merlin's Issues

Segfault when running the CTE algo for marginals

I'm getting a segfault when running the CTE algorithm for computing marginals.

This is how I'm invoking merlin:

merlin --input-file 01-example-paskin.uai --task MAR --algorithm cte --output-file 01-example-paskin.uai

This is the log:

I implemented this example based on the MRF below which was taken from here.

Would you know if I made an error defining this MRF? Or could it be that there is a bug in the software?
