pyinstaller itk failed to execute script due to unhandled exception

Hi all,

I’m trying to write an executable of my python program using PyInstaller. I tried following the below article (using the same test program in said article)

by adding a hook and then writing

python -m PyInstaller --additional-hooks-dir C:\Users\path\hook-itk.py itk-test.py

but it still gives me an error when i try and open the exe file in the dist folder:

RuntimeError: WARNING: Invalid configuration directory requested: C:\Users\path\dist\itk-test\_internal\itk\Configuration
[7808] Failed to execute script 'itk-test' due to unhandled exception!

If it helps, I don’t see an itk folder C:\Users\path\dist\itk-test_internal\itk at all.

^So I tried it again, this time with
python -m PyInstaller --additional-hooks-dir=C:\Users\path itk-test.py

And I got the folder to appear but I still can’t get it to open:

Traceback (most recent call last):

Ok so I found a way to make it work but I don’t know if I broke anything while doing it.

Basically, go to C:\Users\path\dist\itk-test_internal

Then replace all the itk related folders here with the ones in the site-packages folder of the relevant Python install C:\Users.…\Python\Python311\site-packages

And it works! I could always delete the dist folder in case something bad happens so I figured why not play around with it. I’m still not sure why the ones created using PyInstaller don’t have an underscore whereas those in the site packages have one (e.g. ITKPyBasePython vs _ITKPyBasePython) but if it works it works.

Hi, @CrownMella . I recently installed pyinstaller (version: 6.11.1) and pyinstaller-hooks-contrib(version: 2024.10) with python-3.10 on Windows 10. The python script of ITK is just reading an image, gaussian smoothing, and saving the image. And now there is no need to use –additional-hooks-dir. The exe is built successfully. But when I run the exe, there is an error as follows:

FileNotFoundError: [Errno 2] No such file or directory: ‘C:\Users\guo72\AppData\Local\Temp\_MEI302202\itk\support\…\ITKPyBasePython.py’
[PYI-36460:ERROR] Failed to execute script ‘TestITK’ due to unhandled exception!

Can you help me?

I haven’t looked into this in a while so I don’t know what’s been updated but I think you’re missing the itk folder, can you check if it exists? what happens if you try the above with hooks and all? That’s all I can probably give as input.

Yes, you are right. The ITK folder is missing. After added, the problem is solved.
