title: Make Error 127 -( obj/convolutioanl_kernels.o) while compiling Yolo (Darknet) with GPU=1
body: <p>System Configuration: Ubuntu 16.04, Nvidia GTX 1060
  Cuda Tool Kit: 9.0</p>
  
  <p>I installed Cuda 9.0 on my system and am able to output nvidia-smi 
  However, when I am trying to make darknet with GPU I am getting the following error:</p>
