Cannot install unsloth with bitsandbytes problem

[JJS-L]

Centos x86_64

Python 3.11.11

torch 2.5.1

cuda 12.1

I want to install unsloth in Linux, but I cannot download directly from GitHub，I use the zip to setup unsloth .Here, I'm stuck with the problem, I typed in the following command.

conda create --name unsloth_env
python=3.11
pytorch-cuda=12.1
pytorch cudatoolkit xformers -c pytorch -c nvidia -c xformers
-y
conda activate unsloth_env

where, I cd /unsloth_main #which is the unzipped zip file

pip install ".[cu121-torch250]

Then, the following error occurs
@

And I'm taking the update the Bitsangbytes from 0.42 to 0.44.2, but I'm in trouble again.

ERROR: bitsandbytes-0.44.2.dev0-py3-none-manylinux_2_24_x86_64.whl is not a supported wheel on this platform.

I don't konw how to solve

Hi there. CentOS is not supported by our binary wheels as it is past end of life.
You may have some luck building from source, but we are not able to provide future source compatibility guarantees or support for it.

Oh! Thank you so much for responding to my quesion. I seem to have successfully installed unsloth in a conda environment without reporting this problem, but I have other problems. I still have the problem when I install it in another environment and I don't know why this is
