How do you debug python parts in your application?

When handling self-written python classes / objects in MATLAB how do you handle debugging?

So far I tried:

• pdb.set_trace at position where I want to start debugging the python parts resulted in errors:

Error using bdb>dispatch_line (line 70)

Python Error: BdbQuit

Error in bdb>trace_dispatch (line 51)

• trying to use outOfProcess execution of python (which might allow attaching an external python debugger) hangs when loading a self-written module, e.g.:

if count(py.sys.path, python_modpath) <= 0

insert(py.sys.path, int32(0), python_modpath);

end

py_mod_planner = py.importlib.import_module(<custom module>);
