    <div class="sphx-glr-thumbcontainer" tooltip="This example demonstrates how to load and save ONNX models that store tensor weights in separate external data files.  The approach allows the graph structure to be inspected independently of the (potentially very large) weight payload and enables memory-mapping the weight file directly when the model is loaded back through onnx_light.onnx.load.">
