这是我第一次使用张量流，我想尝试验证码解决方案，我在互联网上发现，但我得到了一个错误教程链接https://pylessons.com/TensorFlow-CAPTCHA-final-detection/
TypeError: ParseFromString()缺少1个必需的位置参数:'serialized'
这是我的代码
# Load a (frozen) Tensorflow model into memory.
label_map = label_map_util.load_labelmap(PATH_TO_LABELS)
categories = label_map_util.convert_label_map_to_categories(label_map, max_num_classes=NUM_CLASSES, use_display_name=True)
category_index = label_map_util.create_category_index(categories)
detection_graph = tf.Graph()
with detection_graph.as_default():
od_graph_def = tf.GraphDef
with tf.gfile.GFile(PATH_TO_FROZEN_GRAPH, 'rb') as fid:
serialized_graph = fid.read()
od_graph_def.ParseFromString(serialized_graph)
tf.import_graph_def(od_graph_def, name='')
如果你使用的是tensorflow版本>= 2.0，那么上面的代码将不起作用。下面是更新后的代码，将在tensorflow版本>2.0
with detection_graph.as_default():
od_graph_def = tf.compat.v1.GraphDef()
with tf.compat.v1.gfile.GFile(PATH_TO_FROZEN_GRAPH, 'rb') as fid:
serialized_graph = fid.read()
od_graph_def.ParseFromString(serialized_graph)
tf.compat.v1.import_graph_def(od_graph_def, name='')
