Error running executable file made using pyinstaller for my python project

Question

I used pyinstaller to make an exe file for my project. When I run the exe file after its done I get the following FileNotFoundError:

Failed to execute script 'main' due to unhandles exception:
[Errno 2] No such file or directory:
'C:\\Users\\p-IN-CHE7-ptsintern\\AppData\\Local\\Temp\\_MEI96922\\ultralytics\\cfg\\default.yaml'

I even tried updating my ultralytics package using pip before making the exe file. Still it returns this error.

It would be appreciated if someone would help me in this matter.

Thank you.

Answer 1

I found a fix for this. So i went to the ultralytics package folder and I had to change a code from __init.py__ under utils (...\ultralytics\utils\__init__.py).

I changed the code on line 35 from:

DEFAULT_CFG_PATH = ROOT / 'cfg/default.yaml'

to

DEFAULT_CFG_PATH = 'Absolute path to cfg/default.yaml'

The cfg/default.yaml is under the ultralytics package folder itself.

I think it might be better to leave the DEFAULT_CFG_PATH empty, but I haven't tried it.
