I have tried installing flash-atten in an empty conda environment, however it fails with an error which I don’t understand that.

(fatten) [m@login03 ~]$ conda install conda-forge::flash-attn

The system information is shown below:

conda 4.12.0
(fatten) [m@login03 ~]$ conda list

(fatten) [m@login03 ~]$

Any idea about that?

@mahmoodn,

It looks like the version of glibc and cuda on your system are incompatible with the package you are trying to install. You will need to update those in order to install this package.

We also recommend updating to the latest version of conda to get the best experience (24.9.2). We have more detailed information available in the error messages that could help you further debug your problem.
