#pickle Python

本文记录了一次使用Python的pickle模块加载数据时遇到的问题及解决过程。错误原因是尝试加载的数据文件格式不正确，导致无法正常解析。通过更改数据文件的格式设置解决了问题。

在terminal输入python后，执行命令报错：

import numpy
import pickle
import numpy.core.multiarray
data = pickle.load(open('Workspace/Ch5_Py_Mrjob_PegasosSVM/svmDat27','rb'))

报错：
Traceback (most recent call last):
File “”, line 1, in
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 1384, in load
return Unpickler(file).load()
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 864, in load
dispatchkey
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 1096, in load_global
klass = self.find_class(module, name)
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 1130, in find_class
import(module)
ImportError: No module named multiarray

data = pickle.load(open('Workspace/Ch5_Py_Mrjob_PegasosSVM/svmDat27','r'))

 data = pickle.load(open('Workspace/Ch5_Py_Mrjob_PegasosSVM/svmDat27'))

继续报错：
Traceback (most recent call last):
File “”, line 1, in
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 1384, in load
return Unpickler(file).load()
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 864, in load

klass = self.find_class(module, name)
File “/home/hduser/anaconda2/lib/python2.7/pickle.py”, line 1130, in find_class
import(module)
ImportError: No module named multiarray

补充解决方案来了

并不是代码本身的编码有问题，是数据存储格式有问题1！！！1解决方法：vim 进入数据文件，:set ff=unix
