Missing libnvds_msgbroker.so


I am testing objectDetection_Yolo. I have successfully tested it before and I didn’t change any file.

But when I try again later, it says

deepstream-app: error while loading shared libraries: libnvds_msgbroker.so: cannot open shared object file: No such file or directory

I searched online and couldn’t find any result for the file.

Please help

Solved by reinstalling the whole sdk
