How do I use the required packages when converting to exe?

Question

I tried converting a .py file to .exe using auto-py-to-exe, but the packages arent included, and I get this error:

Traceback (most recent call last):
File "imgtoascii.py", line 1, in <module>
ModuleNotFoundError: No module named 'PIL'

How do I use the packages on the file?

--onefile mode, python 3.10
