ckpt

from tensorflow.python import pywrap_tensorflow checkpoint_path = 'model.ckpt-8000' reader = pywrap_tensorflow.NewCheckpointReader(checkpoint_path) var_to_shape_map = reader.get_variable_to_shape_map() for key in var_to_shape_map:  print("tensor_name: ", key)

pb

import tensorflow as tfimport osmodel_name = './mobilenet_v2_140_inf_graph.pb'def create_graph(): with tf.gfile.FastGFile(model_name, 'rb') as f:  graph_def = tf.GraphDef()  graph_def.ParseFromString(f.read())  tf.import_graph_def(graph_def, name='')create_graph()tensor_name_list = [tensor.name for tensor in tf.get_default_graph().as_graph_def().node]for tensor_name in tensor_name_list: print(tensor_name,'\n')

ckpt转pb

def freeze_graph(input_checkpoint,output_graph): ''' :param input_checkpoint: :param output_graph: PB模型保存路径 :return: ''' output_node_names = "xxx" saver = tf.train.import_meta_graph(input_checkpoint + '.meta', clear_devices=True) graph = tf.get_default_graph() input_graph_def = graph.as_graph_def() with tf.Session() as sess:  saver.restore(sess, input_checkpoint)  output_graph_def = graph_util.convert_variables_to_constants(    sess=sess,   input_graph_def=input_graph_def,# 等于:sess.graph_def   output_node_names=output_node_names.split(","))  with tf.gfile.GFile(output_graph, "wb") as f:   f.write(output_graph_def.SerializeToString())   print("%d ops in the final graph." % len(output_graph_def.node))    for op in graph.get_operations():   print(op.name, op.values())
