制作病毒传播模拟的gif

desparer

如图，现在怎么制作gif？我用animation的但是报错了

import numpy as np
import matplotlib
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import random as r
class People():
    def __init__(self):
        self.x = r.randint(0,15)
        self.y = r.randint(0,15)
   # def move(self):
       # self.endx = self.x + r.choice(-1, 1)
       # self.endy = self.y + r.choice(-1, 1)
        #self.x = self.endx
       # self.y = self.endy
        
def update_points(num):
    '''
    更新数据点
    '''
    point_ani.set_data(mannumber[num].x + r.choice(-1, 1), mannumber[num].y + r. choice(-1, 1))
    return point_ani
fig = plt.figure(tight_layout=True)
plt.figure(num='图', figsize=(6, 4), dpi=120, facecolor='w', edgecolor='k')
plt.axis((-1, 16, -1, 16), 1)
mannumber = []
for i in range(0, 100):
    a = People()
    mannumber.append(a)
for i in range(0, 100):
    point_ani = plt.plot(mannumber[i].x, mannumber[i].y, 'bo')

ani = animation.FuncAnimation(fig, update_points, np.arange(0, 100), interval=100, blit=True)
ani.save('work/sin_testm.gif', writer='imagemagick', fps=10)

plt.show
