I am working on a Cirq notebook and the quantum circuit is created in this way:

import cirq
import numpy as np

from cirq import GridQubit, Circuit

from cirq import Simulator
simulator = Simulator()

q = GridQubit(0,0)
circuit = Circuit.from_ops(
    cirq.measure(q, key='m')
)

and I receive an error:

AttributeError: type object 'Circuit' has no attribute 'from_ops'

What should I do to fix it?

from_ops was deprecated a long time ago. You can just call cirq.Circuit(*ops) like

import cirq
import numpy as np

from cirq import GridQubit, Circuit

from cirq import Simulator
simulator = Simulator()

q = GridQubit(0,0)
circuit = Circuit(
    cirq.measure(q, key='m')
)

instead.
