Thank you and cuda issue on rtx 3070

[jvgriethuijsen]

First of all thanks so much for the wonderful work!

I think I've found a bug.
Trying the following gives an error.

model = LlamaForCausalLM.from_pretrained("TheBloke/wizardLM-7B-HF",  load_in_8bit=True,

- CUDA SETUP: WARNING! libcuda.so not found! Do you have a CUDA driver installed? If you are on a cluster, make sure you are on a CUDA machine!

I am on a windows machine (i9 / 32GB / GTX 3070 laptop 8GB vram). I tried installing an older version of cuda toolkit but it didn't work. It also seems to assume I am on Linux somehow?

CUDA SETUP: Problem: The main issue seems to be that the main CUDA library was not detected.
CUDA SETUP: Solution 1): Your paths are probably not up-to-date. You can update them via: sudo ldconfig.
CUDA SETUP: Solution 2): If you do not have sudo rights, you can do the following:
CUDA SETUP: Solution 2a): Find the cuda library via: find / -name libcuda.so 2>/dev/null
CUDA SETUP: Solution 2b): Once the library is found add it to the LD_LIBRARY_PATH: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:FOUND_PATH_FROM_2a
CUDA SETUP: Solution 2c): For a permanent solution add the export from 2b into your .bashrc file, located at ~/.bashrc

From requirements on README:

"The bitsandbytes library is currently only supported on Linux distributions. Windows is not supported at the moment."

[TimDettmers]

This issue might be resolve by upgrading via pip install -U bitsandbytes. However, note that Windows is currently not supported. You can find more information here: #30

[swumagic]

Bitsandbytes was not supported windows before, but my method can support windows.（yuhuang）
