i have some issue (im not good at ai/ml stuffs) , so as per my case im using an ubuntu 20 server with 16 gigs of ram and activated the virtual environment manually and all the packages are install properly though i think something is messed :)

Unfortunately I am also not experienced in AI stuff. I was only able to get it installed properly. I didn't use this script since I created it. But it seems that the human pose estimation got an update and the parameter demo is no longer used as you can see here: https://github.com/Daniil-Osokin/lightweight-human-pose-estimation.pytorch/blob/1590929b601535def07ead5522f05e5096c1b6ac/modules/keypoints.py#L64
It was changed already 3 years ago in this commit: Daniil-Osokin/lightweight-human-pose-estimation.pytorch@ee9e4cc

So if you are lucky you can just delete the demo=True parameter in getrect.py on line 30 and try again.
