flash-attn install failed about vgen

[8414sys]

I used this command, and it need the flash-attn.

I also use that command.
Go to the files and delete below code
files
./i2vgen-xl/tools/modules/unet/unet_i2vgen.py
./i2vgen-xl/tools/modules/unet/unet_t2v.py
./i2vgen-xl/tools/modules/unet/util.py

code to delete

from .mha_flash import FlashAttentionBlock

Then it will be work without flash-attn

Hi, it seems to be an issue with the version of CUDA, our version is 11.4.

[8414sys]

this version code doesn't use flash-attn module actually.
In my case, i don't install flash-attn module and delete all import line that contain flash-attn module.

This worked for me. Thank you!
But next, I got this problem: no kernel image is available for execution on the device.
