Arrayfire Installation Error.

[phyce]

Hello, I've been trying to install the free version of arrayfire for python. when i try to install, I get this error:

Traceback (most recent call last):
File "C:\Users\user\Desktop\arrayfire\python\setup.py", line 33, in <module>
CUINC = CUDIR + INC
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

It appears that CUDIR = os.getenv('CUDA_PATH') doesn't work fine. What's the dir it should be pointing at? I got the latest version of Nvidia CUDA SDK installed.
the location of the CUDA SDK is:
'C:\Users\user\AppData\Local\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.2'

Hi Phyce,

You need to install the CUDA toolkit. The cuda sdk is different from the toolkit required for ArrayFire.

Right now we dont support cuda 4.2 toolkit, so you will need to download it from the following location
