遇到：Error loading "盘符:\***\Python310\lib\site-packages\torch\lib\c10_xpu.dll" or one of its dependencies.返回只安装intel的驱动：

完全清理已安装的

# 1. 先完全清理
pip uninstall torch torchvision torchaudio intel-extension-for-pytorch pytorch-triton-xpu -y

# 2. 删除残留文件
$pythonDir = "D:\Program Files\Python310"
$torchDirs = @(
"$pythonDir\Lib\site-packages\torch",
"$pythonDir\Lib\site-packages\torchvision",
"$pythonDir\Lib\site-packages\torchaudio",
"$pythonDir\Lib\site-packages\intel_extension_for_pytorch",
"$pythonDir\Lib\site-packages\pytorch_triton_xpu"
)

foreach ($dir in $torchDirs) {
if (Test-Path $dir) {
Remove-Item $dir -Recurse -Force -ErrorAction SilentlyContinue
Write-Host "删除: $dir" -ForegroundColor Yellow
}
}

# 3. 重新安装（先试 CPU 版本）
pip install torch==2.5.1 torchvision==0.20.1 torchaudio==2.5.1 --index-url https://download.pytorch.org/whl/cpu

# 4. 测试
python -c "import torch; print(f'PyTorch {torch.__version__} 安装成功'); print(f'可用设备: CPU')"
