Getting error: Cannot reshape array of size 122304 into shape (52,28,28)

Question

I\'m trying to reshape a numpy array as:

data3 = data3.reshape((data3.shape[0], 28, 28))

where data3 is:

[[54          


        

Answer 1

First, your input image's number of elements should match the number of elements in the desired feature vector.

Assuming the above is satisfied, the below should work:

# Reading all the images to a one numpy array. Paths of the images are in the imagePaths
data = np.array([np.array(cv2.imread(imagePaths[i])) for i in range(len(imagePaths))])

# This will contain the an array of feature vectors of the images
features = data.flatten().reshape(1, 784)
