使用to_hdf将熊猫数据帧保存到磁盘时出现分段错误

Question

I am trying to save a dataframe to disk using hdf5 format. Even this simple piece of code gives me "Segmentation fault (core dumped)"

import pandas as pd
import tables

df=pd.DataFrame([0,1,2,3],index=['a','b','c','d'])

df.to_hdf('test.h5','test',mode='w',format='table')

The problem seems to be the table-format. In fixed-mode it runs fine. I tried python 2.7.11+ and 3.5.1+ and am running pandas 0.18.1. Any ideas what I am doing wrong?

Answer 1

Use a newer version of PyTables. Version 3.2.3.1 does the job perfectly.
