Hi all,
on my Linux:
$ lsb_release -a
LSB Version:
:base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description: CentOS release 6.6 (Final)
Release: 6.6
Codename: Final
I have python 2.6.6, numpy-1.4.1-9.el6.x86_64, cuda 6.5.
I tried to install pyCuda following the wiki:
$wget
https://pypi.python.org/packages/source/p/pycuda/pycuda-2014.1.tar.gz#md5=fdc2f59e57ab7256a7e0df0d9d943022
$tar xvf pycuda-2014.1.tar.gz
$cd pycuda-2014.1
$python configure.py --cuda-root=/usr/local/cuda-6.5
$make install
$cd test/
$python test_driver.py
but this gives huge amount of errors like:
# python test_driver.py
