腌制一个DataFrame [英] Pickling a DataFrame

问题描述

我正在尝试用...腌制一个DataFrame

I am trying to pickle a DataFrame with

import pandas as pd
from pandas import DataFrame
data = pd.read_table('Purchases.tsv',index_col='coreuserid')
data.to_pickle('Purchases.pkl')

我已经在数据"上运行了一段时间，没有任何问题，所以我知道这不是数据损坏问题.我正在考虑可能的语法，但是我尝试了多种变体.我犹豫要给出整个错误消息，但它的结尾是:

I have been running on "data" for a while and have had no issues so I know it is not a data corruption issue. I am thinking likely syntax but I have tried a number of variants. I hesitate to give the whole error message but it ends with:

\pickle.pyc in to_pickle(obj, path)
 13     """
 14     with open(path, 'wb') as f:
 15         pkl.dump(obj, f, protocol=pkl.HIGHEST_PROTOCOL)

 SystemError: error return without exception set 

创建了Purchases.pkl文件，但如果我打电话

The Purchases.pkl file is created but if I call

data = pd.read_pickle('Purchases.pkl')

我收到EOFError.我正在使用Canopy 1.4，所以熊猫0.13.1应该足够新，才能具有此功能.

I get EOFError. I am using Canopy 1.4 so pandas 0.13.1 which should be recent enough to have this functionality.

推荐答案

快进几年了，现在工作正常.谢谢熊猫;)

Fast forward a few years, and now it works fine. Thanks pandas ;)
