[PyCUDA] PyCuda with Cuda 7.0 on Windows 8.1 installation issues, no module named compyte.dtypes

[Jannes Nagel]

Hi!

I just installed pycuda on my system. I have Windows 8.1 and a GTX970 in
my Notebook. Therefore I am using Cuda 7 as the only compatible Cuda
Version with my system.

I ran into 2 problems and I hope someone can help me.
1: If I enable CURAND I cannot build pycuda. I always get 5 unresolved
external function errors.
Those externals are all related to CURAND and I think this might be
because the CURAND library is not included in the Cuda Win32 Lib folder.

2: Building without CURAND works and installing also works fine.
I get some warnings regarding deprecated NumPy API but that does not
seem to be the problem.

When I try to run one of the example programs from the pycuda wiki (no
matter which) I get an error in:
pycuda\tools.py line 42:
ImportError: No module named compyte.dtypes

I have no idea why this error occurs. Here is my siteconf.py maybe it
helps identifying the problem:
BOOST_INC_DIR = []
BOOST_LIB_DIR = []
BOOST_COMPILER = 'gcc43'
USE_SHIPPED_BOOST = True
BOOST_PYTHON_LIBNAME = ['boost_python-py27']
BOOST_THREAD_LIBNAME = ['boost_thread']
CUDA_TRACE = False
CUDA_ROOT = 'C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v7.0'
CUDA_ENABLE_GL = False
CUDA_ENABLE_CURAND = False
CUDADRV_LIB_DIR = ['${CUDA_ROOT}/lib/Win32', '${CUDA_ROOT}/lib/x64']
CUDADRV_LIBNAME = ['cuda']
CUDART_LIB_DIR = ['${CUDA_ROOT}/lib/Win32', '${CUDA_ROOT}/lib/x64']
CUDART_LIBNAME = ['cudart']
CURAND_LIB_DIR = ['${CUDA_ROOT}/lib/Win32', '${CUDA_ROOT}/lib/x64']
CURAND_LIBNAME = ['curand']
CXXFLAGS = ['/EHsc']
LDFLAGS = []

Thank you very much!

My default suspicion for this would be a mismatch between the CUDA
driver and the CUDA runtime.

I assume you built from git. If so, if you look in your pycuda source
directory, does

pycuda/compyte/dtypes.py

exist? If not, did you clone PyCUDA with its git submodules?

Hope this helps,
