Modifying variables names after restoring from checkpoint in TensorFlow












3














let's say I have two models with different configurations. I train and checkpoint them.



def train_and_save_model_using_config1():
...


def train_and_save_model_using_config2():
...


I'd like to load these models in the same session so I can use them at the same time. The variable names are mostly the same for the above two models, so to avoid name mangling, I add a name scope for each model.



with tf.variable_scope("config1"):
m1 = load_model_from_ckpt_with_config1()

with tf.variable_scope("config2"):
m2 = load_model_from_ckpt_with_config2()


To restore from the checkpoint for config1, I collect the variables and variable names but want to rename with the proper scope.



path = get_path_of_config1()
var_names = tf.contrib.framework.list_variables(path)
vars = {}
for name, shape in var_names:
var = tf.contrib.framework.load_variable(path, name)
vars["config1/" + name] = var

saver = tf.train.Saver(var_list=vars)
saver.restore(sess, tf.train.latest_checkpoint(path))


But I get the following error:



TypeError: names_to_saveables must be a dict mapping string names to Tensors/Variables. Not a variable: Tensor("Const:0", shape=(128, 14987), dtype=float32)

The vars dict in saver = tf.train.Saver(var_list=vars) must be a dict whose value is the reference to the tf.Variable of current graph in current session.

But in your case var = tf.contrib.framework.load_variable(path, name), the problem is that var is numpy.ndarray
