OSError: libcublas.so.3: cannot open shared object file: no such file or directory

I tried to import cudamat. Then I ran into an error:

OSError: libcublas.so.3: cannot open shared object file: No such file or directory

I tried to find libcublas

/usr/local/MATLAB/MATLAB_Production_Server/R2013a/bin/glnxa64/libcublas.so.5.0
/usr/local/MATLAB/MATLAB_Production_Server/R2013a/bin/glnxa64/libcublas.so.5.0.40

/usr/local/cuda-5.5/targets/x86_64-linux/lib/libcublas_device.a

What can I do? I'm sorry that I am not familiar with ubuntu. Thanks!

QUESTION CLOSED

I decided it myself.

set PATH and LD_LIBRARY_PATH first

$ export PATH=/usr/local/cuda-5.5/bin:$PATH
$ export LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:$LD_LIBRARY_PATH

Then create a symlink

sudo ln -s /usr/local/cuda-5.5/lib64/libcublas.so /usr/local/cuda-5.5/lib64/libcublas.so.3

In a slightly different situation, the same warning may be caused by a literally missing lib file, i.e. the files are .libnot in $CUDA/lib64/. For example, the following code did not show libcublas.soin this directory.

sudo find / -iname libcublas*
/usr/local/cuda-7.5/doc/man/man7/libcublas.so.7
/usr/local/cuda-7.5/doc/man/man7/libcublas.7
/usr/local/cuda-7.5/targets/x86_64-linux/lib/libcublas.so.7.5
/usr/local/cuda-7.5/targets/x86_64-linux/lib/libcublas_static.a
/usr/local/cuda-7.5/targets/x86_64-linux/lib/stubs/libcublas.so
/usr/local/cuda-7.5/targets/x86_64-linux/lib/libcublas_device.a
/usr/local/cuda-7.5/targets/x86_64-linux/lib/libcublas.so.7.5.18
/usr/local/cuda-7.5/targets/x86_64-linux/lib/libcublas.so

, : $CUDA/lib64/ lib $CUDA/targets/x86_64-linux/lib. :

sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/* $LD_LIBRARY_PATH
-1
