PermissionDeniedError when save model

zzeric commented 7 years ago

System information

Have I written custom code (as opposed to using a stock example script provided in TensorFlow):
**OS Platform and Distribution: Win7
TensorFlow installed from (source or binary): pip
TensorFlow version (use command below): tensorflow-gpu 1.3.0
Python version: python 3.6 64bit
CUDA/cuDNN version: 8.0/6.0
GPU model and memory: GTX 1050Ti 4GB
Describe the problem

try to load a model and then save it, same codes ran in three computers，one failed when saving (tensorflow-gpu 1.3.0 GTX 1050Ti 4GB), another two passed (tensorflow 1.3.0 and tensorflow-gpu 1.3.0 with GTX 780 Ti 4GB) . And I ran it as Administrator, so should not lack of write permission

here is the code ` def fit(self, training_iters =1e2, learning_rate = 1e-4, optimizer_epsilon = 1e-10, max_gard_norm = 50, display_step = 5, save_path = None, restore_path = None):

    self._sess.run(tf.global_variables_initializer())
    self._variables_saver = tf.train.Saver()
    if restore_path is not None and os.path.exists(restore_path):
        self._variables_saver.restore(self._sess, restore_path)
        print ('restore ok')

    if self._batch_size == self._mini_batch_size:
        for scope in range(np.int(training_iters)):
            _, loss, acc, tp1, tp2 = \
            self._sess.run([self._train_step, self._cost, self._accuracy, self._pondering_cost, self._rnn_cost],
                           feed_dict = {self._inputs:self._tmp_inputs, self._targets:self._tmp_targets})

            if scope % display_step == 0:
                print (scope, '  loss--', loss, '  acc--', acc, '  pondering_cost--',tp1, '  rnn_cost--', tp2)
                if save_path is not None:
                    self._variables_saver.save(self._sess, save_path)`

It looks like your save path is invalid

4 save_path="e:./dnc_model_171.ckpt",

try giving it one that isn't a mix of being relative and absolute.

I have encountered the same problem，and the problem is caused by that I save the model file in the same path which I put the Python file. When I save the model file in a different path from the path of python file, the problem is solved. Good luck!
