Python pyinstaller ModuleNotFoundError even with hidden import

Question

I have 2 files like this. addict is a library, installed by using pip install addict. https://pypi.org/project/addict/

# myimport.py
from addict import Dict

and

# main.py
from pyinstaller_test.myimport import *
print('Hello world')

The folder structure is:

huyduc@my-pc:~/pyinstaller_test$ ls
__init__.py  main.py  myimport.py

I run pyinstaller by using

pyinstaller --hidden-import addict --onefile --name main *.py

I'm not using any venv. What might cause this and how to fix this problem? Thank you.
