This folder usually only contains 'hier_blocks'. Executable flowgraph
pythons files are usually created in the same folder your .grc file is
located in.

Did you replace a class by [Class]? According to the Tutorial it
expects an object of type gr.top_block in this line.

it would run to attach GDB. However, i am getting the following error:

You try to call run on a 'hier_block'. 'run' is a member of
'gr.top_block'. top_block contains the scheduler and takes care of
correct initialization etc. So it is essentially the flowgraph.

I hope I could give you some hints on what might go wrong.
