ITK Python pyinstaller issue

1

Dear all
I am using ITKPython,
My codes are working well in PyCharm with *.py format but after making a standalone *.exe file via PyInstaller some errors occure as follow:

Traceback (most recent call last):
File “RSG_V_0.py”, line 27, in <module>
File “site-packages\itkExtras.py”, line 449, in imread
File “site-packages\itkLazy.py”, line 40, in getattribute
AttributeError: ‘LazyITKModule’ object has no attribute ‘ImageFileReader’
[29316] Failed to execute script RSG_V_0

Would you please show me the way to solve these kind of problems.
I attaches a simple .py,
By the way, already I test my PyInstaller with a simple print.py.

Hi,

Thank you so much,

You can try to use a hook file with this content:

# This pyinstaller hook file does not support ITK with `WrapITK.pth`.

from PyInstaller.utils.hooks import collect_data_files

hiddenimports = ['new']

# If ITK is pip installed, gets all the files.
itk_datas = collect_data_files('itk', include_py_files=True)
datas = [x for x in itk_datas if '__pycache__' not in x[0]]

Save the code above in a file called hook-itk.py and add --additional-hooks-dir= to the command line calling pyinstaller, with the name of the folder in which you saved hook-itk.py.

If this works for you, I will ask pyinstaller if they can ship this hook file directly in their project.
Thanks!

I created a PR on the pyinstaller project to facilitate using ITK with pyinstaller. I also update my previous answer to improve the hook file that can be used with pyinstaller.

Thanks for the info.

The hook works for me with itk 5.0.1 wrapped in Ubuntu 18 64 bits. I built itk and wrapped it with .pth file.

Saved the hook content in a file “hook-itk.py” in a dir represented by DIR_PATH. Then called:

pyinstaller --additional-hooks-dir=DIR_PATH helloWorld.py

helloWorld.py contains:

import itk

ImageType = itk.Image[itk.UL, 3]
image = ImageType.New()

print(“ITK Hello World!”)
print(image)

print(itk.Version.GetITKVersion())

The generated executable works as intended, its output:

ITK Hello World!
