Hi @AaronVG99 -- sorry for not seeing this report earlier!! do you still have the issue? the code might have changed quite a bit since then.

I have the same problem:

`~$ roslaunch hri_face_detect detect.launch rgb_camera:=usb_cam filtering_frame:=head_camera

process[hri_face_detect-1]: started with pid [19539]

How did you solve it?

[severin-lemaignan]

it looks like the yunet_detector module has not been compiled. How did you install hri_face_detect?

I got the same above problem, how did you solve it. I clone hri_face detect from
https://github.com/ros4hri/hri_face_detect.git
Please help me if you fixed it already

It runs smoothly on my machine.
First make sure to use the correct branch for your system, with ROS Noetic I think the correct one is main or hri_headers while for ROS2 is humble-devel.

i.e. for ROS Noetic you can clone it like this

git clone https://github.com/ros4hri/hri_face_detect.git -b main

The problem with yunet_detector comes from where the python binding installation is.

You can find the location of where your binding is with

find devel -name "yunet_detector.*"

This should return something like:

devel/lib/yunet_detector.cpython-38-x86_64-linux-gnu.so
devel/.private/hri_face_detect/lib/yunet_detector.cpython-38-x86_64-linux-gnu.so

A temporary solution is to move the library to a folder that is actually sourced by source devel/setup.bash with

mv devel/lib/yunet_detector.cpython-38-x86_64-linux-gnu.so devel/lib/python3/dist-packages/

Now you can source the build with

source devel/setup.bash

and the node detect should run
