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](https://github.com/RTKConsortium/RTK/blob/master/examples/FirstReconstruction/FirstCudaReconstruction.py#L13-L14) with the following line:
```Python
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.

Can you explain more about that?
