【问题描述】:
我尝试使用matplotlib.pyplot 和matplotlib.animation 创建动画,但遇到了两个问题:
- 第一个是,我去了matplotlib animation page,然后我尝试了他们的代码:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig = plt.figure()
def f(x, y):
return np.sin(x) + np.cos(y)
x = np.linspace(0, 2 * np.pi, 120)
y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)
# ims is a list of lists, each row is a list of artists to draw in the
# current frame; here we are just animating one artist, the image, in
# each frame
ims = []
for i in range(60):
x += np.pi / 15.
y += np.pi / 20.
im = plt.imshow(f(x, y), animated=True)
ims.append([im])
ani = animation.ArtistAnimation(fig, ims, interval=50, blit=True,
repeat_delay=1000)
# ani.save('dynamic_images.mp4')
plt.show()
我得到一个错误:AttributeError: 'function' has no attribute 'canvas' (我重新尝试了,我没有得到任何错误......
- 2nd,当我取消注释
ani.save('dynamic_images.mp4')时,我收到此错误:TypeError: 'MovieWriterRegistry' object is not an iterator。这个更让我困扰。如果您对最后一个问题有任何解决方案,请现在告诉我。
