Can anyone explain why the attn_mask_enabled option is set to False?

F5-TTS/src/f5_tts/configs/F5TTS_v1_Base.yaml

Line 36 in 69b0e01

attn_mask_enabled: False

I believe it should be True. Is there any performance impact from this?

• 1.1.5...1.1.6

In short, we add fla support for case using mask (1.1.5->1.1.6). If vanilla torch backend, likely cuda oom and much slower; previously sort samples and disable mask.
