保存 matplotlib animation 时如何防止 IndexError？

Question

任何时候我 go 来保存我的 matplotlib animation 我都会收到以下错误消息：

X_points= Longs[0] IndexError: 列表索引超出范围

我本质上是在 map 上为散点图制作动画。 animation 无需保存即可完美运行，该错误仅在保存 animation 时出现。

import pandas as pd
import geopandas as gpd
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import contextily as cx
import matplotlib.animation as animation

plt.rcParams['animation.ffmpeg_path'] =r'C:\Users\Documents\In Progress\PythonMap\ffmpeg-2022-09-22-git-af919cf780-essentials_build\ffmpeg-2022-09-22-git-af919cf780-essentials_build\bin\ffmpeg.exe'
writer = animation.FFMpegFileWriter(fps=15, metadata=dict(artist='Me'), bitrate=1800)
SaveHere = r"C:\Users\Documents\In Progress\PythonMap\Test_Animation.mp4"

#Read the map
plotmap = r"path to my map"
truthplot = plt.imread(plotmap)

#Create subplot over the map
fig, ax = plt.subplots(figsize = (6,6),linewidth = 0.1, frameon=False)
plottitle = "Test"
ax.set_title(plottitle)
ax.set_xlabel("Longitude")
ax.set_ylabel("Latitude")
fig.tight_layout()

#Geodataframe boundaries
minx, miny, maxx, maxy = gdf.geometry.total_bounds

def animate(i):
    X_points= Longs[0]
    Y_points= Lats[0]
    Longs.remove(Longs[0])
    Lats.remove(Lats[0])
    ax.scatter(X_points, Y_points, zorder=1, alpha= 0.5, c='r', s=7)

#make the animation:
ani = FuncAnimation(fig, animate,frames = savecount,  interval=35, repeat = False)
ax.imshow(truthplot, extent = (minx, maxx, miny, maxy),aspect='auto')
plt.show()

# WORK ON SAVING THIS!!!!
ani.save(SaveHere, writer=writer,dpi=300)

任何朝着正确方向的帮助或步骤表示赞赏。 由于某种原因，它也只会在大约 20 分钟后给我错误。
