deeppy/cudarray can't find CUDA device anymore

[genekogan]

installed cudarray, added /usr/local/lib/ to LD_LIBRARY_PATH, and cuda (/usr/local/cuda-6.5/lib64/) to PATH, but when i run this in python:

import os
os.environ['CUDARRAY_BACKEND'] = 'cuda'
import deeppy

i get this traceback.

CUDArray: Failed to load CUDA back-end. Traceback (most recent call last): File "", line 1, in File "build/bdist.linux-x86_64/egg/deeppy/init.py", line 9, in File "build/bdist.linux-x86_64/egg/deeppy/dataset/init.py", line 2, in File "build/bdist.linux-x86_64/egg/deeppy/dataset/infimnist.py", line 6, in File "build/bdist.linux-x86_64/egg/deeppy/base.py", line 1, in File "/usr/local/lib/python2.7/dist-packages/cudarray-0.1.dev-py2.7-linux-x86_64.egg/cudarray/_ init_.py", line 29, in wrap.cudart.initialize(_gpu_id) File "cudarray/wrap/cudart.pyx", line 4, in cudarray.wrap.cudart.initialize (./cudarray/wrap/cu dart.cpp:671) File "cudarray/wrap/cudart.pyx", line 5, in cudarray.wrap.cudart.initialize (./cudarray/wrap/cu dart.cpp:600) File "cudarray/wrap/cudart.pyx", line 12, in cudarray.wrap.cudart.cudaCheck (./cudarray/wrap/cu dart.cpp:736) ValueError: no CUDA-capable device is detected

this worked a few months ago -- could there be a problem between recent commits of deeppy/cudarray and cuda-6.5? not exactly sure where this problem is coming from.

thanks!

Hi! I haven't seen this before. I can't think of any changes that should cause such problems. Have you remembered to clean up the CUDArray folder with both make clean and python setup.py clean before the new installation? Also, make sure that the environment variable CUDARRAY_DEVICE is the correct id of your GPU (default is '0').

A brief web search on the error message also suggests this and this.

@genekogan, have you had any luck troubleshooting this issue? I'm getting something similar on an AWS instance:

import os os.environ['CUDARRAY_BACKEND'] = 'cuda' import cudarray CUDArray: Failed to load CUDA back-end.
