That was actually really close to the problem I was having! I had created a new conda environment and needed to install cuda toolkit in that new environment. I always assumed cuda tool kit was a system-wide package but that doesn't seem to be the case.

[muelletm]

Just in case this is helpful for someone:

If you get this with docker make sure to use an image with cuda toolkit installed, e.g.:

pytorch/pytorch:2.0.1-cuda11.7-cudnn8-devel

I solved this by "conda install cudatoolkit=11.7 -y".

[DanielLeung222]

For me, I just replace libbitsandbytes_cpu.so to be libbitsandbytes_cuda117.so, which 117 is the cuda vision that I am now using.

You may refer to this link: bitsandbytes-foundation/bitsandbytes#156 (comment)
They have undefined symbol error but with a different symbol, and it can be solved by this method.

[harigovind511]

I faced the same issue today, turns it I had a version conflict between Cuda and PyTorch. A fresh install of Cuda and PyTorch did the trick for me.

[chensaics]

you can try this method:

cd [your bitsandbytes env path]
eg. : cd /home/server/anaconda3/envs/qlora/lib/python3.11/site-packages/bitsandbytes/
you can copy the path from your terminal

then:
cp libbitsandbytes_cuda117.so libbitsandbytes_cpu.so

ps : "CUDA version 117" is your cuda version, so here is " libbitsandbytes_cuda117.so"

[r4dm]

cp libbitsandbytes_cuda117.so libbitsandbytes_cpu.so

This method worked for me in WSL Ubuntu on Windows11. I installed anacoda3 and cuda118 special version for WSL2

FineTuning Vicuna-13B with QloRA works well on RTX4090

[wyxscir]

i solved it by repip the "bitsandbytes"
