Unable to load image

Question

I cannot change an image from web to an array.

Can anyone help?

Thank you very much.

from PIL import Image
from io import BytesIO
import requests
import numpy as np

url =r'https://drive.google.com/uc?id=1xrKyFZAIIR_XVhlhYGHlfLvIr5vQ5EnW'
img = Image.open(BytesIO(requests.get(url).content))
arr = np.array(img, dtype = np.uint8)

Traceback (most recent call last):
  File "<pyshell#78>", line 1, in <module>
    arr = np.array(img, dtype = np.uint8)
TypeError: int() argument must be a string, a bytes-like object or a number, not 'JpegImageFile'

Download the image and save it in .jpg format. Try 'imread' command from Scipy library. — spectre, May 25 '18 at 14:48
Do you have an error ? which one ? I guess it depends on the image format — smaftoul, May 25 '18 at 14:49
This is really weird... calling `np.array(img, dtype = np.uint8)` throws a ValueError the first time, but if you try it again it works... — Aran-Fey, May 25 '18 at 15:05
Do you want to convert the raw bytes of the image file, or the decoded image data (RGB values) to an array? — mkrieger1, May 25 '18 at 15:17

@spectre I have lots of images to process. Downloading them will take a long time — John, May 25 '18 at 18:15
@Mark Thank you for your help. What is the problem of my original code? — John, May 25 '18 at 18:18

Thank you for the help of Mark. The solution to this problem is:

import cv2
import requests
import numpy as np

url =r'https://drive.google.com/uc?id=1xrKyFZAIIR_XVhlhYGHlfLvIr5vQ5EnW'
resp = requests.get(url).content
image = np.asarray(bytearray(resp), dtype="uint8")
arr = cv2.imdecode(image, cv2.IMREAD_COLOR)
