How to save or record detail from llama_print_timings.

I have no idea about to collect these timings of operation. I try to define a variable it always show None or empty.
Thanks.

These are in the stderr output from the underlying llama.cpp library. I did some code a while ago (in node.js) with these. TL;DR you'll likely have grab the strings from stderrand crunch the strings from there.

This solution worked for me. Code snippet below (provide your own file_path):

from io import StringIO

stdout_orig = sys.stdout
stderr_orig = sys.stderr
sys.stdout = StringIO()
sys.stderr = StringIO()

stdout_content = sys.stdout.getvalue()
stderr_content = sys.stderr.getvalue()

sys.stdout = stdout_orig
sys.stderr = stderr_orig

with open(file_path, "a") as file:
file.write("Stderr Output:\n")
file.write(stderr_content + "\n")

After I try to use stderr as you suggest. the result still empty in python. I'm not sure as I do is correct or not.
