This can happen sometimes when you are running low on GPU memory due to a bug. You will be receiving the "GPULowOnMemory" warning "GPU is low on memory, which can slow performance due to additional data transfers with main memory. Try reducing the 'MiniBatchSize' training option."

The solution is to reduce your mini-batch size. You will find that training goes faster.
