在Python_Shelve_Pickle中保存会话的所有变量(工作空间)

Question

我正在尝试用python编写一个程序，它的工作方式几乎就像R's save一样。保存您的工作区的图像。以下是我的代码，但它运行不流畅，请帮助我使它工作

我使用了以下示例数据和一个图，以便可以在其上进行测试

Attempt1 -Using工具架，字典式的工作区节省

import shelve
import numpy as np
import matplotlib.pyplot as plt
import pickle
import os
import pandas as pd


x = np.arange(-3, 3, 0.01)
y = np.sin(np.pi*x)

fig = plt.figure()
ax = fig.add_subplot(111)
line=ax.plot(x, y)

#shelving or pickling my session

my_shelf = shelve.open('shelve.out','c') # 'n' for new
for name in dir():
    if not name.startswith (('__','_','In','Out','exit','quit','get_ipython')):
      try:
        my_shelf[name] = globals()[name] # I didn't undersatnd why to use globals()
      except Exception:
        pass
        print('ERROR shelving: {0}'.format(name))

my_shelf.close()

要恢复，请执行以下操作：

my_shelf = shelve.open('shelve.out','r')
for key in my_shelf:
    globals()[key]=my_shelf[key]

my_shelf.close()

这次用Pickle再试一次：

 with open('save.p', 'wb') as f:
     for name in dir():
         if not name.startswith (('__','_','In','Out','exit','quit','get_ipython')):
             try:
               pickle.dump(name, f)
             except Exception:
               print('ERROR shelving: {0}'.format(name))
               pass


 with open('save.p',"rb") as f:  # Python 3: open(..., 'rb')
    pickle.load(f)            

我将高度感谢任何帮助，道歉的任何错误缩进，同时粘贴到溢出他们得到的变化

dill模块提供了此功能。

dump_session(filename='/tmp/session.pkl'，main=None，byref=False，**kwds)

load_session(filename='/tmp/session.pkl'，main=None，**kwds)
