Python 如何在动画结束后继续计算而不关闭图形窗口

我有6个IMU传感器。我可以从Python中读取它们。我想用传感器读数做一些人体姿势的动画。动画需要处于

while（True）

循环中。所以我的问题是：

我实现了如下动画功能：

# import necessary packages
import numpy as np
from numpy import pi, sin, cos, sqrt
import matplotlib.pyplot as plt
import matplotlib.animation as animation

# input parameters
r = 1.0  # crank radius
l = 4.0  # connecting rod length
rot_num = 1  # number of crank rotations
increment = 0.1  # angle increment

# create the angle array, where the last angle is the number of rotations*2*pi
angles = np.arange(0, rot_num * 2 * pi + increment, increment)

X1 = np.zeros(len(angles))  # array of crank x-positions: Point 1
Y1 = np.zeros(len(angles))  # array of crank y-positions: Point 1
X2 = np.zeros(len(angles))  # array of rod x-positions: Point 2
Y2 = np.zeros(len(angles))  # array of rod y-positions: Point 2

# find the crank and connecting rod positions for each angle
for index, theta in enumerate(angles, start=0):
    x1 = r * cos(theta)  # x-cooridnate of the crank: Point 1
    y1 = r * sin(theta)  # y-cooridnate of the crank: Point 1
    x2 = 0  # x-coordinate of the rod: Point 2
    # y-coordinate of the rod: Point 2
    y2 = r * sin(theta) + sqrt(l ** 2 - (r * cos(theta)) ** 2)

    X1[index] = x1  # crankshaft x-position
    Y1[index] = y1  # crankshaft y-position
    X2[index] = x2  # connecting rod x-position
    Y2[index] = y2  # connecting rod y-position

# set up the figure and subplot
fig = plt.figure()
fig.canvas.set_window_title('Matplotlib Animation')
ax = fig.add_subplot(111, aspect='equal', autoscale_on=False, xlim=(-4, 4), ylim=(-2, 6))
ax.grid()
ax.set_title('Piston Motion Animation')
ax.axes.xaxis.set_ticklabels([])
ax.axes.yaxis.set_ticklabels([])
line, = ax.plot([], [], 'o-', lw=5, color='#de2d26')

plt.ion()
plt.show()
# initialization function
def init():
    line.set_data([], [])
    return line,


# animation function
def animate1(i):
    x_points = [0, X1[i], X2[i]]
    y_points = [0, Y1[i], Y2[i]]

    line.set_data(x_points, y_points)
    return line,


def animate2(i):
    x_points = [0, X1[i], X2[i]]
    y_points = [0, Y1[i], Y2[i]]

    line.set_data(x_points, y_points)
    return line,


# call the animation
ani1 = animation.FuncAnimation(fig, animate1, init_func=init, frames=len(X1), interval=40, blit=True, repeat=False)

plt.draw()
plt.pause(0.001)

# to save animation, uncomment the line below:
# ani.save('offset_piston_motion_animation.mp4', fps=30, extra_args=['-vcodec', 'libx264'])

# show the animation
print('Continue')
plt.show()

它会导致程序冻结。因为我需要调用动画，然后返回到循环的开始并重复计算，当然还要再次设置人体姿势的动画，所以当我到达动画命令时，我需要以某种方式继续编程计算。在线找到的当前解决方案（写在代码中）将关闭动画打印窗口以继续，但我需要保持动画打印窗口打开，因为下一个动画应该从最后一个姿势开始。我不知道如何做到这一点。我放在这里的代码是一个示例动画

ani1 = animation.FuncAnimation(fig, animate1, init_func=init, 
frames=len(X1), interval=40, blit=True, repeat=False)
