大lao，这个为啥出不来图像啊#python

Question

import pyaudio
import struct
import numpy as np
import matplotlib.pyplot as plt
CHUNK = 1024 * 4
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
p = pyaudio.PyAudio()
stream = p.open(
format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
output=True,
frames_per_buffer=CHUNK
)

fig, ax = plt.subplots()

x = np.arange(0, 2 * CHUNK, 2)
line, = ax.plot(x, np.random.rand(CHUNK))
ax.set_ylim(0, 255)
ax.set_xlim(0, CHUNK)

while True:
data = stream.read(CHUNK)
data_int = np.array(struct.unpack(str(2 * CHUNK) + 'B', data), dtype='b')[::2] + 127
line.set_ydata(data_int)
fig.canvas.draw()
fig.canvas.flush_events()

建议使用代码插入功能重新写一遍问题，markdown会吞格式
