I have the following program that I've been working on (I didn't create all of it, so some of it is pretty weird) on a Raspberry Pi. It's basically supposed to open up a tkinter window with buttons, and if you click the buttons in the right order, a new process will start. If the buttons are clicked in the wrong order, it will play a video. All of this works in Thonny IDE. (Really, the specifics of the program don't matter much other than the fact that it is using omxplayer-wrapper to play videos)

My problem is that I want this to run when the Pi boots up, which involves starting the program from the terminal. If I use "sudo python3 [file path]", it tells me: "Traceback (most recent call last):
File "/home/pi/Documents/alienPasscodeV2.py", line 10, in
from omxplayer.player import OMXPlayer
ImportError: No module named 'omxplayer'".

If I use just "python3 [file path]", it starts off working, until it needs to play a video. Then it tells me:

"Exception in Tkinter callback Traceback (most recent call last):

I have no idea why there's even a difference between using sudo and not using sudo. I've been trying to figure this out for hours and I have no idea. I'm so sorry for this program.

Turns out that when I was setting the paths, I needed to set the full path, not just the name of the file. So the paths changed to /home/pi/Documents/filename.
