Error when reading potentials

[Khue Le]

Hello,

I tried to read data from OpenGM graphical models but got some assertion error. The code below reads the Tsukuba stereo model and displays the potentials of the first edge factor:

    GM gm;

    opengm::hdf5::load(gm, "mrf-stereo/tsu-gm.h5","gm");

    int V = gm.numberOfVariables();

    int L = gm.numberOfLabels(0);

    // Check the first pairwise potentials

    GM::FunctionIdentifier fid = gm[V].functionIndex();

    //TruncatedAbsoluteDifferenceFunction<double> f = gm.getFunction<TruncatedAbsoluteDifferenceFunction<double> >(fid);

    ExplicitFunction<double> f = gm.getFunction<ExplicitFunction<double> >(fid);

    for(int li = 0; li < L; li++){

        for(int lj = 0; lj < L; lj++){

            cout<<"li = "<<li<<", lj = "<<lj<<", f(li,lj) = "<<f(li,lj)<<endl;

        }

    }

Could you please tell me what I'm doing wrong?

Thank you in advance.
