WebExporting a model in PyTorch works via tracing or scripting. This tutorial will use as an example a model exported by tracing. To export a model, we call the torch.onnx.export() function. This will execute the model, recording a trace of what operators are used to compute the outputs. WebFeb 8, 2024 · Teams. Q&A for work.
