Hi, I encountered exactly the same problem. Does anyone have any idea what's 
the problem? 

The command I used to compile the dll files is:
nvcc -o libcudamat.dll --shared cudamat.cu cudamat_kernels.cu -LC:\CUDA\lib 
-lcublas

Has anyone used this package on windows? How did you compile it? 

Thanks!

Problem solved. Just add __declspec(dllexport) to all the functions in 
cudamat.cu I got 3 tests failed but reducing the error threshold to 10**-2 
removed those errors. So I don't know if that is fine.

Hi,

After the last suggestion I had tried to change the cudamat.py 
line 7 to
_cudamat = ct.cdll.LoadLibrary('libcudamat.dll')
I think this is the vital problem for running on the windows.
