Thanks! I updated cu package and chage path to cuda lib in my system to drive D:

CUDA version: 9000
CUDA devices: 1
Device 0
========
Name      :	"GeForce GT 740M"
Clock Rate:	895000 kHz
Memory    :	2147483648 bytes
Compute   : 	3.0

Process finished with exit code 0

I think that if we use this approach, it will be very convenient.

Yes! But the problem is that for Windows there is a hard binding to the path, and when installing CUDA, the real path to the library will be written into environment variables.

Oh that's... surprising. What would the solution be then? Making sure everyone set their environment variable is a lot less intuitive, no?

By default, this environment variables is set up by the CUDA toolkit installer itself.

is it always the same? If a user decides to install CUDA elsewhere?

If it's always the same we can hardcode it right?

Thanks! Yes, the installer itself writes the selected path for installation. The default value is
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA
But the first time I had a problem with spaces in the path to the library. (

Sorry to interrupt the conversation here. But when I initially submitted my Pull request and added the other versions of Cuda I did actually try to set the environment flag ($CUDA_PATH/include/) rather then putting an absolute path into the flags. For whatever reason, Cgo had trouble getting the path even through the environment variable at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA. Its possible that my implementation of this didn't work properly for whatever reasons. I didn't try it again after I reset the cuda path to c:\cuda.

Ill try it really quick now if you want and see if that will work. As @kolkov mentioned above, the cuda installer automatically sets up a CUDA_PATH variable on the system so it might be a better solution.

After a quick try, I was unable to make it work. The problem it seems has to do with the difference between bash path variables and windows path variables. Cgo uses the gcc compiler which means it needs to use a bash style syntax to find the variable which would be $CUDA_PATH but windows can't find the variable through that format. Windows needs to use a %CUDA_PATH% format.

I tried putting both %CUDA_PATH% and $CUDA_PATH into the cgoflags.go file with no success. If you are able to find an alternate syntax that would allow this to work then you could remove all of the other version paths for windows since the CUDA_PATH includes the version folder number.

Its not about the spaces so much as its about the windows variable format vs the bash variable format. %CUDA_PATH% and $CUDA_PATH respectively. I guess a different way to handle this would be to add some kind of conditional statement or try/catch block into the comments but I don't know if that's possible with cgo. I'll try to post a question to stack overflow and see what comes up.
