### From source

You need CMake and Python installed. For Linux, make sure to install a compiler (`apt install build-essential`, for example).

```bash
git clone https://github.com/TimDettmers/bitsandbytes.git && cd bitsandbytes/
cmake -B build -DBUILD_CUDA=ON -S .
pip install -r requirements-dev.txt
cmake -DCOMPUTE_BACKEND=cuda -S .
make
pip install .
```
Note support for non-CUDA GPUs (e.g. AMD, Intel), is also coming soon.
Note support for non-CUDA GPUs (e.g. AMD, Intel, Apple Silicon), is also coming soon.
For a more detailed compilation guide, head to the [dedicated page on the topic](./compiling)

## Windows

Windows builds require Visual Studio with C++ support, as well as the Cuda SDK installed.

Currently for Windows users, you need to build bitsandbytes from source:

```bash
git clone https://github.com/TimDettmers/bitsandbytes.git && cd bitsandbytes/
cmake -B build -DBUILD_CUDA=ON -S .
cmake --build build --config Release
cmake -DCOMPUTE_BACKEND=cuda -S .
cmake --build . --config Release
python -m build --wheel

I left it as it is since I can't verify this. Can someone with access to a windows VM double check these?

This works for me with pip install ..

Alternatively with building the wheel, this also works:

python -m build --wheel
pip install dist/bitsandbytes-0.43.0.dev0-cp311-cp311-win_amd64.whl

```
