PyCharm没有显示Qiskit vizualization

Question

我无法从Qiskit获得一个直方图来显示使用PyCharm，即使我得到正确的数字。代码如下：

import numpy as np
from qiskit import QuantumCircuit, transpile
from qiskit.providers.aer import QasmSimulator
from qiskit.visualization import plot_histogram
from matplotlib import pyplot as plt

simulator = QasmSimulator()
circuit = QuantumCircuit(2, 2)
circuit.h(0)

# Add a CX (CNOT) gate on control qubit 0 and target qubit 1
circuit.cx(0, 1)

# Map the quantum measurement to the classical bits
circuit.measure([0,1], [0,1])
compiled_circuit = transpile(circuit, simulator)
job = simulator.run(compiled_circuit, shots=1000)
result = job.result()
counts = result.get_counts(compiled_circuit)
print("\nTotal count for 00 and 11 are:",counts)
plot_histogram(counts)

我应该得到这样的图像：

plot_histogram使用Matplotlib显示直方图。PyCharm提供了呈现科学模式下的矩阵库图的选项，只存在于PyCharm Professional中。
