PyCUDA installation troubles
by Burdge, Kevin B.
Hi everyone,
I've been struggling to get PyCUDA up and running on my new machine (Ubuntu 16.04, using latest python 3 anaconda distro as python). I can get the configure and install to run without any hiccups, and have sorted out the path to the CUDA directory, but I inevitably keep arriving at the following error when I try and run the test script:
python test_driver.pyTraceback (most recent call last):
File "test_driver.py", line 6, in <module>
from pycuda.tools import mark_cuda_test, dtype_to_ctype
File "/home/kburdge/anaconda3/lib/python3.6/site-packages/pycuda/tools.py", line 34, in <module>
import pycuda.driver as cuda
File "/home/kburdge/anaconda3/lib/python3.6/site-packages/pycuda/driver.py", line 5, in <module>
from pycuda._driver import * # noqa
ImportError: /home/kburdge/anaconda3/lib/python3.6/site-packages/pycuda/_driver.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEED1Ev
Any pointers on how to resolve this would be immensely appreciated.

Truncated Mean Convolution Kernel
by Rana, Sanjay
Hi Everyone,
I am running a truncated mean convolution but I keep running into cuCtxSynchronize failed type errors when the kernel is called numerous times.
I guess that it's not a timeout issue in GPU issue because it's a compute only GPU.
So, I put it down to memory issues due to the use of list that I need to store in kernel for sorting/truncating values. Am I correct in thinking that the error can be avoided by using shared memory?
Thanks,

Question on PyCUDA, Theano
by Walter White
Hello,
I am struggling running Theano on the GPU.
(WinPython-64bit-3.4.4.1, Theano 0.9.0)
Theano issues the following message:
Message: 'pygpu was configured but could not be imported or is too old
(version 0.6 or higher required)'
Problem is the installation of pygpu / libgpuarray.
http://deeplearning.net/software/libgpuarray/installation.html
I checked and pygpu is not installed.
Is libgpuarray the same as pycuda.gpuarray?
Kind regards,
Joe
