img2pdf for Python 3.9.1 installation error

Question

I am trying to execute a python script that needs img2pdf module.

Note, I already have the Ubuntu package installed for python-img2pdf:

which img2pdf
/usr/bin/img2pdf

Given the following line:

import img2pdf

I get the following:

ModuleNotFoundError: No module named 'img2pdf'

I had only python3.6 version installed before and I have installed python3.9.1 now, After that, I have started getting this error. I think it is something to do with PATH or python default version but after a lot of efforts, I am unable to rectify it.

These are my system details which might help you understand my problem further.

$python -V
Python 3.6.9
$python3 -V
Python 3.9.1
$pip -V
pip 21.0.1 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)
$which python
/usr/bin/python
$which python3
/usr/local/bin/python3
$which pip
/usr/local/bin/pip


Ubuntu 18.04.4
Arm64 arch

Try something like this, I think img2pdf is a shell cmd and cannot be used as a python module ^^

Best regards

import os
img2pdf = os.system("img2pdf /path/to/your/image")
