Overview
A visualization mechanism that converts ONNX model protobuf structures into human-readable text format for inspection and debugging.
Description
Model inspection converts the binary protobuf representation of an ONNX model into a human-readable textual form. The ONNX text format provides a concise representation of the model's structure including graph topology, operator types, tensor shapes, and attributes. This is essential for debugging model construction, verifying transformations, and understanding model structure without requiring specialized visualization tools.
The text format is designed to be both readable by humans and parseable by machines, enabling round-trip conversion between text and protobuf representations.
Usage
Use this principle when you need to visually inspect a model's structure, debug graph construction issues, verify the results of transformations (such as shape inference, version conversion, or composition), or generate human-readable documentation of a model's architecture.
Theoretical Basis
Model inspection is a serialization to a human-readable format:
Failed to parse (syntax error): {\displaystyle \text{to\_text}: \text{ModelProto} \rightarrow \text{String} }
The text representation preserves the complete model structure:
- Graph inputs/outputs with types and shapes
- Node operations with their inputs, outputs, and attributes
- Initializer declarations
- Opset import declarations
