动画未在Jupiter notebook中运行

Question

我有一些在Spyder中运行的代码，但是当我尝试在Jupiter notebook中运行它时，它不起作用(我尝试将%matplot lib放在单元格的顶部，但只得到了以下错误: AttributeError：'NoneType‘对象没有’lower‘属性)这是代码：

import numpy as np
from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import animation
def randrange(n, vmin, vmax):
   return (vmax - vmin) * np.random.rand(n) + vmin
n = 100
xx = randrange(n, 23, 32)
yy = randrange(n, 0, 100)
zz = randrange(n, -50, -25)
fig = plt.figure()
ax = Axes3D(fig)


def init():
    ax.scatter(xx, yy, zz, marker='o', s=20, c="goldenrod", alpha=0.6)
    return fig,

def animate(i):
    ax.view_init(elev=10., azim=i)
    return fig,

# Animate
anim = animation.FuncAnimation(fig, animate, init_func=init,
                               frames=360, interval=20, blit=True)

有什么想法吗？

Jupiter环境不具备渲染动画的能力，因此它似乎使用了HTML视频功能。我是jupyterLab，我总是带着这个运行。

import numpy as np
from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import animation
from IPython.display import HTML # updated

def randrange(n, vmin, vmax):
    return (vmax - vmin) * np.random.rand(n) + vmin

n = 100
xx = randrange(n, 23, 32)
yy = randrange(n, 0, 100)
zz = randrange(n, -50, -25)
fig = plt.figure()
ax = Axes3D(fig)


def init():
    ax.scatter(xx, yy, zz, marker='o', s=20, c="goldenrod", alpha=0.6)
    return fig,

def animate(i):
    ax.view_init(elev=10., azim=i)
    return fig,

# Animate
anim = animation.FuncAnimation(fig, animate, init_func=init,
                               frames=360, interval=20, blit=True)

plt.close() # updated
HTML(anim.to_html5_video()) # updated
