Hi,

I’m building InsightToolkit-5.1.0 on Ubuntu 20.04 with BUILD\_EXAMPLES ON and ITK\_WRAP\_PYTHON ON. Two questions.

1. 

The make command succeeded. The make install command generated an errror:  
Make Error at Modules/Remote/SphinxExamples/src/Core/Common/ImportPixelBufferIntoAnImage/cmake\_install.cmake:57 (file):  
file INSTALL cannot find  
“/data/pkg/InsightToolkit-5.1.0/Modules/Remote/SphinxExamples/src/Core/Common/ImportPixelBufferIntoAnImage/Code.py”:

I see that ImportPixelBufferIntoAnImage/CMakeLists.txt tries to install that file:  
install(FILES Code.cxx CMakeLists.txt Code.py  
DESTINATION share/ITKExamples/Code/Core/Common/ImportPixelBufferIntoAnImage/  
COMPONENT Code  
)

Should I try to get that file or take it out of the CMakeLists install list ?  
I see my Example tar file does not have the Code.py file:

> tar -vtf InsightSphinxExamples-5.1.0.tar | grep ImportPixelBufferIntoAnImage  
> drwxrwxr-x root/root 0 2020-06-02 12:41 InsightSphinxExamples-5.1.0/src/Core/Common/ImportPixelBufferIntoAnImage/  
> -rw-rw-r-- root/root 746 2020-06-02 12:41 InsightSphinxExamples-5.1.0/src/Core/Common/ImportPixelBufferIntoAnImage/CMakeLists.txt  
> -rw-rw-r-- root/root 4960 2020-06-02 12:41 InsightSphinxExamples-5.1.0/src/Core/Common/ImportPixelBufferIntoAnImage/Code.cxx  
> -rw-rw-r-- root/root 1007 2020-06-02 12:41 InsightSphinxExamples-5.1.0/src/Core/Common/ImportPixelBufferIntoAnImage/Documentation.rst  
> -rw-rw-r-- root/root 128 2020-06-02 12:41 InsightSphinxExamples-5.1.0/src/Core/Common/ImportPixelBufferIntoAnImage/OutputBaseline.png.sha512

1. 

Does ITK python wrapping support Python2 ?  
I set my  
PYTHON\_EXECUTABLE to a Python2 executable, but I see these  
Python3 settings came up in ccmake:  
Python3\_LIBRARY\_DEBUG:FILEPATH=  
Python3\_LIBRARY\_RELEASE:FILEPATH=/usr/lib/x86\_64-linux-gnu/libpython3.8.so  
\_Python3\_INCLUDE\_DIR:PATH=/usr/include/python3.8  
\_Python3\_LIBRARY\_RELEASE:FILEPATH=/usr/lib/x86\_64-linux-gnu/libpython3.8.so

thanks  
Kate

I am not surprised that ImportPixelBufferIntoAnImage/Code.py does not exist, as that example demonstrates a lower-level feature. Code.py should be removed from `install(FILES` list. It is probably a copy-paste from another example (which contained Python version) that was not cleaned up 100%.

Thanks very much, removing Code.py from install(FILES list in CMakeLists.txt worked. I can now make and make install.  
Note I also had to remove Code.py in the ConvertArrayToImage folder, and, I had to change Create3DVolume.cxx, ReadMesh.cxx to Code.cxx in the InsightToolkit-5.1.0/Modules/Remote/SphinxExamples/src/Filtering/ImageGrid/Create3DVolume and src/IO/Mesh/ReadMesh folders.

That sounds like a good cleanup. Can you [submit](https://github.com/InsightSoftwareConsortium/ITK/blob/master/CONTRIBUTING.md) your changes as a patch?
