ONNX is an open format to represent deep learning models and enable interoperability between different frameworks.

ONNX

The Open Neural Network Exchange (ONNX) is an open-source artificial intelligence ecosystem. With ONNX, AI developers can more easily move models between state-of-the-art tools and choose the combination that is best for them. ONNX is widely supported and can be found in many frameworks, tools, and hardware. It is developed and supported by a community of partners.

"strip" onnx graph from its constants (initializers)

I have an onnx graph/model that has big constants in it, so it is taking a lot of time to load it and parse it. Can I "strip" the data from the graph, so I inspect the graph nodes without its data ?
