DeepInfer and probably some other modules do not work in Slicer 4.11 due to python 3 incompatibility. [1]
I have made some changes to the code to make it compatible with python 3 but the problem is that it would not work in the previous Slicer versions including 4.10.
Is there any way to specify a specific git id in the s4ext file for Slicer v <=4.10 to support backward compatibility and master for v>=4.11?
The factory build machines are no longer building Slicer 4.10 extensions so updates to https://github.com/Slicer/ExtensionsIndex/tree/4.10 won’t result in any changes. The current stable is the Slicer 4.11.20200930 snapshot. Updates for this new stable for the factory to build would be made to the s4ext in https://github.com/Slicer/ExtensionsIndex/tree/4.11.
If you want to support building the extension on your own for compatibility with Slicer 4.10 you can update your code checking slicer version such as slicer.app.majorVersion, slicer.app.minorVersion, and slicer.app.patchVersion.
If you don’t want to pollute your code with version checks then:
4.10 branch from current master4.10 branch of your extension instead of master (just in case someone builds a Slicer-4.10 version)
