ImportError: libvigraimpex.so.11: No such file or directory in running demo.sh

[helxsz]

I am running demo.sh, and I met such a problem.

File "src/test.py", line 32, in
import utils as utl
File "/home/sizhexi/caffe/ccnn/src/utils.py", line 3, in
import vigra
File "/usr/lib/python2.7/dist-packages/vigra/init.py", line 113, in
import vigra.vigranumpycore as vigranumpycore
ImportError: libvigraimpex.so.11: cannot open shared object file: No such file or directory
Time in seconds: 1

I have installed latest vigra from github, this is the libs

ubuntu:/usr/lib/python2.7/dist-packages/vigra$ ls
analysis.so filters.so impex.so optimization.so ufunc.py
arraytypes.py geometry.so init.py pyqt utilities.so
blockwise.so graphs.so learning.so sampling.so version.py
colors.so histogram.so noise.so tagged_array.py vigranumpycore.so

I didn't find the libvigraimpex library, what goes wrong

It seems that vigra is an ignored dependency of ccnn, if you build vigra from source, you should add the path of libvigra*.so to LD_LIBRARY_PATH
