Global PakedFunc arith.intset_single_point is already registered

I am writing applications on x86 linux with tvm as the compiler. The compilation and linking have passed successfully. But when I run the application, it throws an instance of dmlc::Error “registry.cc: Check failed: override: Global PackedFunc arith.intset_single_point is already registered” Then I launched gdb to trace the app, and I got the location function “PyImport_ImportModule()” which resulted to the error. But I have no idea why the python interface confilicts with the tvm. Any friends have encountered this problem before? Thanks.

@merrymercy, would you please help me check this problem? Thank you
