Thank you, this is a much better fix (I returned the absolute path, which
worked
for me).
I have gotten pycuda to work with Enthought Python distribution. However, I get
this warning:
Warning (from warnings module):
File "C:\Enthought Python\lib\site-packages\pycuda\compiler.py", line 110
+stdout+stderr)
UserWarning: The CUDA compiler suceeded, but said the following:
kernel.cu
tmpxft_0000158c_00000000-3_kernel.cudafe1.gpu
tmpxft_0000158c_00000000-8_kernel.cudafe2.gpu
Is this something I should be worried about or can I just remove this check
from
compiler? It gives correct results, but this warning always shows up.
When I try using pycuda with Python(x,y), I always get "ImportError: DLL
invalid
memory access" originated from driver.py 1st line: import _driver. But I'm fine
with Enthought's.
Thank you again.
