR2RGB)
        imgLoc = face_recognition.face_locations(image);
        print(f'Image imagLoc {imgLoc}')
        cv2.imshow(image)
        cv2.waitKey(3000)
        return redirect('/app/')

I am asking question on stackoverflow for the first time so sorry for any mistakes.

Your problem is here:

imageURL = urllib.request.urlopen(request.POST["imageURL"])
imageURL = face_recognition.load_image_file(imageURL)
image = face_recognition.load_image_file(imageURL)

First

 imageURL = face_recognition.load_image_file(imageURL)

Now imageURL has numpy.ndarray type. Then

image = face_recognition.load_image_file(imageURL)

And here you are trying to load image once again passing that numpy.ndarray as an argument instead of passing image file path, ie string. I don't understand why you are trying to load that image twice.
