title: Tensorflow OOM on GPU
body: <p>i'm training some Music Data on a LSTM-RNN in Tensorflow and encountered some Problem with GPU-Memory-Allocation which i don't understand: I encounter an OOM when there actually seems to be just about enough VRAM still available. 
  Some background: 
  I'm working on Ubuntu Gnome 16.04, using a GTX1060 6GB, Intel Xeon E3-1231V3 and 8GB RAM. 
  So now first the part of the error-message which i can understand, in the and i will add the whole error message in the end again for anyone who might ask for it to help: </p>

  </blockquote>
  
  <p>So i can read that there is a maximum of 5484118016 bytes to be allocated, 
  4670717952 bytes are allready in use, and another 777.72MB = 775720000 bytes are to be allocated. 5484118016 bytes - 4670717952 bytes - 775720000 bytes = 37680064 bytes according to my calculator. 
  So there should still be 37MB of free VRAM after allocating the space for the new Tensor he wants to push in there. This seems also to be quite legit to me, as Tensorflow would probably (i guess?) not try to allocate more VRAM than there is still available and just put the rest of the data on hold in RAM or something. </p>
  
  <p>Now i guess there is just some big error in my thinking, but i would be quite gratefull if someone could explain to me, what this error is. The obvious solving-strategy to my problem is to just make my batches a bit smaller, having them each at around 1.5GB probably just is too big. Still i would love to know what the actual problem is there. </p>
  
  <p>edit: I found something telling me to try: </p>
  
  <pre><code>config = tf.ConfigProto()
  config.gpu_options.allocator_type = 'BFC'
  with tf.Session(config = config) as s:
  </code></pre>
  
  <p>which still does not work, but as the tensorflow documentation lacks any explanation of what </p>
  
  <pre><code> gpu_options.allocator_type = 'BFC'
  </code></pre>
  
  <p>would be, i would love to ask you guys.</p>
  
  <p>Adding the rest of the error message for anyone interested: </p>
  
  <p>Sorry for the long copy/paste, but maybe someone would need/want to see it, </p>
  
  <p>Thank you so much in advance, 
  Leon</p>
