Please check that this issue hasn't been reported before.

  • I searched previous Bug Reports didn't find any similar reports.

Expected Behavior

No error

Current behaviour

Seems like upstream requires https://github.com/Dao-AILab/flash-attention/pull/2689

Running it forced via 4.6.0 seems fine for smoke test, but I haven't done extensive test yet. Some warnings are thrown for the NamedTuple.

Steps to reproduce

  1. Install FA4
  2. Install cutlass 4.6.0
