Upgrade from 1.8.1 to 1.9.0: missing function in dll


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
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


several times and get the same error.

Can anyone offer a diagnosis, or any advice please?



I noticed this is still a problem, can anyone help?
