Python Data Frame resample on micro second

Question

I am working with resampling data frame and it works on hours, days mins, but doesn\'t resample less then sec. Program just hangs even on short time span. So am I missing someth

Answer 1

If I understand your problem correctly you can't resample microseconds to another frequency that is less than a second, right? I made a toy example and there doesn't seem to be a problem though:

import pandas as pd
import numpy as np

np.random.seed(0)
index=pd.date_range('22/10/2010', periods=100000, freq='U')
example=pd.Series(index=index,data=np.random.randn(100000))
example.resample('ms',how='sum')

This gives the expected output.

(I think your problem is that you are trying to resample data that are in a microsecond format to microseconds itself, which doesn't make any sense. You want to either upsample or downsample (as in my example).)
