# IPEX-LLM Installation: GPU
## Windows
### Prerequisites
IPEX-LLM on Windows supports Intel iGPU and dGPU.
> [!IMPORTANT]
> IPEX-LLM on Windows only supports PyTorch 2.1.
To apply Intel GPU acceleration, please first verify your GPU driver version.
> [!NOTE]
> The GPU driver version of your device can be checked in the "Task Manager" -> GPU 0 (or GPU 1, etc.) -> Driver version.
If you have driver version lower than `31.0.101.5122`, it is required to [**update your GPU driver to the latest**](https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html).
### Install IPEX-LLM
#### Install IPEX-LLM From PyPI
We recommend using [Miniforge](https://conda-forge.org/download/) to create a python 3.11 enviroment.
> [!IMPORTANT]
> ``ipex-llm`` is tested with Python 3.9, 3.10 and 3.11. Python 3.11 is recommended for best practices.
The easiest ways to install `ipex-llm` is the following commands.

```cmd
conda create -n llm python=3.11 libuv
conda activate llm
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
```
- For **CN**:
```cmd
conda create -n llm python=3.11 libuv
conda activate llm
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/cn/
```
#### Install IPEX-LLM From Wheel
If you encounter network issues when installing IPEX, you can also install IPEX-LLM dependencies for Intel XPU from source archives. First you need to download and install torch/torchvision/ipex from wheels listed below before installing `ipex-llm`.
- For **Intel Core™ Ultra Processers (Series 2) with processor number 2xxV (code name Lunar Lake)**:
Download the wheels on Windows system:
```
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/lnl/torch-2.3.1%2Bcxx11.abi-cp311-cp311-win_amd64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/lnl/torchvision-0.18.1%2Bcxx11.abi-cp311-cp311-win_amd64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/lnl/intel_extension_for_pytorch-2.3.110%2Bxpu-cp311-cp311-win_amd64.whl
```
You may install dependencies directly from the wheel archives and then install `ipex-llm` using following commands:
```
pip install torch-2.3.1+cxx11.abi-cp311-cp311-win_amd64.whl
pip install torchvision-0.18.1+cxx11.abi-cp311-cp311-win_amd64.whl
pip install intel_extension_for_pytorch-2.3.110+xpu-cp311-cp311-win_amd64.whl
pip install --pre --upgrade ipex-llm[xpu_lnl]
```
- For **other Intel iGPU and dGPU**:
Download the wheels on Windows system:
```
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torch-2.1.0a0%2Bcxx11.abi-cp311-cp311-win_amd64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torchvision-0.16.0a0%2Bcxx11.abi-cp311-cp311-win_amd64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/intel_extension_for_pytorch-2.1.10%2Bxpu-cp311-cp311-win_amd64.whl
```
You may install dependencies directly from the wheel archives and then install `ipex-llm` using following commands:
```
pip install torch-2.1.0a0+cxx11.abi-cp311-cp311-win_amd64.whl
pip install torchvision-0.16.0a0+cxx11.abi-cp311-cp311-win_amd64.whl
pip install intel_extension_for_pytorch-2.1.10+xpu-cp311-cp311-win_amd64.whl
pip install --pre --upgrade ipex-llm[xpu]
```
> [!NOTE]
> All the wheel packages mentioned here are for Python 3.11. If you would like to use Python 3.9 or 3.10, you should modify the wheel names for ``torch``, ``torchvision``, and ``intel_extension_for_pytorch`` by replacing ``cp11`` with ``cp39`` or ``cp310``, respectively.
### Runtime Configuration
To use GPU acceleration on Windows, several environment variables are required before running a GPU example:
- For **Intel iGPU** and **Intel Arc™ A-Series Graphics**:
```cmd
set SYCL_CACHE_PERSISTENT=1
```
> [!NOTE]
> For **the first time** that **each model** runs on Intel iGPU/Intel Arc™ A300-Series or Pro A60, it may take several minutes to compile.
### Troubleshooting
#### 1. Error loading `intel_extension_for_pytorch`
If you met error when importing `intel_extension_for_pytorch`, please ensure that `libuv` is installed in your conda environment. This can be done during the creation of the environment with the command:
```cmd
conda create -n llm python=3.11 libuv
```
If you missed `libuv`, you can add it to your existing environment through
```cmd
conda install libuv
```

```
#### Install IPEX-LLM From Wheel
If you encounter network issues when installing IPEX, you can also install IPEX-LLM dependencies for Intel XPU from source archives. First you need to download and install torch/torchvision/ipex from wheels listed below before installing `ipex-llm`.
