Description
Runing the code as is below results in a segmentation fault when it gets to resample()
The first pass runs, and then either the 2nd or 3rd run produces:
Segmentation fault: 11
It happens on:
- Python 2.7.9 and Pandas 0.16.1
- Python 3.4.3 and Pandas 0.16.1
It does not happen on:
- Python 2.7.9 with Pandas 0.12.0
Those are the only ones I've tested
import pandas as pd
frame = pd.DataFrame({'delay_category': {pd.Timestamp('2014-05-18 08:50:00'): 'yes',
pd.Timestamp('2014-05-19 14:35:00'): 'yes',
pd.Timestamp('2014-05-22 08:45:00'): 'yes',
pd.Timestamp('2014-05-27 10:00:00'): 'no',
pd.Timestamp('2014-05-28 11:05:00'): 'no'}})
frame_filter = frame[frame['delay_category'] == 'da']['delay_category']
for i in range(1,10):
frame_filter.resample('d', how='count')
Setting how=sum also does not result in the issue.
It only happens after the frame has been selected with a parameter that doesn't work, resulting in an empty series.
Eg. this works fine:
frame_filter = frame[frame['delay_category'] == 'yes']['delay_category']
for i in range(1,10):
frame_filter.resample('d', how='count')
