x and y can be no greater than 2-D, but have shapes (1,) and (1, 224, 224, 3)

问题

I am trying to visualize the prediction of VGG-16 for the cat image, Compute the top-5 scores (the 5 classes with the maximum probability), For each of these 5 scores, print the corresponding label and the corresponding probability.

    from keras.applications.vgg16 import preprocess_input
    from keras.preprocessing import image

    # load the image from cat class and resize it
    img = image.load_img('cat.jpg', target_size=(224, 224))

    # convert to numpy array of (224, 224, 3)
    x = image.img_to_array(img)

    # add empty dimention for tensor flow (1,224,224,3)
    x = np.expand_dims(x, axis = 0)

    # perform mean removal as in the original VGG16 network
    x = preprocess_input(x)

    # make the prediction using VGG16
    output = model.predict(x)
    print('model prediction output', output)

    # plot the prediction
    plt.plot(output[0], '-')
    plt.show()

    # decode the prediction
    from keras.applications.vgg16 import decode_predictions
    top5 = decode_predictions(output)
    for _, label, proba in top5[0]:
    print(label, 'with probability', proba)

I am getting this error any help will be appreciated
