Question

当前，我正在进行面部识别，并且给定的代码存在以下问题。

for i in range(nrof_faces):
    emb_array = np.zeros((1, embedding_size))

    bb[i][0] = det[i][0]
    bb[i][1] = det[i][1]    
    bb[i][2] = det[i][2]
    bb[i][3] = det[i][3]

    # inner exception
    if bb[i][0] <= 0 or bb[i][1] <= 0 or bb[i][2] >= len(frame[0]) or bb[i] 
        [3] >= len(frame):
        print('Face is very close!')
        continue

    cropped.append(frame[bb[i][1]:bb[i][3], bb[i][0]:bb[i][2], :])
    cropped[i] = facenet.flip(cropped[i], False)
    scaled.append(misc.imresize(cropped[i], (image_size, image_size), 
             interp='bilinear'))
    scaled[i] = cv2.resize(scaled[i], (input_image_size,input_image_size),
                       interpolation=cv2.INTER_CUBIC)
    scaled[i] = facenet.prewhiten(scaled[i])

scaled_reshape.append（scaled [i] .reshape（-1，input_image_size，input_image_size，3））

    feed_dict = {images_placeholder: scaled_reshape[i], phase_train_placeholder: False}
    emb_array[0, :] = sess.run(embeddings, feed_dict=feed_dict)
    predictions = model.predict_proba(emb_array)
    print(predictions)

这给了我以下错误：

Traceback (most recent call last):
File "F:\std\programs\python\Camera\Facenet-Real-time-face-recognition-using-deep-learning-Tensorflow\test_video.py", line 107, in <module>
  predictions = model.predict_proba(emb_array)

  (n_features, self.shape_fit_[1]))
ValueError: X.shape[1] = 128 should be equal to 512, the number of features at training time

ValueError：X.shape [1] = 128应该等于512，即训练时的特征数量
