# qiskit\_noise\_learning.models.get\_noise\_site

`qiskit_noise_learning.models.get_noise_site(model: LinearMap) → dict[str, str] | None`

[GitHub](https://github.com/Qiskit/qiskit-noise-learning/tree/stable/0.1/qiskit_noise_learning/models/utils.py)

The noise-site mapping of the map’s [`PauliLindbladModel`](/docs/api/qiskit-noise-learning/generated/models-pauli-lindblad-model "qiskit_noise_learning.models.PauliLindbladModel"), if it has exactly one.

**Parameters**

**model** – The map to inspect.

**Returns**

The `{gate_name: "before" | "after"}` mapping from the map’s single [`PauliLindbladModel`](/docs/api/qiskit-noise-learning/generated/models-pauli-lindblad-model "qiskit_noise_learning.models.PauliLindbladModel"), or `None` if `model` is, or contains, no (or more than one) [`PauliLindbladModel`](/docs/api/qiskit-noise-learning/generated/models-pauli-lindblad-model "qiskit_noise_learning.models.PauliLindbladModel").
