I'm using this simple code to test my Qiskit and learn how to use it but it keeps giving this problems, how do I fix it (Using VS Code and Anaconda Python 3.7)
import numpy as np
from qiskit import QuantumCircuit, ClassicalRegister, QuantumRegister
from qiskit import execute
# Create a Quantum Register with 3 qubits.Basicaly creating the number of qubits your system will use
q = QuantumRegister(3, 'q')
# Create a Quantum Circuit acting on the q register. Declaring the Circuit, this circuit shall create a GHZ state
circ = QuantumCircuit(q,)
# Add a H gate on qubit 0, putting this qubit in superposition.
circ.h(q[0])
# Add a CX (CNOT) gate on control qubit 0 and target qubit 1, putting
# the qubits in a Bell state.
circ.cx(q[0], q[1])
# Add a CX (CNOT) gate on control qubit 0 and target qubit 2, putting
# the qubits in a GHZ state.
circ.cx(q[0], q[2])
#Draws the circuit
from qiskit.tools.visualization import circuit_drawer
circuit_drawer(circ)
