cirq.devices.GridDeviceMetadata(
    qubit_pairs: Iterable[Tuple['cirq.Qid', 'cirq.Qid']],
    gateset: 'cirq.Gateset',
    gate_durations: Optional[Dict['cirq.GateFamily', 'cirq.Duration']] = None,
    all_qubits: Optional[Iterable['cirq.Qid']] = None
)

Args
qubit_pairs	Iterable of pairs of cirq.Qids representing bi-directional couplings.
gateset	cirq.Gateset indicating gates supported everywhere on the device.
gate_durations	Optional dictionary of cirq.GateFamily instances mapping to cirq.Duration instances for gate timing metadata information. If provided, must match all entries in gateset.
all_qubits	Optional iterable specifying all qubits found on the device. If None, all_qubits will be inferred from the entries in qubit_pairs.

Raises
ValueError	if the union of GateFamily keys in gate_durations is not identical to set of gate families in gateset.
ValueError	If qubit_pairs contains a self loop.
ValueError	if all_qubits is provided and is not a superset of all the qubits found in qubit_pairs.

Attributes
gate_durations	Get a dictionary mapping from gateset to duration for gates.
gateset	Returns the cirq.Gateset of supported gates on this device.
isolated_qubits	Returns the set of all isolated qubits on the device (if appliable).
nx_graph	Returns a nx.Graph where nodes are qubits and edges are couple-able qubits.
qubit_pairs	Returns the set of all couple-able qubits on the device.
qubit_set	Returns the set of qubits on the device.
