在Python中使用cPickle导入错误

Question

I am using Pickle in Python2.7. I am getting error while using cPickle.load() method. The code and error is shown below. Can someone guide me through this?

Code:

#! usr/bin/python
import cPickle
fo = open('result','rb')
dict1 = cPickle.load(fo)

Error:

Traceback (most recent call last):
File "C:\Python27\test.py", line 7, in <module>
dicts = cPickle.load(fo)
ImportError: No module named options

Answer 1

It seems like you can not do

import options

but when you or someone else did

cpickle.dump(xxx, open('result', 'rb'))

there was an object with a class or function of a module options that existed at this point in time, in xxx .

Solution

1. You can open the file binarily and replace options with the module you replaced the old module options with.

2. You probably created the file in your package like in module package.main by executing the file main.py or something like it, having a module options in the same directory. Now you do import package.main , try to read the file and options is now called package.options and the module options can not be found.

3. How did you create this file? How do you load it now? cPickle/pickle does not transfer source code - so if you use a function you need the module when you load it.
