You are importing the wrong thing. You haven't told us what is in your
YDS.idl file, but it is definitely wrong to import YDS_idl, and you
never import Python code by including the .py extension in the import
statement.

If YDS.idl contains a top-level module declaration like this:

  module YDSModule {
    interface YDSAdminIF {...};
  };

then in Python you need to import YDSModule:

  from YDSModule import YDSAdminIF


If, on the other hand, the IDL file does not contain a top-level
module, like this:

  interface YDSAdminIF {...};

then the Python CORBA mapping says it is in a pretend module called
"_GlobalIDL", so you need to import that:

  from _GlobalIDL import YDSAdminIF
