# profiling-debugging
Use this sub-skill when the user asks about ExecuTorch profiling, ETDump, ETRecord, Inspector, delegate debugging, model visualization, memory-planning inspection, intermediate outputs, or runtime/export accuracy/performance triage.
## Route Here For
- Enabling and collecting ETDump at runtime.
- Generating ETRecord during export and using it to map runtime events to graph/source/module hierarchy.
- Loading artifacts with `executorch.devtools.Inspector`.
- Comparing delegate and CPU outputs, inspecting numerical divergence, and deciding when to route QNN-specific per-layer debugging to `../qualcomm/SKILL.md`.
- Understanding memory planning and visualization artifacts.
## Fast Path
1. Ask which artifacts the user already has: `.pte`, ETRecord, ETDump, debug buffer, eager reference outputs, backend logs.
2. If no ETRecord exists and source model/export is available, regenerate export with ETRecord enabled before collecting runtime data.
3. If only ETDump exists, perform raw timing inspection but explain that source/module attribution may be limited.
4. Use [profiling workflows](references/profiling-workflows.md) and [API reference](references/api-reference.md).
5. For artifact sanity checks, run:
```bash
python scripts/inspect_etdump_summary.py --etdump path/to/run.etdp --etrecord path/to/model.etrecord
```
The helper checks file presence and Inspector import availability; it does not parse private model data unless the installed package supports it.
