hello all,

I am new in cuda and since I started I am stuck with bunch of problem.after installing scikits and cula I get erroe when I want to run sample test,which is :

Traceback (most recent call last):
File "", line 1, in
ImportError: No module named intergrate

Traceback (most recent call last):

func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /usr/local/cula/lib64/libcula.so: undefined symbol: culaGetStatusString

I am getting this error when I m trying to import this modules :

misc

intergrate

linalg

special

I am using the free edition of CULA DENSE and I should note that I am able to run the c codes cula examples.

I am appreciate any help!

What are the version numbers of the CUDA and CULA packages that you are using?

[llvll0hsen]

CUDA 4.1 and cula R14

Is /usr/local/cula/lib64/libcula.so a link to some other file? CULA R14 shouldn't contain any such file; it might be left over from an installation of an earlier release of CULA.

[llvll0hsen]

yes it doesnt have it so I just make a linker to libcula.core.so because
there where no libcula.so...so what should I do to fix it?

Thanks

I recommend removing the link altogether; most of the functions scikits.cuda loads from CULA are in libcula_lapack.so in R14, not libcula_core.so. If you do need to keep the link for some reason, try installing the latest scikits.cuda code from GitHub; I modified the CULA loader to look for libcula_lapack.so before libcula.so.

[llvll0hsen]

what do you mean by removing all links? you mean libcula_core.so and
libcula_so?

I how should I do the same modification?

today I re-install the scikits.cuda from the GitHub but still have the same
problem! I first remove all directories and files from my dist-packages
folder and then install it again with python setup.py install

am I missing something!?

I meant that you should remove the link libcula.so -> libcula_core.so from the directory /usr/local/cula/lib64/; the directory should contain the following files:

lapackcpu.so
libcublas.so -> libcublas.so.4
libcublas.so.4 -> libcublas.so.4.1.28
libcublas.so.4.1.28
libcudart.so -> libcudart.so.4
libcudart.so.4 -> libcudart.so.4.1.28
libcudart.so.4.1.28
libcula_core.so
libcula_lapack_fortran.so
libcula_lapack_link.so
libcula_lapack_pgfortran.so
libcula_lapack.so
libcula_scalapack.so

[llvll0hsen]

Thanks,ok I did it, but how can I have clean installation of scikits? I
tried to install the development versions from the Github but I m still
have the problem with libcula.so

If you install it as described in the documentation, the relevant files should be updated properly (how did you initially install it?) Note that if you are still observing the undefined symbol error you initially reported, then /usr/local/cula/lib64/libcula.so still exists.

[llvll0hsen]

initially I installed it with pip..but then try to re-install it
from manually. I changed the priority to libcula_lapack.so and now it
works fine. But I was just wondering how should I re-install it again in
case that I need to do it.

Thanks for your help

If you are installing the package manually in the same destination as pip, I don't think it should matter. It's probably best to stick to one installation method in general, though.
