Notes:

• LLDB can only debug the C++ portion of your code if it's compiled in Debug mode and if you are running a python process that is referencing your C++ code.
• It's important to do continue after attaching to the python pid because lldb is pausing the process until you do

1. Set a breakpoint at the beginning of your python code with pdb or similar

import pdb
pdb.set_trace()
