Adapter for Model Explorer to support PTE files for Ethos-U and VGF targets
Decision gist · record as of 2026-08-14
Yes, if you work with PyTorch Executorch models targeting Arm or XNNPACK backends and need to visualize or debug them. The package is actively maintained, has low install friction, carries a permissive license, and integrates cleanly into Model Explorer. The Beta status and small user base suggest it is specialized rather than production-hardened, so verify it supports your specific backend before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.10, <3.13.
- ai-edge-model-explorer must be installed separately.
- Low friction install with a pure-Python wheel.

What it is and what it does
This package is a plugin for Model Explorer that adds support for visualizing PyTorch Executorch PTE files. It integrates with Model Explorer's extension system to enable inspection and debugging of neural network models compiled for specific hardware targets: Arm Ethos-U NPU, Arm VGF, and XNNPACK backends.
You install it alongside ai-edge-model-explorer and activate it via a command-line flag. Once enabled, it allows you to load and inspect PTE files in Model Explorer's graphical interface, making it useful for developers working with Executorch models on Arm hardware or XNNPACK targets. The package depends on ai-edge-model-explorer, vgf-adapter-model-explorer, tosa-adapter-model-explorer, and flatbuffers, and runs on Linux, macOS, and Windows.
Use it for
- Visualize and debug Executorch models compiled for Arm Ethos-U NPU deployment.
- Inspect model graphs and operations for Arm VGF backend targets.
- Analyze XNNPACK-compiled models in a graphical interface.
- Verify model structure and layer connectivity before deploying to edge devices.
- Troubleshoot model compilation issues by examining the resulting PTE file structure.
