Change the python version to higher or lower it worked for me.https://lists.gt.net/python/bugs/1299839

thanks @yeswanthkaali , I had this python issue in my knowledge as i was trying to troubleshoot, but I was running on macos with python 3.7 it was throwing bad file descriptor error while accessing queue.

so for workaround i used normal Queue instead of python MP queue but with thread not as multiporcess because normal queue cant be shared between process

But in ubuntu with python37 it is running fine.
