问题:

I create a single file python application with Pyinstaller using --onefile parameters. Everything work as expected but the startup time is around 10 seconds on my machine. The problems is that during the file unpacking process of Pyinstaller package there are no visual feedback, so you don't know if the application is starting or even if you really clicked the icon. This problem became worse if the machine is slow (on my test with a very old machine i need almost 20 seconds to see the first login of my application) There is a way to create some splash screen or visual feedback (like a progress bar as on unpackers) during the Pyinstaller bootstrap sequence?

Please note the question is about Pyinstaller unpacking process BEFORE the real application will be executed not by the application itself that already has is own splash screen

thank you

回答1:

One simple solution might be to display the console window after launching the application, which will output the status of the PyInstaller Bootloader while it is being opened.

To display the console, use the --console flag (or edit the .spec file to contain console = True) when bundling your application. These options are documented in the PyInstaller doc file.
