1. CUDA driver not installed
2. CUDA not installed
3. You have multiple conflicting CUDA libraries

CUDA SETUP: The CUDA version for the compile might depend on your conda install. Inspect CUDA version via conda list | grep cuda. ================================================================================

Please run the following command to get more information:

    python -m bitsandbytes

    Inspect the output of the command and see if you can locate CUDA libraries. You might need to add them
    to your LD_LIBRARY_PATH. If you suspect a bug, please take the information from python -m bitsandbytes
    and open an issue at: https://github.com/TimDettmers/bitsandbytes/issues

Expected behavior

That it should have detected the GPU and worked on it.

@gauravjoshi2034 What version of bitsandbytes are you trying this with? It looks to me like it might be <=0.38.0. I just tried on a T4 Colab and it works for me with the latest 0.42.0 release. If you can upgrade to >=0.40.0 then that should solve your issue.

@gauravjoshi2034 is your problem solved or no longer an issue? it would be good to close this issue if it no longer requires attention of others. Thank you.
