I want to study the source code and try to make some breakpoints at both Python code and cpp code by following gdb-integration.
The output is not consistent with the gdb-integration. It seems not to hit the breakpoint. Am I missing something or the tutorial is out of date?
Output:
$ gdb python
GNU gdb (GDB) 11.2

Should I install torch with some special flags?
I installed it with CPU only from source code.
