Hi I have installed codeProject.ai server for linux and run. It is running in my device as expected. But When I try install module which is YOLO v5.3.1 , It throws the below error :

How should i overcome this issue ?

What I have tried:

I have reinstalled the codeProject.ai and tried to install module again ( YOLO v8 )It got installed again as below:
