# tosa-adapter-model-explorer — Adapter for ai-edge-model-explorer to support TOSA files

License: permissive · Maintenance: active · Downloads: 123.7K/mo

## What it is and what it does

This package is a plugin adapter that bridges TOSA model files and Google's Model Explorer visualization tool. TOSA is an open neural network exchange format from the ML Platform, and this adapter lets you load and inspect TOSA models graphically within Model Explorer's interface. It requires Python 3.10 or later and depends on ai-edge-model-explorer and flatbuffers at runtime.

You install it alongside Model Explorer, then launch Model Explorer with a command-line flag to enable the TOSA adapter. The package itself is maintained by Arm and is actively developed, though it remains in Beta status. It carries no known security vulnerabilities and uses a permissive Apache-2.0 license.

Use it for:

- Visualize and inspect TOSA neural network model graphs during development or debugging.
- Integrate TOSA model inspection into an ML workflow that already uses Model Explorer for other formats.
- Explore model structure and layer connectivity in TOSA files without writing custom parsing code.
- Verify model architecture and data flow in TOSA models before deployment on edge devices.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Enables visualization of TOSA neural network model files within the Model Explorer interface, acting as an adapter plugin for the ai-edge-model-explorer framework.

Yes, if you work with TOSA models and need visual inspection. The package is lightweight, actively maintained, carries no security issues, and uses a permissive license. The Beta status and small user base mean less real-world testing, so treat it as a solid but still-maturing tool. Requires Python 3.10+.

## Install

pip install tosa-adapter-model-explorer
uv add tosa-adapter-model-explorer
poetry add tosa-adapter-model-explorer

## Installing tosa-adapter-model-explorer

Before you install: Low friction install with a pure-Python wheel. Actively maintained as of the latest commit; however, the package is in Beta status and has a small user base, so edge cases may not be fully tested.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions; you must retain license and copyright notices in distributions.

Quickstart:

pip install tosa-adapter-model-explorer ai-edge-model-explorer==0.1.25
model-explorer --extensions=tosa_adapter_model_explorer

Requires Python >= 3.10 and < 3.13; torch must also be installed for Model Explorer to function.

Verify before relying:

- Whether the adapter works with all TOSA file versions and edge cases, given the Beta status and small adoption base.
- Performance characteristics when visualizing large or complex TOSA models in Model Explorer.
- Compatibility with Model Explorer versions beyond 0.1.25 mentioned in the usage example.
