保存 gif 文件 Python

Question

我正在尝试使用以下代码片段保存动画：

import matplotlib.animation as animation 
import matplotlib.pyplot as plt 

import copy

......
frames = []

for i in range(500):
    config_copy = copy.deepcopy(config)
    frames.append((plt.imshow(config_copy, cmap='Greys_r', aspect=1,
         interpolation='none', vmin=-1, vmax=1), plt.scatter(loc[1], loc[0], c='red', marker='o', s=50)))
...
animation = FuncAnimation(f, lambda x: x, frames=frames, blit=True, interval=200)
animation.save('fun_animation_random_direction.gif', writer='imagemagick', fps=30)
plt.show()

当我运行代码时，动画会按预期显示！但是当我打开生成的 gif 文件时，我只看到一张似乎同时显示所有帧的图片。我该如何解决这个问题？

我尝试使用 Windows 照片查看器以外的其他应用程序打开 gif 文件，但没有成功...

    import matplotlib.animation as animation 
import matplotlib.pyplot as plt 
import copy

# Assuming config and loc are defined and updated within the loop

frames = []

for i in range(500):
    # Assuming config and loc are updated within the loop
    config_copy = copy.deepcopy(config)  # Assuming config is updated in each iteration
    frames.append((plt.imshow(config_copy, cmap='Greys_r', aspect=1,
                    interpolation='none', vmin=-1, vmax=1), 
                    plt.scatter(loc[1], loc[0], c='red', marker='o', s=50)))

# Check if frames are correctly collected and if they represent the changes over time

# Show the animation before saving
fig, ax = plt.subplots()
ani = animation.ArtistAnimation(fig, frames, interval=200, blit=True)
plt.show()

# Save the animation using different parameters or writers
ani.save('fun_animation_random_direction.gif', writer='imagemagick', fps=30)
