without sudo can not use pytorch

[VincentWPJ]

Version of Singularity:

What version of Singularity are you using? Run:

$ singularity --version
singularity-ce version 3.8.0-rc.1+145-gc85a93c

Expected behavior

What did you expect to see when you do...? I build a image(ubuntu20.04 with gcc9.3.0) in my own machine, and want to run python script with pytorch. everything is good when I use "sudo singularity shell" to start a container, but if I just use "singularity shell" to start it , it can not work.

Actual behavior

What actually happend? Why was it incorrect? when I use "singularity shell" run python script, I will get the error :"ImportError: libtinfo.so.5: cannot open shared object file: No such file or directory"

Steps to reproduce this behavior
