I use pyinstaller to generate a demo that can reconstruction data and show the result. The reconstruction is similar to FirstCudaReconstruction.py. My list of installed package is below.

I use pyinstaller XX.spec to generate .exe file. The folder didn’t contain itk first, and I append hiddenimports=['itk'] on the .spec file.
The demo can run correctly on my computer, but an error occurred on other computers when the code runs to

itk.RTK.CudaImage[itk.F, 3]

I think may I didn’t correct pyinstaller itk, but I don’t know how to solve it. Any help would be appreciated.

I don’t know pyinstaller but it seems related to inability to locate Cuda DLLs, which is solved in the example with the following line:

os.add_dll_directory(os.path.join(os.environ['CUDA_PATH'], 'bin'))

I print the path of Cuda when the demo run in other computer. It seems related to inability to locate Cuda DLLs.

Should the DLL used in code itk.RTK.CudaImage[itk.F, 3] not be _ITKCommonPython instead of _CudaCommonPython?

I copyed all the files about itk from site-packages, and replace the files on the exe folder.
Before this operation, I also made the following attempts：

  1. Pip uninstall itk and reinstall itk;
  2. Add itk’s path to .spec;
  3. Try pyinstaller from begin;

There was no error reported in the end.

Hi,

This post is helpful for the pyinstaller + ITK + RTK process:

Thank you for your reply. I have try this method on the fist, but it didn’t work.

But when I try the three attempts and then use that method again. It works. I don’t know why, but at least the result is good.
