[MetaSchedule] Fix tune_tir crash with ScheduleError in RewriteParallelVectorizeUnroll

2

This patch fixes issue #18423 where meta_schedule.tune_tir crashes during initial population sampling when RewriteParallelVectorizeUnroll postprocessor encounters blocks that violate compact dataflow requirements. The crash occurred when: - A block reads...

[Relax][Torch] Fix from_exported_program crash with FakeTensor and lifted tensors

3

Fix Issue #18407: from_exported_program segfault with exported MHA using eq(0)/expand mask + in-place masked_fill_. Problem: When importing torch.export models with lifted tensors (e.g., from masked_fill_ operations), the conversion fails because...
