Hi,
I have been using libtorch 1.8.1 with cuda 11.1 in visual studio 2019 with no problems. I tried converting to use libtorch 1.9.0 (cuda 11.1 as well); no changes to my code, all I am altering is include and link paths.
Everything builds and links, but there is a runtime error:


The procedure entry point
??1AutoDispatchBelowADInplaceOrView@at@@QEAA@XZ
could not be located in the dynamic link library

and a quick google shows this is a libtorch function.
I have tried downloading libtorch 1.9.0 from
https://download.pytorch.org/libtorch/cu111/libtorch-win-shared-with-deps-1.9.0%2Bcu111.zip 3
several times and get the same error.
Can anyone offer a diagnosis, or any advice please?
Steve.
