pyinstaller with customtkinter: exception when running exe --> AttributeError: module 'customtkinter' has no attribute 'CTk'

Question

I have created a Python script, which uses customtkinter for a GUI where the user can select some options.

Here is an overview about the imported packages: used libraries

Everything works properly when I run the script in Pycharm (Community Edition 2021.1.2) and the GUI shows up as expected.

But after building (creating an exe from the script) using pyinstaller and running the exe I get following error message: Error when running exe file

Line 403 makes a problem acc. to this message - the corresponding line in the script looks like: Line 403 causes error

For building the exe I use following command: pyinstaller --noconfirm --onedir --windowed --add-data c:\users\myName\appdata\local\programs\python\python39\lib\site-packages\customtkinter;customtkinter\ DataAnalysisTool.py

Hope somebody can help!

I would expect that the exe file also runs as the script in Pycharm runs without any problem.

Update: minimum reproducible example (throws same error message when running exe)

import customtkinter

# create the root window
root_file = customtkinter.CTk()
root_file.title('Data Analysis Tool - File Selection')
root_file.resizable(False, False)
root_file.geometry('350x150')

root_file.mainloop()

I was able to compile your example code with the following steps:

1. Create a new virtual environment and install customtkinter and pyinstaller

2. create a main.py file with your example code.

import customtkinter

# create the root window
root_file = customtkinter.CTk()
root_file.title('Data Analysis Tool - File Selection')
root_file.resizable(False, False)
root_file.geometry('350x150')

root_file.mainloop()

3. run pyinstaller -F main.py --collect-all customtkinter

The compiled executable runs without error.

It works using the --onedir option as well.
