Can't run simple_pose.py

[NabilHunt]

I installed all requirements and I didn't find any mention of the error I'm having elsewhere, when I run python3 simple_pose.py, I get the following error:

Traceback (most recent call last):

I'm not sure what's the problem here, this is being run on a raspberry pi4 with the latest Raspbian. I suspected the issue might be GLIBC version, since mine is Debian GLIBC 2.28-10+rpi1 and I saw in an issue that it must be 2.29 or higher but the error I got doesn't point to that.
