该错误只是意味着无法加载/读取图像。是从这条线传来的

img= cv2.imread("/content/drive/My Drive/DL_DATAset/Autotag/Test Image/image100.jpg")

• • 路径：镜像应该在工作目录下，或者给出镜像的完整路径。**

您确定提供了imgread()方法的正确路径吗？尝试给它一个完整的绝对路径，例如。

img= cv2.imread("'C:\Users\User\Desktop\geeksforgeeks.png'")

要解决这个问题，你可以这样做

docs="""yourstring""".split("\n")

docs

w_corp = 0
w_oracle = 0
w_both = 0
for s in docs:
  s_splited = s.split(" ")
  if "ex1" in s_splited:
    w_corp += 1

  if "ex2" in s_splited:
    w_oracle += 1

  if "ex1" in s_splited and "ex2" in s_splited:
    w_both += 1

import math
max(0, math.log2(len(docs) * w_both / (w_oracle * w_corp)))

img = cv2.imread("picture.jpg")

img_rgb = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
