tensorflow 获取checkpoint中的变量列表实例

reader = tf.train.NewCheckpointReader(model_path)

#reader = pywrap_tensorflow.NewCheckpointReader(model_path)
reader = tf.train.NewCheckpointReader(model_path)
 
## 用reader获取变量字典,key是变量名,value是变量的shape
var_to_shape_map = reader.get_variable_to_shape_map()
for var_name in var_to_shape_map.keys():
 #用reader获取变量值
 var_value = reader.get_tensor(var_name)
 
 print("var_name",var_name)
 print("var_value",var_value)
