# ONNX023: external-tensor-outside-model-dir

**Code:** `ONNX023`

**Name:** `external-tensor-outside-model-dir`

**Severity:** error

**Category:** spec

**Target:** value

**Fixable:** No

## Message

## Suggestion

Move the tensor data file inside the model directory.

## Details

External tensor paths must not escape the model's directory (e.g.
using "../"). This ensures the model is self-contained and portable.
