SOLVED: PyTorch 2.7.1+XPU Intel Arc Graphics Complete Setup Guide (Linux)"

Went down a bit of an AI tech support rabbit hole. 10 hours later I thought I’d share the bottom. This is a low effort AI post. Just hoping it saves people some time. This will likely be a drive by XD

:white_check_mark: SOLVED: PyTorch 2.7.1+XPU on Intel Arc Graphics - Complete Setup Guide

:tada: SUCCESS! PyTorch XPU Working on Intel Arc Graphics

After extensive troubleshooting, I’ve successfully got PyTorch XPU working with Intel Arc Graphics on Linux. Sharing the complete solution to help others facing similar issues.

Quick Verification:

import torch
print(f"PyTorch version: {torch.__version__}")
print(f"XPU compiled: {torch._C._xpu_getDeviceCount is not None}")
print(f"XPU available: {torch.xpu.is_available()}")
print(f"Device count: {torch.xpu.device_count()}")
print(f"Device name: {torch.xpu.get_device_name(0)}")

# Test tensor creation
x = torch.randn(3, 3, device='xpu')
print(f"Test tensor: {x.size()} {x.device}")

Output:

PyTorch version: 2.7.1+xpu
XPU compiled: True
XPU available: True
Device count: 1
Device name: Intel(R) Arc(TM) Graphics
Test tensor: torch.Size([3, 3]) xpu:0

:wrench: Working Installation Command

The solution that worked after 8 full conversations of iterations of troubleshooting: Approx 10 hours. (Point and laugh if you must, I am 6 months into my 100% Linux daily driver journey XD)

# IMPORTANT: Complete clean uninstall first
pip uninstall -y torch torchvision torchaudio intel-cmplr-lib-rt intel-cmplr-lib-ur intel-cmplr-lic-rt intel-sycl-rt pytorch-triton-xpu tcmlib umf intel-pti

# Fresh install with all Intel runtime dependencies
pip install torch==2.7.1+xpu torchvision==0.22.1+xpu torchaudio==2.7.1+xpu intel-cmplr-lib-rt intel-cmplr-lib-ur intel-cmplr-lic-rt intel-sycl-rt pytorch-triton-xpu tcmlib umf intel-pti --index-url https://download.pytorch.org/whl/xpu --extra-index-url https://pypi.org/simple

:light_bulb: Key Breakthrough Discovery

The Root Cause: Partial installations and version mixing between system packages and pip packages caused library path conflicts.

The Solution: Complete clean slate reinstallation of the entire PyTorch XPU + Intel runtime stack.

:desktop_computer: System Specifications

  • Hardware: Intel Meteor Lake-P with integrated Arc Graphics
  • OS: Arch Linux (kernel 6.x)
  • Python: 3.11.6 via pyenv
  • GPU: Intel Arc Graphics (128 compute units)
  • Driver: i915 with GuC/HuC firmware

:clipboard: Prerequisites

  1. System Level Zero (install via package manager):

    # Arch Linux
sudo pacman -S level-zero-loader level-zero-headers

# Ubuntu/Debian
sudo apt install level-zero level-zero-dev

  2. Intel Compute Runtime (should be installed automatically with modern kernels)

  3. Verify GPU Detection:

    ls /dev/dri/  # Should show renderD128 or similar
clinfo        # Should list Intel GPU (if OpenCL tools installed)

:warning: Critical Success Factors

1. Use PyTorch 2.7.1+xpu (Not IPEX)

  • PyTorch 2.7.1+xpu has native Intel GPU support
  • No need for Intel Extension for PyTorch (IPEX)
  • XPU backend is built-in

2. Install ALL Intel Runtime Dependencies

The pip command above installs these essential Intel 2025.0.4 runtime components:

  • intel-cmplr-lib-rt-2025.0.4
  • intel-cmplr-lib-ur-2025.0.4
  • intel-cmplr-lic-rt-2025.0.4
  • intel-sycl-rt-2025.0.4
  • pytorch-triton-xpu-3.3.1

3. Clean Slate Installation

  • Don’t try to update existing installations
  • Uninstall everything PyTorch and Intel-related first
  • Fresh installation resolves library conflicts

:bug: Common Issues & Solutions

Issue: “XPU is not available”

Solution: Make sure you installed from the XPU index URL and included all Intel runtime dependencies.

Issue: Segmentation faults or crashes

Solution: Version conflicts between system and pip packages. Do complete uninstall/reinstall.

Issue: ImportError for Intel libraries

Solution: Install all Intel runtime dependencies listed in the command above.

Issue: Level Zero version warnings

Note: Version mismatch warnings between PyTorch expectations and system Level Zero are usually non-critical if basic tensor operations work.

