Thanks for the reply!
That did not fix it.
I stumbled upon this documenation 7 from Doxygen, which I’m aware Pytorch uses per CONTRIBUTING.md
You can see the _cvtu32_mask16 function is specified there.
This is definitely beyond my realm of expertise ><.  I commented on an issue on the github project but I wasn’t sure if that was the right place. It appears someone else is getting the same issue and it happened very recently.
