I have built ./build_gaps.sh successfully.
And /gaps_is_installed.sh print out Ready to go!
But I still get this Bus error "/process_mesh_local.sh: line 47: 13856 Bus error (core dumped) ${gaps}/msh2msh $mesh_in $mesh -scale_by_pca -translate_by_centroid -scale 0.25 -debug_matrix ${outdir}/orig_to_gaps.txt"
when runing

python meshes2dataset.py --mesh_directory [path/to/dataset_root]
--dataset_directory [path/to/nonexistent_output_directory]

Anyone knows why?
