It turns out that the class ast.Str is removed from the standard library starting from Python 3.12. It requires an update on the tool dependencies. I'm working on it and will update this thread once it's complete
The fix has been pushed out. Please update to version 0.3.2 and try again, thanks
The original fault is gone but I have a new fault now.

AttributeError: 'NoneType' object has no attribute 'is_folder'
I tried to build the customtkinter package.
Could you provide a sample package that reproduces the error when merak tries to build the binary?
yes, I could. it's in my previous comment, last line. here it is again: I tried to build the customtkinter package.
It appears that the absolufy_import library fails in a couple of legitimate use cases, and rope might not have taken care of the module moves properly. It ended up requiring a full refactoring of the code base to get rid of both libraries. The package restructuring logic is done, what's left is the wire-ups
The issue is fixed. Please upgrade to 0.3.3.1 and try again. Please note that Customtkinder's binary built by merak will not work properly due to the nature of module flattening as the project has code that tries to determine the package root via a chain of os.path.dirname to __file__ in modules not directly under the package root
There are multiple .py files which indeed want to load other files (.ttf, .json, .ico) from the python package.
These use os.path.dirname, os.path.abspath and os.path.join functions.
But all of these considered under the package root and not somewhere else. They all wants to load a file from the assets package subfolder.
So would it help to rewrite the code and eliminate those functions or not?
Instead of script_directory = os.path.dirname(os.path.abspath(__file__)) we could use
import importlib.util
spec = importlib.util.find_spec(package)
script_directory = spec.submodule_search_locations[0]
Which would give us the package root absolute path:
>>> import importlib.util
>>> spec = importlib.util.find_spec("customtkinter")
>>> spec.submodule_search_locations[0]
'...\\Lib\\site-packages\\customtkinter'
And instead of
customtkinter_path = pathlib.Path(script_directory).parent.parent.parent
with open(os.path.join(customtkinter_path, "assets", "themes", f"{theme_name_or_path}.json"), "r") as f:
we could do string concatenation (use the script_directory above):
customtkinter_path = script_directory
with open("%s/%s/%s/%s.json" % (customtkinter_path, "assets", "themes", theme_name_or_path), "r") as f:
What do you think?

merakwill not work properly due to the nature of module flattening as the project has code that tries to determine the package root via a chain ofos.path.dirnameto__file__in modules not directly under the package root
I cannot even test it because it still drops an error right away after import and this error does not seem to have anything to do with the __file__ in modules:
>>> import customtkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "customtkinter\\__init__.py", line 95, in init customtkinter
ModuleNotFoundError: No module named 'windows'
Thanks for reporting. I've patched the tool, please upgrade to v0.3.3.2 and try again
Regarding the package path, one can also define a module just under the main package and extract package location from there. Say, the module is defined in customtkinter/datalib.py and inside, one can write
import pathlib
PACKAGE_ROOT = pathlib.Path(__file__).resolve().parent
and use PACKAGE_ROOT to navigate to your expected package data location. For instance:
from customtkinter import datalib
theme_path = datalib.PACKAGE_ROOT.joinpath("assets", "themes", "blue.json")
Thanks for reporting. I've patched the tool, please upgrade to v0.3.3.2 and try again
yes, it is better. Now it complains about those files to be imported from the package which we discussed it won't work properly and the related __file__ error: NameError: name '__file__' is not defined
This is ok for now, I need to raise an issue with customtkinter and see if the owner would change the code....

I have tested this but it does not work.
I just raised an issue on customtkinter #2614 where you can see a code change a proposed.
But now when I just tested it with merak, the pyd import still fails....
It seems it does not like __file__ at all so pathlib.Path(__file__) does not work either.

I will need to update my customtkinter issue once we sorted out this problem.
This seems to be related to CYTHON_PEP489_MULTI_PHASE_INIT=0 option. I'll take a look
I've tried removing the flag and this is what I see. It appears that I've passed the "customtkinter\\___windows_widgets_theme.py", line 4 mark and the error comes from line 9 & 11, so I guess this flag can be omitted without issues. I've also tried building rsa and it works fine as well. Please try it in v0.3.3.3

If packaging with pyinstaller was used, have a look at the wiki:
https://github.com/TomSchimansky/CustomTkinter/wiki/Packaging#windows-pyinstaller-auto-py-to-exe
You have those errors because the assets folder is not under the expected path.... which is okay based on the current code which uses os.path...
If you copy the assets subfolder under /Users/davidmuk/workspace then these errors should disappear.
For me this part works. I don't have those errors after copying assets folder where the python code expects.
I have a new error but it's not a problem to you, it is a minor fault in customtkinter:

add is considered either string or bool which is not entirely correct here...

