Unable to run this in Windows 11 WSL (Ubuntu)

[cleverestx]

I get this when completing all the steps for install and then launching infer_single.sh (note: it did complete building Flash_attn without error)

(fantasyportrait) cleverestx@clevbox-mini:~/fantasy-portrait$ bash infer_single.sh

Help?

Hi, @cleverestx
This is because there is a problem with your installation of flash attention. Recompiling and installing flash attention correctly can solve the problem.
