Hello,
actual torch2.xxx+cu128 got updated from 2.7.0+cu128 to torch2.7.1+cu128
is there a version of your builds, which can be installed there?

Thanks
(and thanks for all other stuff you do, and bringing things to work.., just sayin')

HI there.

Xformers now supports officialy latest torch 2.7.0, 2.7.1 should work IIRC. CMIIW though.
