setup.py.in installation failure, Windows 10, VS 2019, CMAKE 3.17.2

[olalla1999]

Hello! I tried to configure SimpleElastix on windows 10, 64 Bits, VS 2019, cmake 3.17.2, python is Anaconda. While configuring in CMAKE some warnings appeared, then I "unclicked" some of the options leaving WRAP_PYTHON, BUILD_EXAMPLES and BUILD_TESTING activated. Then I pressed "Advanced" and I configurated again. Then I pressed "Generate".

After that, I went to the "Build" folder created and doble clicked on "SuperBuildSimpleITK.sln". Inside VS2019 I went to Build>Configuration Manager and activated the SimpleITK-build option (leaving the default activated options the same). Then, I built ALL_BUILD and waited for 45-50'. This were the last lines of the Command Window:

I didn't know what those errors meant but as I saw this folder was created inside "Build" folder, I thought it was all right.

C:\KK\Build\SimpleITK-build\Wrapping\Python\Packaging Inside here the IN file setup.py.in.

In order to install this file in Windows, I typed "python setup.py install" in the Command Prompt of Windows. To check if it worked, I went to Spyder app and wrote:

import SimpleITK as itk itk.E...

but no Elastix attribute was found for the SimpleITK library.

Can anyone help me?

Thanks in advance!

Can you build the "dist" target? This will build a wheel for you which may be easier to install.

It's hard to see what goes wrong from the command line (but thanks for the detailed description). You can try out the "azure-simpleitk-ci" branch which worked for me with VS 2019 just yesterday.

Thank you for answering! but I finally solved it by reinstalling Anaconda3 and activating the option of "Add it to your PATH" (although the it's not recommended by Anaconda installer) that appears while you are installing it. Also I installed Git from https://git-scm.com/download/win .

Also, to configure and generate all the files, I used the Anaconda Prompt instead of the Windows prompt. [Important to activate WRAP_PYTHON and check that the paths of PYTHON_EXECUTABLE, PYTHON_INCLUDE_DIR and PYTHON_LIBRARY are related to anaconda's directory].

Then, I opened VS 2019 --> opened the Developer Command Prompt, went to the build folder directory and compiled everything from there: msbuild ALL_BUILD.vcxproj /p:Configuration=Release. Two and a half hours later (10 warnings 0 errors), I copied the file _SimpleITK.pyd that was created in the folder C:\KK\build\SimpleITK-build\Wrapping\Python and pasted it into the folder C:\KK\build\SimpleITK-build\Wrapping\Python\Packaging. This folder should look like this:

Finally, I opened VS Code from Anaconda and typed python setup.py install. That was it!

I hope this helped Windows users!

PS: watch out the 'System enviornment variables' of Windows to have all the paths including cmake, visual studio, anaconda and Git.

Great job! And thanks for documenting your experience for future users. I will update the documentation.

This last part of olalla1999's comment seems to work. I managed to finally build and install as well... Please be sure to uninstall older versions of SimpleITK (installed through pip for example) before installation. I used the command line method and then moved the files as mentioned above and ran the installation in the proper env. I spend a few days getting this to work, over the past three months.

My takeaways: 1) cmake, anaconda and Git should be in the environment PATH variable (be sure to check this in native windows 'cmd' application by typing PATH). 2) follow the instruction at https://simpleelastix.readthedocs.io/GettingStarted.html#using-the-command-line for windows. 3) after running cmake ../SimpleElastix/SuperBuild, turn all Wrapper Booleans to OFF (in the file: build/CMakeCache), except for Python wrapper, and then run msbuild /p:configuration=release ALL_BUILD.vcxproj 4) move the files as described above, open your env and run python setup.py install. 5) Check once again if you have multiple versions of SimpleITK, if you do, please delete the one (in my case it vas v2.0.2 that was already installed through pip). The current installation through the method above yields v2.0.0)
