Tvm_register_object_type

I have a class, inherited from Object:

class WtObj : public Object{} class Wt : public ObjectRef{} and then: TVM_REGISTER_OBJECT_TYPE(WtObj);

in c++: *rv = wt(graph); but when I receive it from python side, i get NoneType: <class ‘NoneType’>, what’s wrong with it ? anybody can help??

I use this like IntVectorObj of tvm_ext,THNAKS!

In python side, I use @tvm.register_object(“tvm_ext.Wt”) class Wt(object): ‘’’’

Would you like to provide a minimum reproducible example?

Thanks! problem resolved!
