Python in Singularity Container on Ubuntu

[erdemath]

I have ubuntu 20.04 and downloaded singularity 3.10.2. I created a container wherein I need to download, install, run my python codes.
Here is the issue anytime I try to run my container;

[inline]
sudo singularity run ubuntu-python.sif
[/inline]

Output:
