Cuda not showing output in Google collab

[Bk8]

I'm using this code, to prepare the environment

!/usr/local/cuda/bin/nvcc --version
!gcc-5 -v
!pip install git+git://github.com/andreinechaev/nvcc4jupyter.git
%load_ext nvcc_plugin
!rm /usr/bin/gcc
!rm /usr/bin/g++
!ln -s /usr/bin/gcc-5 /usr/bin/gcc
!ln -s /usr/bin/g++-5 /usr/bin/g++

Then when I try to run this simple example:

%%cu
#include <stdio.h>

void helloCPU()
{
  printf("Hello from the CPU.\n");
}

/*
 * The addition of `__global__` signifies that this function
 * should be launced on the GPU.
 */

__global__ void helloGPU()
{
  printf("Hello from the GPU.\n");
}

int main()
{
   helloCPU();


  /*
   * Add an execution configuration with the <<<...>>> syntax
   * will launch this function as a kernel on the GPU.
   */

  helloGPU<<<1, 1>>>();

  /*
   * `cudaDeviceSynchronize` will block the CPU stream until
   * all GPU kernels have completed.
   */

  cudaDeviceSynchronize();
}

It runs but I get the output from the CPU but not the GPU

'Hello from the CPU.\n'

Sorry I was running it without a GPU, now it's working!
Thanks for the great plugin!
