qml.workflow.set_shots

set_shots(device, shots)

Context manager to temporarily change the shots of a device.

Warning

set_shots is deprecated and will be removed in PennyLane version v0.40.

To dynamically update the shots on the workflow, shots can be manually set on a QNode call:

>>> circuit(shots=my_new_shots)

When working with the internal tapes, shots should be set on each tape.

>>> tape = qml.tape.QuantumScript([], [qml.sample()], shots=50)

This context manager can be used in two ways.

As a standard context manager:

>>> with qml.workflow.set_shots(dev, shots=100):
...     print(dev.shots)
100
>>> print(dev.shots)
None

Or as a decorator that acts on a function that uses the device:

>>> qml.workflow.set_shots(dev, shots=100)(lambda: dev.shots)()
100
