View the dependency path of the compiled program:

build$ chrpath -l demo 
demo: RPATH=/mnt/hgfs/vmsharefolders/libtorch/lib:/home/wmz/Desktop/mypractice/pytorch-demo/../libs

Modify the dependent library path:

build$ chrpath -r ../../libs demo 
demo: RPATH=../../libs
demo: new RPATH: ../../libs

Note that the middle line is the old path, and the last line is the new path. Originally, these two lines should be different, because I have executed it again before, and I will execute it again here just for notes.

Final advice: generally don't use this tool, otherwise you don't know how to solve the problem.
