Error while installing open_lm for apple/DCLM-7B model

Hello guys, i tried to install open_lm in order to use apple’s DCLM-7B model but when i try to install git+https://github.com/mlfoundations/open_lm.git i get the following errors :

ERROR: Failed building wheel for xformers
ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (xformers)

Has anyone encountered the same issue ?
Please let me know if you have a solution.

Forget it, i just had to install formers directly :
CC=gcc-11 CXX=g+±11 pip3 install xformers
