problem while running estimate_gaze.launch

[qgy1384]

The ros version I used is noetic and the dlib version is 19.14,and the following error occurs when I running the launch file. (This error occurs when a face is detected)Coulid you please tell me the reason and how to corret it, thank you.

Has dlib changed their function arguments for compute_face_descriptor()? It seems we might not be compatible with 19.14. Try downgrading, from my memory, 19.11 worked but that could well be incorrect.

Alternatively, try switching off the face tracker module if you're only tracking one person and there isn't a requirement for re-identification.

@qgy1384 - how did you solve this?
