Intel® XPU Library for PyTorch* Ecosystem Projects

This project contains a set of plugins for PyTorch* ecosystem libraries which enable hardware acceleration on Intel® GPUs thru the xpu PyTorch* device backend. The goal of the project is to:

• Facilitate enabling of the Intel® GPUs support across PyTorch* ecosystem projects
• Provide the plugins till the support for Intel® GPUs will be accepted in the respective upstream projects

At the moment project provides plugins for the following frameworks:

• Intel® XPU plugin for TorchCodec

Plugins

Intel® XPU plugin for TorchCodec

TorchCodec is a high-performance Python library designed for media processing (decoding and encoding) using PyTorch* tensors. Intel® XPU plugin for TorchCodec enables hardware acceleration for video operations (only decoding at the moment) on Linux. Both TorchCodec and Intel® plugin rely on the FFmpeg libraries for their operations which must be pre-installed on the system. Intel® plugin further assumes that FFmpeg is built with the VAAPI support.

To use Intel® XPU plugin for TorchCodec, load it in the Python script and pass XPU device to initialize TorchCodec decoder or encoder:

import torchcodec
import torchcodec_xpu

decoder = torchcodec.decoders.VideoDecoder(
    "input.mp4", device="xpu:0")

Build from sources

• Install uv

• Install oneAPI 2025.3

• Install FFmpeg development environment with enabled VAAPI hardware acceleration. For example:

  • By installing FFmpeg provided by your Linux distribution. For Ubuntu:

apt-get update && apt-get install -y \
    libavcodec-dev \
    libavdevice-dev \
    libavfilter-dev \
    libavformat-dev \
    libavutil-dev \
    libswresample-dev \
    libswscale-dev

• By self-building FFmpeg from sources:

git clone https://git.ffmpeg.org/ffmpeg.git && cd ffmpeg
./configure \
  --prefix=$HOME/_install \
  --libdir=$HOME/_install/lib \
  --disable-static \
  --disable-stripping \
  --disable-doc \
  --enable-shared \
  --enable-vaapi
make -j$(nproc) && make install

export PKG_CONFIG_PATH=$HOME/_install/lib/pkgconfig
export LD_LIBRARY_PATH=$HOME/_install/lib:$LD_LIBRARY_PATH

• Build and install plugins supplied by Intel® XPU Library for PyTorch* Ecosystem Projects:

git clone https://github.com/intel/torchlib-xpu.git && cd torchlib-xpu

uv venv && uv pip install torch -e . \
