Thank you. Unfortunately, I can't get pygpu to work. I'm on Windows.
I managed to build the dll with VS2013 and I added it to the path ("where
gpuarray.dll" finds the file).
When I run pygpu.test() I get:
EEEEEE
======================================================================
ERROR: Failure: GpuArrayException (Error loading library: -1)

etc...
Any idea what I'm doing wrong?
