JupyterLab在使用魔术命令 %matplotlib tk 开启单独窗口显示图形后运行绘图代码报错，这个怎么解决？

源代码如下

import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt

# 解决中文显示问题
mpl.rcParams['font.sans-serif'] = ['SimHei']
mpl.rcParams['axes.unicode_minus'] = False

# 设置在jupyter中matplotlib的显示情况
%matplotlib tk

# 一维原始图像
def f1(x):
    return 0.5 * (x - 0.25) ** 2

# 构建数据
X = np.arange(-4, 4.5, 0.05)
Y = np.array(list(map(lambda t: f1(t), X)))

# 画图
plt.figure(facecolor='w')
plt.plot(X, Y, 'r-', linewidth=2)
plt.title(u'函数$y=0.5 * (θ - 0.25)^2$')
plt.show()

执行后，出现卡死的窗口
tk窗口卡死
后台报如下错误

ERROR:tornado.application:Exception in callback functools.partial(<function Kernel.enter_eventloop.<locals>.advance_eventloop at 0x0000020531BB56A8>)

刚运行了没问题啊
