Converting a generic float64 index to Timestamp in Pandas

Converting a generic float64 index to Timestamp in Pandas

I think the issue was by ths following , Using today's date as the base, you can convert the floats to Timedelta values, interpreting the float values as seconds, and then adding that to today's date:
code :
In [15]: s2 = s.copy()

In [16]: s2.index = pd.Timestamp(datetime.date.today()) + pd.TimedeltaIndex(s.index, unit='s')

In [17]: s2

Hope that helps I want to change a dataframes' index (rows) from float64 to string or unicode. , You can do it that way:
code :
# for Python 2
df.index = df.index.map(unicode) 

# for Python 3 (the unicode type does not exist and is replaced by str)
df.index = df.index.map(str)

hope this fix your issue I think yous need [0] for convert DatetimeIndex as array with one value to scalar:
code :
triggerDate = dat.loc[dat.Close <= threshold[0]][:1].index[0]
triggerDate = dat.index[dat.Close <= threshold[0]][0]

To fix the issue you can do I have a column of date time strings in UTC which I need to convert to a viable datetime format in EST using pandas. I successfully converted the column, however I feel that my solution is long-winded and can be simplified, but I'm not sure how. Here is the way I'm currently converting the dates: , I will do tz_localize and tz_localize
code :
      dt.strftime('%Y-%m-%d %H:%M:%S')
0    2014-02-06 19:25:40
1    2014-02-06 19:25:41
2    2014-02-06 19:25:42
3    2014-02-06 19:25:42
4    2014-02-06 19:25:43
5    2014-02-06 19:25:43
6    2014-02-06 19:25:44

To fix the issue you can do I have a dataframe X_train to which i am concatenating a couple of another dataframe. This second & third dataframe is obtained from sparse matrix which has been been generated by a TF-IDF VEctorizer
code :
X_train_final = hstack( blocks=(x_tr_cwc_min,\

will help you This seems to be from the way that pandas is handling nans. When I set skipna=False in the sum method I get the numpy datatype
