I am facing some compilation errors when I compile the given cuda-extension tutorial code from here:
CUDA version : 9.0
gcc version : 6.4.0
Pytorch version : 1.0.0.dev20181008 / 0.5.0a0+ab6afc2
Compilation log:
The notable errors are:

The code is taken from the given pytorch cpp extension github repo as it is.
I had to make a change to replace fmax() to fmaxf() (in this line) for the code to compile though.
