Install script doesn't complete and gives "Python 3.6 or greater required" error

[andrewrgross]

During installation on a Jetson Nano running Ubuntu 18.4, the install script gave this error. Collectively, a group of us worked around it by editing the install script to remove lines that seemed to cause the problem that weren't relevant to our project.

Here is our edited install file:
