Pyinstaller exe shows blank screen

[Aftab Sarwar]

I have a Kivy app that works fine from Pycharm IDE or when run from command line. However, after converting it to an exe with PyInstaller, the app only shows a blank screen and stays there. I'm using Python 3.12, Kivy 2.3 and Pyinstaller 6.6.0. 

Note: The app/window does not close itself, it just stays there but I cannot see any widget on it.

I have tried to downgrade the Pyinstaller to 6.0.0 and 4.0.0 with no success.

I have also tried to downgrade Kivy to 2.0.0 with no success.

I see no message on console after "Start application main loop".

Please help as I have already spent much time on it.

Share your pyinstaller spec file.

My guess is that the program can not find the kv files.  DId you add them to the datas section?

There is a kivy logfile located at:  "C:\Users\your_username\.kivy\logs", read the log file for clues to the issue.

Here is a working spec file - you may find this helpful.  This project has a dir structure that complicates things a little.

https://github.com/ElliotGarbus/KivyCythonWinSample/blob/main/inno-pyinstaller/w11-app.spec

In the most recent version of pyinstaller there was a change to the content directory location, either use full file path addressing or set the contents directory to '.'

See the exe section:

contents_directory='.',

read: https://pyinstaller.org/en/stable/runtime-information.html#using-file

If you sent the contents directory to '.', you do not need to use __file__, the launcher will set the current working directory.  If you do not change the content_directory, you must reference files relative to __file__.

Actually I do not add any files to the exe, I simple run the pyinstaller -F program.py

Then place all the files in the dist directory. This has worked for me for very long. I make sure that all the kv files are there in the dist directory. 

Here is my data from the log file:

The location of files relative to the exe changed in PyInstaller 6.0

You could try going back to version 5 and see if that makes  a difference.

WIth kivy I have always used one-directory builds with a specfile.  I then use innosetup to build a Windows Installer.

What is the new relative path in Pyinstaller 6.x.x? Could you please tell me?

[Aftab Sarwar]

You are right, this issue is about the relative path to the kv files. I added exception to a few files and it showed error for another file (previous ones were not shown in error message). Either I need to change the relative path or use your method of using spec file. thanks for the help, I'll update with the result of my changes.

Thanks a lot.

[elli...@cox.net]

According to the docs, this change only impacted one-directory builds.  In version 5 and prior the exe and all the files were located in the same directory.  In version 6 in a one-directory build all the files are placed in sub-directory from where the .exe is located.

I'm surprised you are able to build a one-file build with kivy, by copying the kv files post build.  When pyinstaller is creating the exe it is zipping all of the files.   You may want to use --add -data to the command line,  https://pyinstaller.org/en/stable/usage.html#cmdoption-add-data

or move to using a specfile.
