Hi - I am trying to run VGG16 over 8000+ 224x224 images, batch size 32, 15 epochs.

The iterations do not begin, giving the following error:

Exception in thread “main” java.lang.RuntimeException: Failed to allocate 2027570444 bytes from DEVICE [0] memory

GPU: NVIDIA GTX 060, 6GB  
GPU Intel HD Graphics 630  
24GB RAM (13 GB of which is available)  
Intel Core 7th Gen

I have been trying to see detailed documentation on CUDNN and CUDA settings but haven’t found any details. Could you please help me figuring what the issue could be?

P.S: I have been able to run a similar VGG16 for a similar set of images on this same machine on Keras-GPU. It works perfectly.

Take a look at [https://deeplearning4j.konduit.ai/config/config-memory#configuring-memory-limits](https://deeplearning4j.konduit.ai/config/config-memory#configuring-memory-limits)

And configure more actual memory to be used. As you can see in the log snippet you’ve posted it will only use up to 5.3GB of memory.
