pygame.error: Couldn't open tImages/NPC_17.png When running from python3 directly

[John-AZ1]

Hello,

I Just cloned the omnitool directory, and run
python3 run_omnitool.py and everything runs fine until I try to display world, it loads and then the error
pygame.error: Couldn't open tImages/NPC_17.png is spat out. Am I missing resources?

Running python3 on Ubuntu,
I have installed the requirements via pip
