我收到此錯誤如何解決 AttributeError: 'tuple' object has no attribute 'setInput'？

Question

我導入了一張圖片，一切正常，但在運行net.setInput(blob)時出現AttributeError 。

import numpy as np
import cv2

#load the image
img=cv2.imread(r"E:\Face recognition\3_FaceDetection_FeatureExtraction\images\faces.jpg")

cv2.imshow('faces',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
print(img)
net = cv2.dnn.readNetFromCaffe("E:/Face recognition/Models/deploy.prototxt.txt"),("E:/Face recognition/Models/res10_300x300_ssd_iter_140000_fp16.caffemodel")

#extract blob
blob = cv2.dnn.blobFromImage(img, 1, (300,300), (104,177,123), swapRB=False)
net.setInput(blob)

AttributeError                            Traceback (most recent call last)
Input In [6], in <cell line: 1>()
----> 1 net.setInput(blob)

AttributeError: 'tuple' object has no attribute 'setInput'

Answer 1

正如@Dan Mašek在他的評論中提到的，關鍵是

net = cv2.dnn.readNetFromCaffe("E:/Face recognition/Models/deploy.prototxt.txt"),("E:/Face recognition/Models/res10_300x300_ssd_iter_140000_fp16.caffemodel")

逗號使net成為一個元組，其中包含 function 調用cv2.dnn.readNetFromCaffe("E:/Face recognition/Models/deploy.prototxt.txt")和字符串"E:/Face recognition/Models/res10_300x300_ssd_iter_140000_fp16.caffemodel" 。 這相當於

>>> a = 4, "abc"
>>> a
(4, 'abc')
>>> type(a)
tuple

在最后一行中，您調用net.setInput(blob)但元組沒有屬性或方法setInput ，這就是您收到錯誤的原因。

可能，您想編寫net = cv2.dnn.readNetFromCaffe("E:/Face recognition/Models/deploy.prototxt.txt", "E:/Face recognition/Models/res10_300x300_ssd_iter_140000_fp16.caffemodel")或簡單地net = cv2.dnn.readNetFromCaffe("E:/Face recognition/Models/deploy.prototxt.txt") （我不知道方法readNetFromCaffe ，所以我不知道它需要什么作為輸入）。
