Not able to run code

[ShaofengZou]

Hi~

Thanks for sharing your work.

but when i run examples.ipynb , i get

AttributeError: /usr/lib/libsvm.so.3: undefined symbol: svm_get_sv_indices

I run it in Ubuntu 16.04 and l have excute the command:

apt-get install libsvm-dev and
pip install --process-dependency-links pybrisque

successfully

Any suggestions would be helpful.

Thanks in advance.

Hi @ShaofengZou, it seems that in Ubuntu 16.04, the libsvm that is distributed is version 3.12 (while the python-binding that we use during the installation of pybrisque is 3.14) and there's breaking changes between them.

You can solve this issue by uninstalling libsvm from pybrisque i.e pip uninstall libsvm and install python-libsvm from distribution i.e apt install python-libsvm (which will have the exact same libsvm 3.12). If you can't import svm, you can try to add /usr/share/pyshared to your PYTHONPATH.

Cheers

Hey, I did that. It seems that the default model type for libsvm might be different in 3.12. On reading allmodel I get, argument 1: <class 'TypeError'>: wrong type, how do I resolve this?

Line: model = libsvm.svm_load_model(model_file_name) in /usr/share/pyshared/svmutil.py
