ImfusionSuite python library not imported from anywhere

I am not able to import the imfusion library, I can only import it when the python file is inside the /usr/lib/python3/dist-packages where the imfusion package is.

I have installed the ImfusionSuite through 1 month free trial key, I am on ubuntu 20.04 and I have used 2.44.1 version .deb file for installation. Prior to installing this .deb file I had to install the Qt software development framework 5.12 version, then proceed to install the ImfusionSuite through the .deb file using dpkg.

Does anybody have idea of what I can do ?

This sounds like a PYTHONPATH-related issue.
Have you tried running something like:

export PYTHONPATH=/usr/lib/python3/dist-packages:${PYTHONPATH}

before starting Python?
