Cannot debug tensorflow using gdb on macOS

Question

I am trying to debug TensorFlow using GDB on macOS Sierra. I followed the instructions on the post .After I installed developer version of tensorflow for debug I tried to use gdb to attach a python session.

When I run gdb -p <pid> :

(gdb)

When I set the breakpoint:

(gdb) break TF_NewSession
Function "TF_NewSession" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (TF_NewSession) pending.

Then even I run sess = tf.Session() as the post says. GDB will never enter into breakpoint.

Answer 1

Well, after I change to use lldb on macOS, everything works fine. So I guess the solution to this problem is "USING LLDB INSTEAD OF GDB".
