分段错误:pandas to_csv操作期间为11 [英] Segmentation fault: 11 during pandas to_csv operation

问题描述

我正在使用Python 2.7 virtualenv和通过pip安装的熊猫在Mac OS 10.10.5上工作.

I'm working on Mac OS 10.10.5, using a Python 2.7 virtualenv and pandas installed via pip.

我有一个Pandas dataFrame(称为"pivot")，它是13843行乘40列.大多数数据单元都是单个字符(A，B，C或D).

I have a Pandas dataFrame (called 'pivot') which is 13843 rows by 40 columns. Most of the data cells are single characters (A, B, C or D).

我正在尝试使用以下命令将其导出到csv文件:

I am trying to export this to a csv file using the command:

pivot.to_csv(path_or_buf="test.csv",sep=",", encoding='utf-8')

输出CSV到达第8743行，该行在第8列之后被截断，并且该程序因分段错误而崩溃:11

The output CSV gets to row 8743, which is truncated after the 8th column, and the program crashes out with a Segmentation fault: 11

这不应该是内存问题，因为我的Mac具有16Gb RAM.

It shouldn't be a memory problem, as my Mac has 16Gb RAM.

有什么想法吗?

谢谢

推荐答案

原来是数据问题.在某些情况下，我尝试透视重复的数据行.

Turned out to be an issue with the data. There were instances where I was trying to pivot duplicate data rows.
