Vision: ROIAlign.h(29,30): error C2039: 'typed': is not a member of 'c10::OperatorHandle'

Trying to build the source using cmake with Visual Studio 2019 on Windows, pytorch version: 1.5.1, while compiling I get the error messages below. I have verified that e.g. typed is not a member of c10::OpeationHandle, am I mixing versions even though I use the latest torch and torchvision?

I used the command cmake --build . --config Release

Hi @simonvaj in general the master branch from torchvision depends on the master of torch. I'm not in a position to tell if that is the problem here, but could you try to install torch from source or the preview (nightly) version and see if that solves your problem?

Hi @pmeier that did help, it was easy to install the nightly version of torch using pip with flag --ignore-installed. Now I know this is the relevant version to use. Thank you very much.
