Hello,
I have just installed pycuda on a new machine running anaconda3 and cuda
10.1.243_426 for Windows 10, and tested the installation by running a program
that had been run successfully on another machine, but with anaconda2.
My program breaks on a call for gpuarray.zeros, following a call to
gpuarray.to_gpu (no other calls to pycuda have been made before that). Both
calls are trying to establish 2D arrays of dtype=np.float32.
The included headers are:
import pycuda.driver as cuda
import pycuda.tools
import pycuda.autoinit
import pycuda.gpuarray as gpuarray
from pycuda.compiler import SourceModule
I've attached the error trace from python below. I'll be grateful if you could
offer an explanation/fix.
Many thanks,
-Dan