- For **PyTorch 2.1**:
```bash
# get the wheels on Linux system for IPEX 2.1.10+xpu
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torch-2.1.0a0%2Bcxx11.abi-cp311-cp311-linux_x86_64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torchvision-0.16.0a0%2Bcxx11.abi-cp311-cp311-linux_x86_64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/intel_extension_for_pytorch-2.1.10%2Bxpu-cp311-cp311-linux_x86_64.whl
```
Then you may install directly from the wheel archives using following commands:
```bash
# install the packages from the wheels
pip install torch-2.1.0a0+cxx11.abi-cp311-cp311-linux_x86_64.whl
pip install torchvision-0.16.0a0+cxx11.abi-cp311-cp311-linux_x86_64.whl
pip install intel_extension_for_pytorch-2.1.10+xpu-cp311-cp311-linux_x86_64.whl
# install ipex-llm for Intel GPU
pip install --pre --upgrade ipex-llm[xpu]
```
- For **PyTorch 2.0** (deprecated for versions ``ipex-llm >= 2.1.0b20240511``):
```bash
# get the wheels on Linux system for IPEX 2.0.110+xpu
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torch-2.0.1a0%2Bcxx11.abi-cp311-cp311-linux_x86_64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/torchvision-0.15.2a0%2Bcxx11.abi-cp311-cp311-linux_x86_64.whl
wget https://intel-extension-for-pytorch.s3.amazonaws.com/ipex_stable/xpu/intel_extension_for_pytorch-2.0.110%2Bxpu-cp311-cp311-linux_x86_64.whl
```
Then you may install directly from the wheel archives using following commands:
```bash
# install the packages from the wheels
pip install torch-2.0.1a0+cxx11.abi-cp311-cp311-linux_x86_64.whl
pip install torchvision-0.15.2a0+cxx11.abi-cp311-cp311-linux_x86_64.whl
pip install intel_extension_for_pytorch-2.0.110+xpu-cp311-cp311-linux_x86_64.whl
# install ipex-llm for Intel GPU
pip install --pre --upgrade ipex-llm[xpu_2.0]==2.1.0b20240510
```
> [!NOTE]
> All the wheel packages mentioned here are for Python 3.11. If you would like to use Python 3.9 or 3.10, you should modify the wheel names for ``torch``, ``torchvision``, and ``intel_extension_for_pytorch`` by replacing ``cp11`` with ``cp39`` or ``cp310``, respectively.
### Runtime Configuration
To use GPU acceleration on Linux, several environment variables are required or recommended before running a GPU example.
- For **Intel Arc™ A-Series and Intel Data Center GPU Flex**:
For Intel Arc™ A-Series Graphics and Intel Data Center GPU Flex Series, we recommend:
```bash
# Configure oneAPI environment variables. Required step for APT or offline installed oneAPI.
# Skip this step for PIP-installed oneAPI since the environment has already been configured in LD_LIBRARY_PATH.
source /opt/intel/oneapi/setvars.sh
# Recommended Environment Variables for optimal performance
export USE_XETLA=OFF
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
export SYCL_CACHE_PERSISTENT=1
```
- For **Intel Data Center GPU Max**:
For Intel Data Center GPU Max Series, we recommend:
```bash
# Configure oneAPI environment variables. Required step for APT or offline installed oneAPI.
# Skip this step for PIP-installed oneAPI since the environment has already been configured in LD_LIBRARY_PATH.
source /opt/intel/oneapi/setvars.sh
# Recommended Environment Variables for optimal performance
export LD_PRELOAD=${LD_PRELOAD}:${CONDA_PREFIX}/lib/libtcmalloc.so
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
export SYCL_CACHE_PERSISTENT=1
export ENABLE_SDP_FUSION=1
```
Please note that ``libtcmalloc.so`` can be installed by ``conda install -c conda-forge -y gperftools=2.10``
- For **Intel iGPU**:
```bash
# Configure oneAPI environment variables. Required step for APT or offline installed oneAPI.
# Skip this step for PIP-installed oneAPI since the environment has already been configured in LD_LIBRARY_PATH.
source /opt/intel/oneapi/setvars.sh
export SYCL_CACHE_PERSISTENT=1
```
> [!NOTE]
> For **the first time** that **each model** runs on Intel iGPU/Intel Arc™ A300-Series or Pro A60, it may take several minutes to compile.
### Known issues
#### 1. Potential suboptimal performance with Linux kernel 6.2.0
For Ubuntu 22.04 and driver version < stable_775_20_20231219, the performance on Linux kernel 6.2.0 is worse than Linux kernel 5.19.0. You can use `sudo apt update && sudo apt install -y intel-i915-dkms intel-fw-gpu` to install the latest driver to solve this issue (need to reboot OS).
Tips: You can use `sudo apt list --installed | grep intel-i915-dkms` to check your intel-i915-dkms's version, the version should be latest and >= `1.23.9.11.231003.15+i19-1`.
#### 2. Driver installation unmet dependencies error: intel-i915-dkms
The last apt install command of the driver installation may produce the following error:
```
The following packages have unmet dependencies:
intel-i915-dkms : Conflicts: intel-platform-cse-dkms
Conflicts: intel-platform-vsec-dkms
```
You can use `sudo apt install -y intel-i915-dkms intel-fw-gpu` to install instead. As the intel-platform-cse-dkms and intel-platform-vsec-dkms are already provided by intel-i915-dkms.
### Troubleshooting
#### 1. Cannot open shared object file: No such file or directory
Error where libmkl file is not found, for example,
```
OSError: libmkl_intel_lp64.so.2: cannot open shared object file: No such file or directory
```
```
Error: libmkl_sycl_blas.so.4: cannot open shared object file: No such file or directory
```
The reason for such errors is that oneAPI has not been initialized properly before running IPEX-LLM code.
* For oneAPI installed using APT or Offline Installer, make sure you execute `setvars.sh` of oneAPI Base Toolkit before running IPEX-LLM.
* For PIP-installed oneAPI, activate your working environment and run ``echo $LD_LIBRARY_PATH`` to check if the installation path is properly configured for the environment. If the output does not contain oneAPI path (e.g. ``~/intel/oneapi/lib``), check [Prerequisites](#prerequisites-1) to re-install oneAPI with PIP installer.
* Make sure you install matching versions of ipex-llm/pytorch/IPEX and oneAPI Base Toolkit. IPEX-LLM with PyTorch 2.1 should be used with oneAPI Base Toolkit version 2024.0. IPEX-LLM with PyTorch 2.0 should be used with oneAPI Base Toolkit version 2023.2.
#### 2. `core dump` when running with GPU
If encountered random `core dump` when running with GPU, please remove out of tree driver.
```
sudo apt purge -y intel-i915-dkms intel-fw-gpu
```
