Omxplayer-wrapper problems when run from terminal

Question

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)

incorrectPath = "Incorrect Password.mp4"
secondVideoPath = "Access Denied.mp4"
secondLoopPath = "loop1.mp4"
GPIO.setup(20, GPIO.OUT, initial=GPIO.HIGH)
GPIO.setup(19, GPIO.OUT, initial=GPIO.HIGH)

GPIO.setup(2, GPIO.IN) #The input for when the power rod is removed (stop 1st looping video)
GPIO.setup(3, GPIO.IN) #The input for when to stop the 2nd looping video

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):
File "/usr/lib/python3.5/tkinter/init.py", line 1562, in call return self.func(*args) File "/home/pi/Documents/alienPasscodeV2.py", line 86, in on_click7 order(IM) File "/home/pi/Documents/alienPasscodeV2.py", line 121, in order incorrectVideo() File "/home/pi/Documents/alienPasscodeV2.py", line 171, in incorrectVideo player = OMXPlayer(incorrectPath, args=["--win", "0 0 1280 1024"], dbus_name='org.mpris.MediaPlayer2.omxplayer0') File "/home/pi/.local/lib/python3.5/site-packages/omxplayer/player.py", line 162, in init self.load(source, pause=pause) File "/home/pi/.local/lib/python3.5/site-packages/omxplayer/player.py", line 245, in load self._load_source(source) File "/home/pi/.local/lib/python3.5/site-packages/omxplayer/player.py", line 171, in _load_source self._connection = self._setup_dbus_connection(self._Connection, self._bus_address_finder) File "/home/pi/.local/lib/python3.5/site-packages/omxplayer/player.py", line 231, in _setup_dbus_connection raise SystemError('DBus cannot connect to the OMXPlayer process') SystemError: DBus cannot connect to the OMXPlayer process"

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.
