Changes
Int4XPULayoutandZeroPointDomainsetup —Int4WeightOnlyConfignow handles these internally.Int4WeightOnlyOpaqueTensorConfigwithPrototypeInt4WeightOnlyConfig..to()fix: Split.to(device, dtype)into.to(device).to(dtype)to avoid incorrect casting.Why
torchao updated its APIs: XPU int4 config now auto-handles layout/zero-point internally, CPU int4 config was renamed and moved to a new module path. The
.to()chaining fix ensures device placement and dtype casting are applied correctly.
