Question

我试图保存数据帧以供以后在pandas中使用。但是，我有以下错误。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/source/Linux/pkg/python-2.7.3/lib/python2.7/site-packages/pandas-0.11.0-py2.7-linux-x86_64.egg/pandas/core/series.py", line 2881, in to_csv

    formatter.save()

    f.close()
IOError: [Errno 5] Input/output error

即使是简单的对象dataframe.save，

a = DataFrame({'a':[1,3,4],'b':[3,4,5]})也会失败。

不推荐使用select * from config where name='sugar_version'; +----------+---------------+-------+ | category | name | value | +----------+---------------+-------+ | info | sugar_version | 6.4.5 | +----------+---------------+-------+ 1 row in set (0.00 sec) cat config.php |grep sugar_version 'sugar_version' => '6.4.5',方法。您应该save代替我们。看起来你正在使用pandas 0.11，它已经很老了。最新版本是0.16。您还可以考虑将其保存到csv或HDF5。 http://pandas.pydata.org/pandas-docs/stable/io.html

IOE错误使用dataframe.to_csv和dataframe.save将数据写入文件
