Flash-attn is an optional package, and not all models require it. Additionally, if a precompiled package for flash-attn is not available, it needs to be compiled and installed, which can be very time-consuming. Therefore, flash-attn has not been added to the requirements.

We apologize for the omission of wheel package. We will include it in the next release. We use environments created with conda, which include wheel by default, so we did not encounter this issue.

Sound reasoning. Might want to document the possibility of needing flash_attn. Great project!
