Knowrob: missing individuals

edit

Dear all,

I correctly installed knowrob and knowrob tutorials. (No warning and errors!) then when I try to execute the tutorial and specifically to query for the individuals of Drawers, I get:

?-register_ros_package(ias_semantic_map). 
true.

And

?- owl_has(A, rdf:type, knowrob:'Drawer').
false.

While I whould get

 ?- owl_has(A, rdf:type, knowrob:'Drawer').
 A = 'http://ias.cs.tum.edu/kb/knowrob.owl#Drawer1' ;
 A = 'http://ias.cs.tum.edu/kb/knowrob.owl#Drawer103' ;
 A = 'http://ias.cs.tum.edu/kb/knowrob.owl#Drawer109' ;
 true.

I installed Knowrob by source as suggested.

Thank you in advance, I think that @moritz can help me.

And when I run:
