alanxinn.TensorRtOnnxBuilder

C# 调用 TensorRT native builder，将 ONNX 转为 serialized engine。 不启动 trtexec.exe。

安装

dotnet add package alanxinn.TensorRtOnnxBuilder --version 0.1.3

要求 Windows x64、NVIDIA 驱动和匹配的 TensorRT/CUDA。 NuGet 仅包含 C# 程序集和 builder DLL。

C# 示例

using alanxinn.TensorRt;

var result = TensorRtOnnxBuilder.Build(
    "model.onnx",
    "model.engine",
    new TensorRtBuildOptions
    {
        Precision = TensorRtPrecision.Fp32,
        WorkspaceMiB = 4096,
        EnableTf32 = true
    });

动态输入

var profile = new TensorRtOptimizationProfile
{
    MinShapes = new() { ["images"] = new TensorRtShape(1, 3, 320, 320) },
    OptShapes = new() { ["images"] = new TensorRtShape(1, 3, 640, 640) },
    MaxShapes = new() { ["images"] = new TensorRtShape(1, 3, 1280, 1280) }
};

动态输入的每个输入都必须同时出现在 min/opt/max 中。 INT8 适用于包含 Q/DQ 节点的 ONNX。

TensorRT 8.6 解析原始 YOLO26 ONNX 可能在 ReduceMax/TopK 失败； 请先使用修正版 ONNX，或升级 TensorRT。

Runtime

缺少 runtime 时默认下载并缓存到：

%LOCALAPPDATA%\alanxinn\TensorRtOnnxBuilder\0.1.3\win-x64

可配置：

TensorRtRuntime.DownloadUrl = "...";
TensorRtRuntime.CacheDirectory = @"D:\TensorRT\runtime";
TensorRtRuntime.ExpectedSha256 = "...";
TensorRtRuntime.DisableAutoDownload = true;

构建

cmake --preset ninja-msvc-release
cmake --build --preset build-ninja-msvc-release
dotnet pack .\csharp\alanxinn.TensorRtOnnxBuilder\alanxinn.TensorRtOnnxBuilder.csproj -c Release
