在PyTorch中,我们可以使用torch.onnx.register_custom_op_symbolic函数来注册自定义操作符的转换规则。下面是一个示例: importtorchimporttorch.onnxdefcustom_op_symbolic(g,input):# Define custom symbolic function herereturng.op("CustomOp",input)torch.onnx.register_custom_op_symbolic("custom_op",custom_op...
【GiantPandaCV导语】本文基于Pytorch导出的ONNX模型对TVM前端进行了详细的解析,具体解答了TVM是如何将ONNX模型转换为Relay IR的,最后还给出了一个新增自定义OP的示例。其实在TVM中支持编译多种目前主流的深度学习框架如TensorFlow,Pytorch,MxNet等,其实它们的前端交互过程和本文介绍的ONNX也大同小异,希望对TVM感兴趣的...

onnx规范目前有两个变体,主要区别在与支持的类型和默认的operator集合。onnx神经网络变体只使用tensor作为输入和输出,而作为支持传统机器学习模型的onnx-ml,还可以识别sequence和map,onnx-ml为支持非神经网络算法扩展了onnx operator集合,本文只关注onnx神经网络这个变体。 二、ONNX模型结构 ONNX的模型结构定义位于http...
