Camera not detected if pylon software not installed

[abllnl01]

Describe what you want to implement and what the issue & the steps to reproduce it are:

This repo's Getting Started page says installing pylon is not mandatory. I have noticed on multiple Windows system that pypylon does not detect my Basler camera, e.g. acA4024-29um, if the pylon software is not installed.

Is there a way I can interface with the Basler camera using pypylon without having to install the pylon software?

from pypylon import pylon
try:
    camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
    print("Using device ", camera.GetDeviceInfo().GetModelName())
except Exception as e: 
    print(e)
