as the image shows.I start 3D Slicer with debug mode using VS2013, but I can’t a module named ‘Editor’ which exists in 3D Slicer installation version.  
I tried several version in Github and none of them has Editor module.What problem is it?

Thanks for sending the screenshot - in the terminal where you started Slicer there’s a python error saying that numpy cannot be imported and that’s why the Editor didn’t load.

You’ll need to go back and debug the build process to make numpy work since a lot of Slicer code depends on it. Building numpy, especially on windows, can be tricky, but if you describe your steps and post build logs hopefully someone here can help.

Also, for developers who build Slicer, it is recommended to use the latest master version (now 4.9) but at the very minimum the latest stable (now 4.8).

thanks for replying!  
indeed I didn’t build numpy,because it makes building unsuccessful.  
can you tell me where to find build logs?

On Windows the build logs are in [SuperbuildDir]\x64[Configuration] for example S4R\x64\Release

when use CMake to generate the project, make sure the ‘Slicer\_USE\_NUMPY’ is selected.

the later compile in VS2013 maybe fail many times.I just compile over and over until it succeed…😂

If you need multiple attempts for the build succeed then most likely something interferes with the build process. It might be a too aggressive firewall disrupting network communication, antivirus software preventing/delaying file access, etc.

maybe you are right, I didn’t close the firewall.😬
