Why does Theano print "cc1plus: fatal error: cuda_runtime.h: No such file or directory"?

I am trying to use the GPU with Theano. I've read this tutorial.

However, I can't get theano to use the GPU and I don't know how to continue.

Cuda sample

Compiling and executing worked as a super user (tested with cuda/C/0_Simple/simpleMultiGPU):

When I try this as normal user, I get:

$ ./simpleMultiGPU 
[simpleMultiGPU] starting...

CUDA error at simpleMultiGPU.cu:87 code=38(cudaErrorNoDevice) "cudaGetDeviceCount(&GPU_N)"

How can I get cuda to work with non-super users?

Testing code

The following code is from "Testing Theano with GPU"

#!/usr/bin/env python
from theano import function, config, shared, sandbox
import theano.tensor as T
import numpy
import time

vlen = 10 * 30 * 768  # 10 x #cores x # threads per core
iters = 1000

rng = numpy.random.RandomState(22)
x = shared(numpy.asarray(rng.rand(vlen), config.floatX))
f = function([], T.exp(x))
print f.maker.fgraph.toposort()
t0 = time.time()
for i in xrange(iters):
    r = f()
t1 = time.time()
print 'Looping %d times took' % iters, t1 - t0, 'seconds'
print 'Result is', r
if numpy.any([isinstance(x.op, T.Elemwise) for x in f.maker.fgraph.toposort()]):
    print 'Used the cpu'
else:
    print 'Used the gpu'

The error message

The complete error message is much too long to post it here. A longer version is on http://pastebin.com/eT9vbk7M, but I think the relevant part is:

As some comments told, the problem is the permissio of /dev/nvidia*. As some told this mean during your startup, it don't get initialized correctly. Normally, this is done correctly when the GUI is started. My guess is that you didn't enable it or install it. So you probably have an headless server.

To fix this, just run as root nvidia-smi. This will detect that it isn't started correctly and will fix it. root have the permission to fix things. Normal user don't have the permission to fix this. That is why it work with root (it get automatically fixed), but not as normal user.

This fix need to be done each time the computer boot. To automatise this, you can create as root this file /etc/init.d/nvidia-gpu-config with this content:

#!/bin/sh
#
# nvidia-gpu-config    Start the correct initialization of nvidia GPU driver.
#
# chkconfig: - 90 90
# description:  Init gpu to wanted states

# sudo /sbin/chkconfig --add nvidia-smi
#

case $1 in
'start')
nvidia-smi
;;
esac

Then as root run this command: /sbin/chkconfig --add nvidia-gpu-config.

UPDATE: This work for OS that use the init system SysV. If your system use the init system systemd, I don't know if it work.

Try exporting C_INCLUDE_PATH to cuda toolkit include files on your system, something like:

export C_INCLUDE_PATH=${C_INCLUDE_PATH}:/usr/local/cuda/include
