Question

我想创建2个动画并将它们保存到一个文件中，但是会收到错误消息： TypeError：＆＃39; FuncAnimation＆＃39;对象不可迭代

另外每个动画都运行良好。

这是一个演示问题的最小例子。像ax.text和ax.axhline这样的化妆品可能有助于展示我尝试做的事情，但对问题并不重要。我在Jupyter笔记本中运行代码。

感谢您的帮助。

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import animation

xdata = np.array([0.2, 0.4, 0.6, 0.8])
ydata = np.array([0, 0, 0, 0])

fig = plt.figure(figsize=(8,1.25))
ax = fig.add_subplot(111)
ax.set_xlim(0, 1)
ax.set_ylim(-0.5, 0.5)
ax.barh(0, 1, align='center', height=0.7, color='.95', ec='None', zorder=-20)
ax.axhline(0, 0, 1, color='0.25', linewidth=.5)
ax.text(0, -0.45, "0", verticalalignment = "center", horizontalalignment="center", fontsize=10)
ax.text(1, -0.45, "1", verticalalignment = "center", horizontalalignment="center", fontsize=10)
ax.text(-0.01, 0, "0", verticalalignment = "center", horizontalalignment="center", fontsize=10)
ax.text(0.75, -0.45, "3/4", verticalalignment = "center", horizontalalignment="center", fontsize=10)
ax.axvline(0.75, 0.15, 0.85, color='.5', linestyle='dotted', linewidth=0.75)

line, = ax.plot(xdata, ydata, 'ro', markersize=7)

def init0():     # initialization function for first animation
    line.set_data(xdata, ydata)
    return line,

def init1():     # second animation
    ax.set_xlim(0.5, 1)
    ax.text(0.5, -0.45, "1/2", verticalalignment = "center", horizontalalignment="center", fontsize=10)
    line.set_data(xdata, ydata)
    return line,

def animate(i):     # update function
    ax.figure.canvas.draw()
    return line,

# call animators
anim0 = animation.FuncAnimation(fig, animate, init_func=init0, frames=150, interval=20, blit=True)
anim1 = animation.FuncAnimation(fig, animate, init_func=init1, frames=150, interval=20, blit=True)


fig.set_size_inches(16, 2.5, True)     # improve resolution in animation
plt.axis('off')

anim0.save('anims.mp4', fps=30, extra_args=['-vcodec', 'libx264'], extra_anim=anim1)
plt.show()

FuncAnimation不可迭代