But.... when I try to use the pyd file, it fails unfortunately...

According to the customtkinter website Windows, Linux and MacOS are supported:
CustomTkinter is a python UI-library based on Tkinter, which provides new, modern and fully customizable widgets. They are created and used like normal Tkinter widgets and can also be used in combination with normal Tkinter elements. The widgets and the window colors either adapt to the system appearance or the manually set mode ('light', 'dark'), and all CustomTkinter widgets and windows support HighDPI scaling (Windows, macOS). With CustomTkinter you'll get a consistent and modern look across all desktop platforms (Windows, macOS, Linux).
I have never seen Segmentation fault with customtkinter before.
I use Windows 11 by the way.
I've also inspected the file
customtkinter/windows/__init__.pyand I don't see any import for thewidgetsubpackage. I don't quite understanding how this is working for others
I think the problem is within the ctk_base_class.py.
If you have a look of this: def _detect_color_of_master()
You can see it has the following if-else condition:
if isinstance(master_widget, (windows.widgets.core_widget_classes.CTkBaseClass, windows.CTk, windows.CTkToplevel, windows.widgets.ctk_scrollable_frame.CTkScrollableFrame)):
if master_widget.cget("fg_color") is not None and master_widget.cget("fg_color") != "transparent":
return master_widget.cget("fg_color")
elif isinstance(master_widget, windows.widgets.ctk_scrollable_frame.CTkScrollableFrame):
return self._detect_color_of_master(master_widget.master.master.master)
I guess the windows.widgets or windows.* parts could cause the problem we have....
AttributeError: module 'customtkinter.___windows' has no attribute 'widgets'
UPDATE: have a look of the imports in the beginning of that file... Not sure if this conflicting with your scripts...
from .... import windows # import windows for isinstance checks
I guess the windows.widgets or windows.* parts could cause the problem we have....
AttributeError: module 'customtkinter.___windows' has no attribute 'widgets'
Yes, the issue we hit is that windows does have a subpackage named widgets, but it is not imported in customtkinter/windows/__init__.py. Therefore the interpreter is not able to find that name/identifier in windows. That looks reasonable to me. That's why I wanted to try out the library to see how it is able to refer to windows.widgets despite widgets is not imported under windows's init file, but I've got segmentation fault, no matter how I imported the library (I'm on Mac)
UPDATE: have a look of the imports in the beginning of that file... Not sure if this conflicting with your scripts...
from .... import windows # import windows for isinstance checks
I don't see any conflicts here. All Merak does is to transform it to absolute import (from customtkinter import windows) and perform module renaming windows -> ___windows
If you have another look at the package structure, you can see that every folder (subfolder) has a __init__.py included.
So this means to me that if you import windows with
from .... import windows # import windows for isinstance checks
and after that you refer to anything under it like windows.widgets.xxx then it will work since widgets folder has it's own __init__.py.
This means you don't need to import widgets per se, as you expect.
Basically, every folder is a (sub)package...
Does this make sense to you?
There seems to be some misunderstanding on how the import system works. Please refer to the documentation on how it works
Basically, when an import-from statement is executed, the interpreter loads all the packages along the module path, and binds a name defined by that statement to the module itself.
from a.b.c import d
# Loads "a" -> "a.b" -> "a.b.c" -> "a.b.c.d"
# Binds the name "d" to the module/package/attribute "a.b.c.d"
The names of a package that one can access through "." is defined in its __init__.py file. If such name is not defined in it, even though b is a subpackage of a, b is still not accessible via . from the name a, despite it is loaded in the memory
5.2.1. Regular packages¶
Python defines two types of packages, regular packages and namespace packages. Regular packages are traditional packages as they existed in Python 3.2 and earlier. A regular package is typically implemented as a directory containing an init.py file. When a regular package is imported, this init.py file is implicitly executed, and the objects it defines are bound to names in the package’s namespace. The init.py file can contain the same Python code that any other module can contain, and Python will add some additional attributes to the module when it is imported.
I am a simple user and not the developer of customtkinter. 😄
The original package works, I use it for my application. So I assume the code is fine. Yes, perhaps I might misunderstand some logic of python overall but I was just simply trying to help you to fix the issue.
Unfortunately, I cannot really troubleshoot your tool hence, I don't know why that error occurs with the binary package. But to me it seems it's related to package import and when it's interpreted in your code.
If you add more debug to your code, I can compile it again with -vv and then share the logs, if that helps.
There might be a possibility that the import system implicitly added names to the package itself. This requires further experiments to verify its behavior.
I'm not sure how it's working for you as I'm seeing segmentation fault when trying to import customtkinter, so the expected behavior of this library is not observable from my side. I'll need a working copy of it before I'm able to understand what has been happening underneath
