我试着用血小板()在python中启用更新图形:
import numpy as np
import numpy.matlib
import matplotlib.pyplot as plt
plt.ion()
plt.close('all')
tmax =30
W = np.random.rand(6,100)
fig, ax = plt.subplots(2,3)
plt.show()
for t in range (1, tmax):
W = t * W
for ii in range(2):
for jj in range(3):
output = W[3*ii+jj,:].reshape((10,10),order = 'F')
ax[ii,jj].clear()
ax[ii,jj].imshow(output, interpolation='nearest')
plt.tight_layout()
plt.draw()
plt.pause(0.1)
plt.waitforbuttonpress()
运行此操作将在控制台中显示空白数字并引发错误:

在ps.使用水蟒spyder
不能在控制台中使用interactive more(
ion
)。不幸的是,这个问题并不是很清楚您想要什么;但是让我们假设您想要显示一个窗口,其中包含动画的绘图。一个简单的方法是在IPython控制台外运行脚本。在spyder中,您可以进入Run/Configure(或按F6键),然后选择“Execute In a new dedicated Python console”。在现在脚本本身的问题是首先调用
plt.show()
,它显示空的子批。必须将其移除。在显示动画的版本将是
