When I started to train some neural network, it met the CUDA_ERROR_OUT_OF_MEMORY
but the training could go on without error. Because I wanted to use gpu memory
I was experienced memory error in Ubuntu 18.10. When i changed resolution of my monitor from 4k to fullhd (1920-1080) memory available become 438mb and neural network training started. I was really surprised by this behavior.
By the way, i have Nvidia 1080 with 8gb memory, still dont know why only 400mb available
