Traceback (most recent call last):
File "E:/tensorflow_face_recognition-master/get_features_into_csv_tensorflow.py", line 114, in
pnet,rnet,onet=align.detect_face.create_mtcnn(sess,None) #加载MTCNN的3层网络，用来检测人脸
File "E:\tensorflow_face_recognition-master\align\detect_face.py", line 280, in create_mtcnn
with tf.variable_scope('pnet'):
AttributeError: module 'tensorflow' has no attribute 'variable_scope'
报错最后面显示没有variable_scope，在网上没有找到答案
