OS: Ubuntu 18.04
Others: Opencv, NCCL, CUDA 9.2, CUDNN
NOTE: For Ubuntu 17.04/ 18.04, there's an alternate way to directly install Caffe via apt-get install caffe-cpu and caffe-cuda
I am installing from source so that I can with other caffe algorithms that demand the existence of a CAFFE_ROOT directory
Modify Makefile.config file

(1) In my case, I found on 18.04 "sudo apt-get install libboost-all-dev" doesn't work:
syu@VAN-2000-NEW:~$ sudo apt-get install libboost-all-dev
