the above model descriptor definition will give the following validation error:

Initially I got this issue when testing tiktorch on a windows platform https://github.com/ilastik/tiktorch/actions/runs/10905374847/job/30264149619. Also I noticed we don't have window ci running, we plan to support all platforms right? It is worth noting that for macos and linux platforms, there isn't such validation error ...
