Install 2.7.3 and 3.0.0b1 in same virtual environment

[quanta42]

Hello,

I encountered an issue when trying to install both flash-attn versions 2.7.3 and 3.0.0b1 in the same virtual environment. The problem seems to arise because both versions now use the same package name (flash-attn), which leads to conflicts during installation.

Additionally, I noticed that in the past, the package name for the hopper directory was flashattn-hopper, which avoided such conflicts. The recent change to unify the package name across versions appears to have reintroduced this issue.

I also found that building a wheel and installing it with pip works better than invoking setup.py directly, which tends to produce .egg files and can cause further complications.

Could you please clarify the intended approach for installing both versions in the same environment? Should users manually rename the packages, or is there a recommended way to handle this scenario?

Thank you for your guidance!

I've changed the package name so now you should be able to install both in the same environment
