Tensorflow Resource exhausted without no resource exhausted

i'm training an LSTM on my GTX 1060 6gb using Tensorflow 1.2 in python.

On each epoch i save the model with this method:

def save_model(self,session,epoch,save_model_path):

    save_path = self.saver.save(session, save_model_path + "lstm_model_epoch_" + str(epoch) + ".ckpt")
    print("Model saved in file: %s" % save_path)

Everything works but after nine epoch i get ResourceExhaustedError when i try to save the model with this method.

I have checked my resources during the training but no resources are exhausted.

The error that i get is the following:

2017-06-29 12:43:02.865845: W tensorflow/core/framework/op_kernel.cc:1158] Resource exhausted: log/example_0/lstm_models/lstm_model_epoch_9.ckpt.data-00000-of-00001.tempstate10865381291487648358 Traceback (most recent call last): File "main.py", line 32, in File "/home/alb3rto/Scrivania/Tesi/sentiment_classification/text_lstm/LSTM_sentence.py", line 306, in train_lstm File "/home/alb3rto/Scrivania/Tesi/sentiment_classification/text_lstm/LSTM_sentence.py", line 449, in save_model File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 1472, in save File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 789, in run File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 997, in _run File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 1132, in _do_run File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/client/session.py", line 1152, in _do_call tensorflow.python.framework.errors_impl.ResourceExhaustedError: log/example_0/lstm_models/lstm_model_epoch_9.ckpt.data-00000-of-00001.tempstate10865381291487648358 [[Node: save/SaveV2 = SaveV2[dtypes=[DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT], _device="/job:localhost/replica:0/task:0/cpu:0"](_arg_save/Const_0_0, save/SaveV2/tensor_names, save/SaveV2/shape_and_slices, Variable/_21, Variable/Adam/_23, Variable/Adam_1/_25, Variable_1/_27, Variable_1/Adam/_29, Variable_1/Adam_1/_31, beta1_power/_33, beta2_power/_35, rnn/basic_lstm_cell/bias/_37, rnn/basic_lstm_cell/bias/Adam/_39, rnn/basic_lstm_cell/bias/Adam_1/_41, rnn/basic_lstm_cell/kernel/_43, rnn/basic_lstm_cell/kernel/Adam/_45, rnn/basic_lstm_cell/kernel/Adam_1/_47)]] Caused by op u'save/SaveV2', defined at: File "main.py", line 28, in lstm_sentence = lstm() File "/home/alb3rto/Scrivania/Tesi/sentiment_classification/text_lstm/LSTM_sentence.py", line 18, in init File "/home/alb3rto/Scrivania/Tesi/sentiment_classification/text_lstm/LSTM_sentence.py", line 117, in build_lstm File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 1139, in init self.build() File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 1170, in build restore_sequentially=self._restore_sequentially) File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 689, in build save_tensor = self._AddSaveOps(filename_tensor, saveables) File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 276, in _AddSaveOps save = self.save_op(filename_tensor, saveables) File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/training/saver.py", line 219, in save_op tensors) File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/ops/gen_io_ops.py", line 745, in save_v2 File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/framework/op_def_library.py", line 767, in apply_op File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 2506, in create_op original_op=self._default_original_op, op_def=op_def) File "/home/alb3rto/anaconda2/envs/tesi/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 1269, in init self._traceback = _extract_stack() ResourceExhaustedError (see above for traceback): log/example_0/lstm_models/lstm_model_epoch_9.ckpt.data-00000-of-00001.tempstate10865381291487648358 [[Node: save/SaveV2 = SaveV2[dtypes=[DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT], _device="/job:localhost/replica:0/task:0/cpu:0"](_arg_save/Const_0_0, save/SaveV2/tensor_names, save/SaveV2/shape_and_slices, Variable/_21, Variable/Adam/_23, Variable/Adam_1/_25, Variable_1/_27, Variable_1/Adam/_29, Variable_1/Adam_1/_31, beta1_power/_33, beta2_power/_35, rnn/basic_lstm_cell/bias/_37, rnn/basic_lstm_cell/bias/Adam/_39, rnn/basic_lstm_cell/bias/Adam_1/_41, rnn/basic_lstm_cell/kernel/_43, rnn/basic_lstm_cell/kernel/Adam/_45, rnn/basic_lstm_cell/kernel/Adam_1/_47)]]

How can I fix it?

When encountering OOM or ResourceExausted Error on GPU I believe changing(Reducing) batch size is the right option to try at first.

For different GPU you may need different batch size based on the GPU memory you have.

Recently I faced the similar type of problem, tweaked a lot to do the different type of experiment.

Here is the link to the question (also some tricks are included).

However, while reducing the size of the batch you may find that your training gets slower. So if you have multiple GPU you may use them. To check about your GPU you can write on the terminal,

nvidia-smi

It will show you necessary information about your gpu rack.
