2. 在 onnx 格式中,initializers 也算作模型的输入,不过不是 network 的输入,针对每一个 initializers,创建一个 Weights 对象,在 onnxpaser 的实现中,没有直接使用 tensorrt::Weights 对象,而是自己定义了一个ShapedWeights的类,这个类可以直接转成 tensorrt::Weights,以供 addxxxLayer api 使用。在构建 weights...
ONNX parser TensorRT 的 onnx parser 是一个独立的开源项目。 onnx-tensorrt:https://github.com/onnx/onnx-tensorrt 这里映射关系还是首先建立起来一个个映射函数,然后通过 op_type 来找到对应的映射函数。 typedef ValueOrStatus<std::vector<TensorOrWeights>> NodeImportResult; // 映射函数别名 typedef std...

▪ Definitions of standard data types. ▪ Definitions of built-in operators. ❑ Operator sets define the available built-in operators and their version (currently 6-12). ❑ The newest operator set supports around 160 operators. /onnx/onnx/blob/master/docs/IR.md /onnx/onnx/blob/...
TensorRT是Nvidia开发的一个神经网络前向推理加速的C++库,用户无需像剪枝那样在训练时对模型进行定制化处理,只需把模型提供给TensorRT即可实现加速。TensorRT支持多种模型的解析,包括:Tensorflow pb->uff->TensorRT, Pytorch pth-> onnx-> TensorRT等转换流程。
不同版本的 onnx operator 对算子的支持是不同的,而且即便是同样的算子,不同的版本其内部实现方式也可能会不同。不同版本的 TensorRT 对 onnx 的算子支持也不同,mxnet 对 onnx 算子支持可参见: ONNX Operator Coverage[6]。TensorRT 对 onnx 算子支持可参见:Supported ONNX Operators[7] 和 TensorRT-Support...

Supported ONNX Operators TensorRT 10.0 supports operators in the inclusive range of opset 9 to opset 20. Latest information of ONNX operators can be foundhere. More details and limitations are documented in the chart below. TensorRT supports the following ONNX data types: DOUBLE, FLOAT32, FLOAT...
TensorRT 10.6 GA Parser Update TensorRT 10.6 GA Release - 2024-11-5 For more details, see the10.6 GArelease notes Updated ONNX submodule version to 1.17.0 Fix issue where conditional layers were incorrectly being added Updated local function metadata to contain more information ...
TensorRT 10.0 includes tooling in the ONNX parser to identify unsupported nodes when the call to parse fails. This error reporting contains node name, node type, reason for failure, and the local function stack if the node is located in an ONNX local function. You can query the number...
