[brewswang]

ImportErrorImportError: : cannot import name 'flash_attn_unpadded_qkvpacked_func'

@brewswang Please consider renaming the function based on flash-attn2, they changed the function names.

[brewswang]

thanks,

[brewswang]

These functions have been renamed:

• flash_attn_unpadded_func -> flash_attn_varlen_func
• flash_attn_unpadded_qkvpacked_func -> flash_attn_varlen_qkvpacked_func
• flash_attn_unpadded_kvpacked_func -> flash_attn_varlen_kvpacked_func
