How To Debug Underlying C++ Library From Python Interface?

I am using apollocaffe and Reinspect. Apollocaffe is in c++ library and Reinspect is in python. Reinspect called apis from apollocaffe. I like to debug those apis inside apollocaff

Solution 1:

If you are interested to debug just the C++ part, you can just start GDB with Python -

gdb python
b <C++ function to break at>
run train.py

Of course you need to compile Caffe with debug information: pass -DDEBUG=1 to cmake options of uncomment the DEBUG = 1 line in your Makefile.config. Debugging both Python and C++ from gdb might be more complicated, see this for example.
