我使用以下代码读取两个图像，设置它们的持续时间并将它们连接成一个动画。

from moviepy.editor import *

ic_1 = ImageClip('pg_0.png')
ic_1 = ic_1.set_duration(2.0)

ic_2 = ImageClip('pg_1.png')
ic_2 = ic_2.set_duration(2.0)

video = concatenate([ic_1, ic_2], method="compose")
video.write_videofile('test.avi', fps=24, codec='mpeg4')

它按预期工作pg_0.png和pg_1.png。但是如果我用另外两个图像替换这两个图像，我会收到一条错误消息：

ValueError: operands could not be broadcast together with shapes (272,363,3) (272,363)

如果需要更多详细信息，以下是完整消息：

为什么形状不一样？我使用的所有图像在我看来都是普通的 png 图像。我该如何解决这个问题？
