Re: [PyCUDA] ImportError: No module named _driver

hi blahblahblah,
I had same error, and tried your way.
/I did this :/
user@ubuntu:~/pycuda-2011.2.2$ python
Python 2.7.3 (default, Apr 20 2012, 22:39:59)
[GCC 4.6.3] on linux2
>>> import pycuda.driver as cuda
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pycuda/driver.py", line 2, in <module>
from pycuda._driver import *
ImportError: No module named _driver
/But i got error here too: /
user@ubuntu:~$ python
>>> import pycuda.driver as cuda
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File

line 2, in <module>
from pycuda._driver import *
ImportError: libcurand.so.4: wrong ELF class: ELFCLASS32
I am doing something wrong. Can you please elaborate ?

EuroPython anyone?
by Tomasz Rybak
Hello list.
Will any of you attend EuroPython, starting in Florence, Italy
on Monday 2012-07-02?
I'll be there all week and will be glad to meet other PyCUDA users.
Regards.

nvcc not in path
by ggeo
Hello ,
I have done a format and passed Sabayon linux.
When i try to install pycuda (su -c "make install") it shows me the errors:
ctags -R src || true
/usr/bin/python2.7 setup.py install
*** WARNING: nvcc not in path.
.............................
In file included from src/cpp/cuda.cpp:1:0:
src/cpp/cuda.hpp:12:18: fatal error: cuda.h:No such file or directory.
error: command 'x86_64-pc-linux-gnu-g++' failed with exit status 1
make: *** [install] Error 1
My .bashrc file has :
# Put your fun stuff here.
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib:$LD_LIBRARY_PATH
export PATH=~/bin:$PATH
export CUDA_ROOT=/usr/local/cuda/bin
I also added in /etc/ld.so.conf :
/usr/local/cuda/lib64
/usr/local/cuda/lib
The installation of cuda-toolkit4.2.9 was successful.The same with the sdk.
Can someone tell please what can i do now??
Thank you!

scikits.cuda is developed separately from pycuda; it's generally best
to submit problems regarding the former to the scikits.cuda issue
tracker on GitHub unless you believe you have encountered a problem
the involves pycuda.

Problems with GPU arrays
by Andrew Miller
Hello,
While working with PyCuda, I've noticed that several GPU array functions
seem to be giving errors, that should work fine.
*
*
*These are using one-dimensional arrays.*
__imul__ works fine for an array times a scalar, but has errors when an
array is multiplied by another array (this was recently fixed in PyOpenCL)
__pow__ seems to have problems with complex arrays. If I take a complex
array, a, and say a**2, I get an error. This works fine with floats though.
I'm fairly certain that these are just bugs, since both work fine in
PyOpenCL. Is that the case?
Thanks!
