Error when running test data

[Amarea1]

I've loaded NextPolish onto a virtual Ubuntu 20.04.2 LTS system and the install seems to have completed without issue, but when I run the test data, I've encountered a traceback error which I'm struggling to resolve. Could you please advise as to what actions I need to take to fix this?

Test data output:

Nextpolish version: command nextPolish -v didn't work but it was downloaded today so I'm pretty sure it's 1.3.1

Hi, the available memory of your system is not enough, maybe you need to try a system with more available memory.
