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, there're several prerequisite steps for tools installation and environment preparation:

  • Step 1: Install Visual Studio 2022 Community Edition and select "Desktop development with C++" workload, like this

  • Step 2: Install or update to latest GPU driver

  • Step 3 (Recommended): Install Miniconda for Python environment management. Choose Miniconda installer for Windows.

  • Step 4: Install Intel® oneAPI Base Toolkit 2024.0:

    First, Create a Python 3.11 enviroment and activate it. In Anaconda Prompt:

    conda create -n llm python=3.11 libuv

conda activate llm

    .. important::

   ``ipex-llm`` is tested with Python 3.9, 3.10 and 3.11. Python 3.11 is recommended for best practices.

    Then, use pip to install the Intel oneAPI Base Toolkit 2024.0:

    pip install dpcpp-cpp-rt==2024.0.2 mkl-dpcpp==2024.0.0 onednn==2024.0.0

Install IPEX-LLM

Install IPEX-LLM From PyPI

The easiest ways to install ipex-llm is the following commands, choosing either US or CN website for extra-index-url:

.. tabs::
   .. tab:: US

      .. code-block:: cmd

         conda activate llm

         pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/

   .. tab:: CN

      .. code-block:: cmd

         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.

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:

.. tabs::
   .. tab:: Intel iGPU

      .. code-block:: cmd

         set SYCL_CACHE_PERSISTENT=1
         set BIGDL_LLM_XMX_DISABLED=1

   .. tab:: Intel Arc™ A-Series

      .. code-block:: 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 you have completed the following steps:

  • Ensure that you have installed Visual Studio with "Desktop development with C++" workload.

  • Make sure that the correct version of oneAPI, specifically 2024.0, is installed.

  • Ensure that libuv is installed in your conda environment. This can be done during the creation of the environment with the command:

    conda create -n llm python=3.11 libuv

    If you missed libuv, you can add it to your existing environment through

    conda install libuv

Linux

Prerequisites

IPEX-LLM GPU support on Linux has been verified on:

  • Intel Arc™ A-Series Graphics
  • Intel Data Center GPU Flex Series
  • Intel Data Center GPU Max Series
.. important::

    IPEX-LLM on Linux supports PyTorch 2.0 and PyTorch 2.1.

.. important::

    We currently support the Ubuntu 20.04 operating system and later.

.. tabs::
   .. tab:: PyTorch 2.1

      To enable IPEX-LLM for Intel GPUs with PyTorch 2.1, here are several prerequisite steps for tools installation and environment preparation:


      * Step 1: Install Intel GPU Driver version >= stable_775_20_20231219. We highly recommend installing the latest version of intel-i915-dkms using apt.

        .. seealso::

           Please refer to our `driver installation <https://dgpu-docs.intel.com/driver/installation.html>`_ for general purpose GPU capabilities.

           See `release page <https://dgpu-docs.intel.com/releases/index.html>`_ for latest version.

      * Step 2: Download and install `Intel® oneAPI Base Toolkit <https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html>`_ with version 2024.0. OneDNN, OneMKL and DPC++ compiler are needed, others are optional.

      Intel® oneAPI Base Toolkit 2024.0 installation methods:

      .. tabs::
         .. tab:: PIP installer

            Step 1: Install oneAPI in a user-defined folder, e.g., ``~/intel/oneapi``.

            .. code-block:: bash

               export PYTHONUSERBASE=~/intel/oneapi
               pip install dpcpp-cpp-rt==2024.0.2 mkl-dpcpp==2024.0.0 onednn==2024.0.0 --user

            .. note::

               The oneAPI packages are visible in ``pip list`` only if ``PYTHONUSERBASE`` is properly set.

            Step 2: Configure your working conda environment (e.g. with name ``llm``) to append oneAPI path (e.g. ``~/intel/oneapi/lib``) to the environment variable ``LD_LIBRARY_PATH``.

            .. code-block:: bash

               conda env config vars set LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/intel/oneapi/lib -n llm

            .. note::
               You can view the configured environment variables for your environment (e.g. with name ``llm``) by running ``conda env config vars list -n llm``.
               You can continue with your working conda environment and install ``ipex-llm`` as guided in the next section.

            .. note::

               You are recommended not to install other pip packages in the user-defined folder for oneAPI (e.g. ``~/intel/oneapi``).
               You can uninstall the oneAPI package by simply deleting the package folder, and unsetting the configuration of your working conda environment (e.g., with name ``llm``).
               
               .. code-block:: bash
               
                  rm -r ~/intel/oneapi

      Then you may install directly from the wheel archives using following commands:

      .. code-block:: 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]


.. 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.

To use GPU acceleration on Linux, several environment variables are required or recommended before running a GPU example.

.. tabs::
   .. tab:: 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:

      .. code-block:: 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

   .. tab:: Intel Data Center GPU Max

      For Intel Data Center GPU Max Series, we recommend:

      .. code-block:: 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``

   .. tab:: Intel iGPU

      .. code-block:: 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
         export BIGDL_LLM_XMX_DISABLED=1

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 or before importing IPEX package.

  • 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 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.
