macos - M1 MAC 的 opencv 问题 - OpenCV imshow 不起作用

Question

我购买了 M1 Mac。有人对 imshow with opencv 有问题吗？我做了 pip install opencv-python 和 brew install opencv 以及 brew install opencv。

import cv2
import urllib
import numpy as np
import requests
url = 'https://www.visitcalifornia.com/sites/visitcalifornia.com/files/styles/welcome_image/public/vc_crtr_borntobewild_module_mendocino_st_rf_623667652_1280x640.jpg'
from skimage import io
img = io.imread(url)
img = cv2.cvtColor(img, cv2.COLOR_RGB2BGR)
cv2.imshow('URL Image', img)
cv2.waitKey()

还有

import cv2

cv2.namedWindow("preview")
vc = cv2.VideoCapture(0)

if vc.isOpened(): # try to get the first frame
    rval, frame = vc.read()
else:
    rval = False

while rval:
    cv2.imshow("preview", frame)
    rval, frame = vc.read()
    key = cv2.waitKey(20)
    if key == 27: # exit on ESC
        break

cv2.destroyWindow("preview")
vc.release()

不适合我
