从matplotlib中Pickle图形:2

下列的 Pickle figures from matplotlib ,我正试图从泡菜中装入一个人物。我使用的代码与响应中建议的修改相同。 正在保存脚本:

import numpy as np
import matplotlib.pyplot as plt
import pickle as pl

# Plot simple sinus function
fig_handle = plt.figure()
x = np.linspace(0,2*np.pi)
y = np.sin(x)
plt.plot(x,y)
# plt.show()

# Save figure handle to disk
pl.dump(fig_handle,file('sinus.pickle','wb'))

正在加载脚本:

import matplotlib.pyplot as plt
import pickle as pl
import numpy as np

# Load figure from disk and display
fig_handle = pl.load(open('sinus.pickle', 'rb'))
fig_handle.show()

保存脚本会生成一个名为“sinus.pickle”的文件,但加载的文件不会显示预期的数字。有什么建议吗?

Python 2.7.13 matplotlib 2.0.0 numpy 1.12.1

p、 根据建议,美国更换了fig\U手柄。用pat显示()。show()产生错误: 回溯(最近一次呼叫最后一次):
