## 💾 Install Unsloth You can also see our documentation for more detailed installation and updating instructions [here](https://docs.unsloth.ai/get-started/installing-+-updating). ### Pip Installation **Install with pip (recommended) for Linux devices:** ``` pip install unsloth ``` **To update Unsloth:** ``` pip install --upgrade --force-reinstall --no-cache-dir unsloth unsloth_zoo ``` See [here](https://github.com/unslothai/unsloth/edit/main/README.md#advanced-pip-installation) for advanced pip install instructions. ### Windows Installation > [!warning] > Python 3.13 does not support Unsloth. Use 3.12, 3.11 or 3.10 1. **Install NVIDIA Video Driver:** You should install the latest version of your GPUs driver. Download drivers here: [NVIDIA GPU Drive](https://www.nvidia.com/Download/index.aspx). 3. **Install Visual Studio C++:** You will need Visual Studio, with C++ installed. By default, C++ is not installed with [Visual Studio](https://visualstudio.microsoft.com/vs/community/), so make sure you select all of the C++ options. Also select options for Windows 10/11 SDK. For detailed instructions with options, see [here](https://docs.unsloth.ai/get-started/installing-+-updating). 5. **Install CUDA Toolkit:** Follow the instructions to install [CUDA Toolkit](https://developer.nvidia.com/cuda-toolkit-archive). 6. **Install PyTorch:** You will need the correct version of PyTorch that is compatibile with your CUDA drivers, so make sure to select them carefully. [Install PyTorch](https://pytorch.org/get-started/locally/). 7. **Install Unsloth:** ```python pip install unsloth ``` #### Notes To run Unsloth directly on Windows: - Install Triton from this Windows fork and follow the instructions [here](https://github.com/woct0rdho/triton-windows) (be aware that the Windows fork requires PyTorch >= 2.4 and CUDA 12) - In the SFTTrainer, set `dataset_num_proc=1` to avoid a crashing issue: ```python trainer = SFTTrainer( dataset_num_proc=1, ... ) ``` #### Advanced/Troubleshooting For **advanced installation instructions** or if you see weird errors during installations: 1. Install `torch` and `triton`. Go to https://pytorch.org to install it. For example `pip install torch torchvision torchaudio triton` 2. Confirm if CUDA is installated correctly. Try `nvcc`. If that fails, you need to install `cudatoolkit` or CUDA drivers. 3. Install `xformers` manually. You can try installing `vllm` and seeing if `vllm` succeeds. Check if `xformers` succeeded with `python -m xformers.info` Go to https://github.com/facebookresearch/xformers. Another option is to install `flash-attn` for Ampere GPUs. 4. Double check that your versions of Python, CUDA, CUDNN, `torch`, `triton`, and `xformers` are compatible with one another. The [PyTorch Compatibility Matrix](https://github.com/pytorch/pytorch/blob/main/RELEASE.md#release-compatibility-matrix) may be useful. 5. Finally, install `bitsandbytes` and check it with `python -m bitsandbytes` ### Conda Installation (Optional) `⚠️Only use Conda if you have it. If not, use Pip`. Select either `pytorch-cuda=11.8,12.1` for CUDA 11.8 or CUDA 12.1. We support `python=3.10,3.11,3.12`. ```bash 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 pip install unsloth ```

If you're looking to install Conda in a Linux environment, read here, or run the below 🔽

```bash mkdir -p ~/miniconda3 wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3 rm -rf ~/miniconda3/miniconda.sh ~/miniconda3/bin/conda init bash ~/miniconda3/bin/conda init zsh ```

### Advanced Pip Installation `⚠️Do **NOT** use this if you have Conda.` Pip is a bit more complex since there are dependency issues. The pip command is different for `torch 2.2,2.3,2.4,2.5` and CUDA versions. For other torch versions, we support `torch211`, `torch212`, `torch220`, `torch230`, `torch240` and for CUDA versions, we support `cu118` and `cu121` and `cu124`. For Ampere devices (A100, H100, RTX3090) and above, use `cu118-ampere` or `cu121-ampere` or `cu124-ampere`. For example, if you have `torch 2.4` and `CUDA 12.1`, use: ```bash pip install --upgrade pip pip install "unsloth[cu121-torch240] @ git+https://github.com/unslothai/unsloth.git" ``` Another example, if you have `torch 2.5` and `CUDA 12.4`, use: ```bash pip install --upgrade pip pip install "unsloth[cu124-torch250] @ git+https://github.com/unslothai/unsloth.git" ``` And other examples: ```bash pip install "unsloth[cu121-ampere-torch240] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu118-ampere-torch240] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu121-torch240] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu118-torch240] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu121-torch230] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu121-ampere-torch230] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu121-torch250] @ git+https://github.com/unslothai/unsloth.git" pip install "unsloth[cu124-ampere-torch250] @ git+https://github.com/unslothai/unsloth.git" ``` Or, run the below in a terminal to get the **optimal** pip installation command: ```bash wget -qO- https://raw.githubusercontent.com/unslothai/unsloth/main/unsloth/_auto_install.py | python - ``` Or, run the below manually in a Python REPL: ```python try: import torch except: raise ImportError('Install torch via `pip install torch`') from packaging.version import Version as V v = V(torch.__version__) cuda = str(torch.version.cuda) is_ampere = torch.cuda.get_device_capability()[0] >= 8 if cuda != "12.1" and cuda != "11.8" and cuda != "12.4": raise RuntimeError(f"CUDA = {cuda} not supported!") if v <= V('2.1.0'): raise RuntimeError(f"Torch = {v} too old!") elif v <= V('2.1.1'): x = 'cu{}{}-torch211' elif v <= V('2.1.2'): x = 'cu{}{}-torch212' elif v < V('2.3.0'): x = 'cu{}{}-torch220' elif v < V('2.4.0'): x = 'cu{}{}-torch230' elif v < V('2.5.0'): x = 'cu{}{}-torch240' elif v < V('2.6.0'): x = 'cu{}{}-torch250' else: raise RuntimeError(f"Torch = {v} too new!") x = x.format(cuda.replace(".", ""), "-ampere" if is_ampere else "") print(f'pip install --upgrade pip && pip install "unsloth[{x}] @ git+https://github.com/unslothai/unsloth.git"') ``` ## 📜 Documentation - Go to our official [Documentation](https://docs.unsloth.ai) for saving to GGUF, checkpointing, evaluation and more! - We support Huggingface's TRL, Trainer, Seq2SeqTrainer or even Pytorch code! - We're in 🤗Hugging Face's official docs!
