Getting Started on Intel GPU — PyTorch 2.8 documentation

Created On: Jun 14, 2024 | Last Updated On: Jun 18, 2025

For Intel Data Center GPU

For Intel Client GPU

Intel GPUs support (Prototype) is ready from PyTorch* 2.5 for Intel® Client GPUs and Intel® Data Center GPU Max Series on both Linux and Windows, which brings Intel GPUs and the SYCL* software stack into the official PyTorch stack with consistent user experience to embrace more AI application scenarios.

To use PyTorch on Intel GPUs, you need to install the Intel GPUs driver first. For installation guide, visit Intel GPUs Driver Installation.

Please skip the Intel® Deep Learning Essentials installation section if you install from binaries. For building from source, please refer to PyTorch Installation Prerequisites for Intel GPUs for both Intel GPU Driver and Intel® Deep Learning Essentials Installation.

Now that we have Intel GPU Driver installed, use the following commands to install pytorch, torchvision, torchaudio.

For release wheels

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/xpu

For nightly wheels

pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/xpu

To check if your Intel GPU is available, you would typically use the following code:

import torch
print(torch.xpu.is_available())  # torch.xpu is the API for Intel GPU support

If the output is False, double check driver installation for Intel GPUs.

If you are migrating code from cuda, you would change references from cuda to xpu. For example:

# CUDA CODE
tensor = torch.tensor([1.0, 2.0]).to("cuda")

# CODE for Intel GPU
tensor = torch.tensor([1.0, 2.0]).to("xpu")

The following points outline the support and limitations for PyTorch with Intel GPU:

1. Both training and inference workflows are supported.

2. Both eager mode and torch.compile is supported. The feature torch.compile is also supported on Windows from PyTorch* 2.7 with Intel GPU, refer to How to Use Inductor on Windows with CPU/XPU.

3. Data types such as FP32, BF16, FP16, and Automatic Mixed Precision (AMP) are all supported.

This section contains usage examples for both inference and training workflows.

Here is a few inference workflow examples.

import torch
import torchvision.models as models

model = models.resnet50(weights="ResNet50_Weights.DEFAULT")
model.eval()
data = torch.rand(1, 3, 224, 224)

model = model.to("xpu")
data = data.to("xpu")

with torch.no_grad():
    model(data)

print("Execution finished")

import torch
import torchvision.models as models

model = models.resnet50(weights="ResNet50_Weights.DEFAULT")
model.eval()
data = torch.rand(1, 3, 224, 224)

model = model.to("xpu")
data = data.to("xpu")

with torch.no_grad():
    d = torch.rand(1, 3, 224, 224)
    d = d.to("xpu")
    # set dtype=torch.bfloat16 for BF16
    with torch.autocast(device_type="xpu", dtype=torch.float16, enabled=True):
        model(data)

print("Execution finished")

import torch
import torchvision.models as models
import time

model = models.resnet50(weights="ResNet50_Weights.DEFAULT")
model.eval()
data = torch.rand(1, 3, 224, 224)
ITERS = 10

model = model.to("xpu")
data = data.to("xpu")

for i in range(ITERS):
    start = time.time()
    with torch.no_grad():
        model(data)
        torch.xpu.synchronize()
    end = time.time()
    print(f"Inference time before torch.compile for iteration {i}: {(end-start)*1000} ms")

model = torch.compile(model)
for i in range(ITERS):
    start = time.time()
    with torch.no_grad():
        model(data)
        torch.xpu.synchronize()
    end = time.time()
    print(f"Inference time after torch.compile for iteration {i}: {(end-start)*1000} ms")

print("Execution finished")

Here is a few training workflow examples.

import torch
import torchvision

LR = 0.001
DOWNLOAD = True
DATA = "datasets/cifar10/"

transform = torchvision.transforms.Compose(
    [
        torchvision.transforms.Resize((224, 224)),
        torchvision.transforms.ToTensor(),
        torchvision.transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5)),
    ]
)
train_dataset = torchvision.datasets.CIFAR10(
    root=DATA,
    train=True,
    transform=transform,
    download=DOWNLOAD,
)
train_loader = torch.utils.data.DataLoader(dataset=train_dataset, batch_size=128)
train_len = len(train_loader)

model = torchvision.models.resnet50()
criterion = torch.nn.CrossEntropyLoss()
optimizer = torch.optim.SGD(model.parameters(), lr=LR, momentum=0.9)
model.train()
model = model.to("xpu")
criterion = criterion.to("xpu")

print(f"Initiating training")
for batch_idx, (data, target) in enumerate(train_loader):
    data = data.to("xpu")
    target = target.to("xpu")
    optimizer.zero_grad()
    output = model(data)
    loss = criterion(output, target)
    loss.backward()
    optimizer.step()
    if (batch_idx + 1) % 10 == 0:
         iteration_loss = loss.item()
         print(f"Iteration [{batch_idx+1}/{train_len}], Loss: {iteration_loss:.4f}")
torch.save(
    {
        "model_state_dict": model.state_dict(),
        "optimizer_state_dict": optimizer.state_dict(),
    },
    "checkpoint.pth",
)

print("Execution finished")

Note: Training with GradScaler requires hardware support for FP64. FP64 is not natively supported by the Intel® Arc™ A-Series Graphics. If you run your workloads on Intel® Arc™ A-Series Graphics, please disable GradScaler.
