First, please keep the list cc'd. That makes answers searchable.
Second, could you try upgrading that? You don't even need to mess with
your system to do so--just use a virtualenv.

It is. What's your version of numpy?

Install issue
by Mike McFarlane
Hi
I've installed pycuda following
http://wiki.tiker.net/PyCuda/Installation/Linux
When I try to run test/test_driver.py it fails many tests, mainly with
'TypeError: 'numpy.ndarray' does not have the buffer interface'. The output
is below for test_driver.py and the initial make.
Can anyone explain what is wrong please?
Thanks, and apologies if this mailing list isn't the right place for such
Qs.

I try to catch vandalism of this nature and undo it right away,
but this seems to have slipped through the cracks. Sorry about that, it
should be back up.

Windows installation instructions have been deleted from the wiki

The instructions to build and install PyCUDA on Windows have been removed
from the wiki. There was a very detailed set of instructions that I had
previously used to successfully install. Can these still be found
somewhere? Is there a way to restore them to the wiki?

Thanks Andreas, this is good to know. I noticed that even though pycuda
is currently only using one of two GPUs, that GPU is only ever at ~35%
memory and ~22% processing utilization. This could be related to Eric's
observation that the PCI-e 16x bus bandwidth reaches capacity while the
GPU is pushing out fast FFT'ed arrays. Thus allowing for only one or two
arrays in the GPU at the same time.
From what I have seen, using cuda speeds up my FFTs ~2x. Though, the
workers do many other computations on the CPU. It's a worst case
scenario that all N workers are trying to send data to the GPU at the
same time.

It depends on how Ubuntu builds PyCUDA.
Check pycuda package dependencies:
$ apt-cache show python-pycuda
whether there is any dependency on package
with 5.5 in its name, or only 6.0 packages.

Question How to Safely Use pycuda with mpi4py
by kjs
Hello,
I have written an MPI routine in Python that sends jobs to N worker
processes. The root process handles file IO and the workers do
computation. In the worker processes calls are made to the cuda enabled
GPU to do FFTs.
Is it safe to have N processes potentially making calls to the same GPU
at the same time? I have not made any amendments to the cuda code[0],
and have little knowledge of what could possibly go wrong.
Thanks much,
Kevin

Check if 'dmesg' reveals anything. You might have a mismatch between
libcuda.so and you driver. (If so, good job, Ubuntu.)

Problem with PyCUDA on Ubuntu 14.10
by Eric Larson
PyCUDA worked perfectly on Ubuntu 14.04, but after upgrade to 14.10 I get
the following in both Python 2 and Python 3:
>>> import pycuda.autoinit
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/home/larsoner/.local/lib/python2.7/site-packages/pycuda-2014.1-py2.7-linux-x86_64.egg/pycuda/autoinit.py",

cuda.init()
pycuda._driver.Error: cuInit failed: unknown
This is the same on latest `master` (shown above) and using the version in
the Ubuntu repos. I can manually compile and run at least this example
(devicequery):
http://www.cac.cornell.edu/vw/gpu/example_submit.aspx
and my system is using the proprietary NVIDIA drivers, so CUDA appears to
be configured properly. Has anyone else experienced this? I've reported the
bug here as well:
