NetronLink

Inline ONNX graph visualization inside VS Code and Cursor.

Open any .onnx file to explore the computational graph in an editor tab. Works locally and over Remote-SSH.

Requirements

• VS Code 1.90+ or Cursor
• Python 3.8+ available on the machine (or remote SSH host)

NetronLink creates a private virtual environment and installs its graph-viewer runtime automatically. No manual package install is required.

Usage

1. Install the extension.
2. Open a .onnx file — NetronLink becomes the default viewer.

On first use (or in the background after startup), the extension sets up its runtime. If setup failed silently earlier, opening a model retries and shows an error if it still cannot proceed.

To install or repair the runtime manually, run NetronLink: Install Runtime from the Command Palette. That command always deletes and recreates the managed virtual environment.

To open with the text editor instead, use Open With… and pick a text editor.

Settings

Remote / SSH

On Remote-SSH (and similar remote setups), the runtime is created on the remote machine. vscode.env.asExternalUri tunnels the UI to the local webview.

Privacy

Model files are processed locally on your machine (or remote host). Nothing is uploaded by this extension.
