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 Am I missing something or the tutorial is out of date?
$ gdb python GNU gdb (GDB) 11.2 ... For help, type "help". Type "apropos word" to search for commands related to "word"... Reading symbols from python... (gdb) break at::Tensor::neg Function "at::Tensor::neg" not defined. Make breakpoint pending on future shared library load? (y or [n]) y Breakpoint 1 (at::Tensor::neg) pending.

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