Tensorflow: 从checkpoint文件中读取tensor方式

import os
from tensorflow.python import pywrap_tensorflow

checkpoint_path = os.path.join(model_dir, "model.ckpt")
# Read data from checkpoint file
reader = pywrap_tensorflow.NewCheckpointReader(checkpoint_path)
var_to_shape_map = reader.get_variable_to_shape_map()
# Print tensor name and values
for key in var_to_shape_map:
 print("tensor_name: ", key)
 print(reader.get_tensor(key))
