Tensorflow with gpu

Pre

• check device

~$ lspci | grep NVIDIA
81:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)
81:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1)

• check driver version

~$ modinfo nv[TAB]

• install cuda 9.0 with patches

~$ cat /proc/driver/nvidia/version
