Go to Makefile.config and uncomment CUDA =1. Make sure you have cuda and cudnn installed on your pc or else installation fails. If you have multiple gpus in your pc and want to use multiple gpus uncommment NCCL=1 in Makefile.config( ensure nccl libraries are installed in your pc).
After uncommenting follow the same process you used to install caffe earlier

After editing the Makefile.config, you have to build caffe again using the steps below.
1.make clean
2.make -j8
3.make pycaffe
Have you done this?