:rocket: Validation Steps

After installation, verify everything works:

import torch

# Basic checks
assert torch.xpu.is_available(), "XPU not available"
assert torch.xpu.device_count() > 0, "No XPU devices found"

# Create and operate on XPU tensor
x = torch.randn(1000, 1000, device='xpu')
y = torch.randn(1000, 1000, device='xpu')
z = torch.mm(x, y)  # Matrix multiplication on GPU

print(f"✅ Success! Tensor device: {z.device}")
print(f"✅ GPU: {torch.xpu.get_device_name(0)}")

:chart_increasing: What This Enables

With working PyTorch XPU, you can now:

  • Train neural networks on Intel GPU
  • Accelerate tensor computations
  • Use Intel Arc Graphics for AI workloads
  • Develop with native PyTorch GPU support

lulz. I’m the first person this post helped. I had to point the ai at it to get the stuff working again after another install broke it :stuck_out_tongue: Thanks past self! X) (Hello future self? Back AGAIN?!)

Holy heck, this actually worked… On Windows 11 none the less, which makes it that more impressive!!!

Cheers!

Thrilled to hear that! Thanks very much for letting me know.

Man, you are great! This guide works perfect and saved me a bunch of hours trying to find the proper versions. I mentioned your guide in a bug report for Automatic1111, hoping it helps a lot more people

I’m really glad to hear that! And thanks for the kind words. I wish support for this hardware was better. Feeling like a slightly foolish early adopter at this point.

Had the AI revisit this, same deal just refactored basically:

PyTorch XPU Setup Guide for Intel Arc Graphics

What this enables: Use your Intel Arc Graphics (integrated or discrete) to accelerate PyTorch operations - train neural networks, run AI models, and perform tensor computations on your Intel GPU instead of just CPU.

Important note: This requires manual code changes to use the Intel GPU. Most existing AI applications won’t automatically benefit - they need to be specifically modified to support Intel XPU devices.

1. Prerequisites

Install Level Zero support and verify your Intel GPU is detected:

# Install Level Zero (choose your distro)
# Arch Linux:
sudo pacman -S level-zero-loader level-zero-headers
# Ubuntu/Debian:
sudo apt install level-zero level-zero-dev

# Verify Intel GPU detection
ls /dev/dri/  # Should show renderD128 or similar device files

2. Installation

Complete clean installation to avoid version conflicts (works in fish shell):

# Clean uninstall of existing packages
pip uninstall -y torch torchvision torchaudio intel-cmplr-lib-rt intel-cmplr-lib-ur intel-cmplr-lic-rt intel-sycl-rt pytorch-triton-xpu tcmlib umf intel-pti

# Fresh install with all Intel runtime dependencies
pip install torch==2.7.1+xpu torchvision==0.22.1+xpu torchaudio==2.7.1+xpu intel-cmplr-lib-rt intel-cmplr-lib-ur intel-cmplr-lic-rt intel-sycl-rt pytorch-triton-xpu tcmlib umf intel-pti --index-url https://download.pytorch.org/whl/xpu --extra-index-url https://pypi.org/simple

3. Confirmation

Verify PyTorch can detect and use your Intel GPU:

import torch

# Check XPU availability and device info
print(f"PyTorch version: {torch.__version__}")
print(f"XPU available: {torch.xpu.is_available()}")
print(f"Device count: {torch.xpu.device_count()}")
print(f"Device name: {torch.xpu.get_device_name(0)}")

# Test actual GPU computation
x = torch.randn(1000, 1000, device='xpu')
y = torch.randn(1000, 1000, device='xpu')
result = torch.mm(x, y)  # Matrix multiplication on Intel GPU
print(f"✅ GPU computation successful on: {result.device}")

Expected output:

PyTorch version: 2.7.1+xpu
XPU available: True
Device count: 1
Device name: Intel(R) Arc(TM) Graphics
✅ GPU computation successful on: xpu:0

If you see this output, PyTorch can successfully use your Intel Arc Graphics for GPU acceleration.

Remember: You’ll need to explicitly specify device='xpu' in your PyTorch code to actually use the Intel GPU - it won’t happen automatically.

That seems very odd. I’m stumbling about the “important note” and the “remember” sentence. Could you please specify which AI you used on that?
Your Guide in the first topic works flawless as expected, but there is no need to change any “PyTorch code”.

What I found is a special behavior in the way Automatic1111 (a webUI for Stable Diffusion) detects the hardware abilities of the used GPU, especially for Intel GPUs (XPU Devices). To make Automatic1111 work propper with Intel GPU, you have to modify it’s code but this has nothing to do with Torch or PyTorch itself.

I think the revised instructions could be missleading.

EDIT: Oh, and also please remove the emote in the output (and also in the print statement). That’s something AI likes very much, but most terminals don’t show them either.
