Code Sample, a copy-pastable example if possible

# On pandas 0.19.2, python 2.7

td30 = pd.timedelta_range('00:30:00', '01:30:00', freq='30T')
td30.to_series().to_pickle('C:/temp/td30.pkl')        

pd.read_pickle('c:/temp/td30.pkl')

Problem description

Objects with TimedeltaIndexes created under pandas 0.19.2 cannot be unpickled using pandas.read_pickle on later versions of pandas. I have found the same behavior on python 2.7 and 3.6, with pandas 0.20.3 through latest master. On Python 3.6 it raises ModuleNotFoundError: No module named 'pandas.indexes.base'; under python 2.7, it raises ImportError saying "No module named tdi".

Apologies if this is a dupe; while I have seen other reports of problems unpickling objects created in 0.19.2, it appears all could be fixed by using read_pickle, while here using read_pickle does not solve the problem.

Expected Output

Correct unpickling without error. Given the above example, should be the following under 0.23 master:

00:30:00 00:30:00
01:00:00 01:00:00
01:30:00 01:30:00
Freq: 30T, dtype: timedelta64[ns]

Pickle compat is at https://github.com/pandas-dev/pandas/blob/master/pandas/compat/pickle_compat.py

May be as simple as adding an item to

_class_locations_map = {
, or it may be harder :)

Thanks for the pointer @TomAugspurger. Looks like TimedeltaIndex was missing at 112 of pickle_compat.py. Adding it seems to fix the issue.

I'm also seeing issues with MultiIndexes with DatetimeIndex levels. I'll see if it's related and might combine into one PR.

Liam3851 commented Mar 1, 2018

@TomAugspurger TimedeltaIndex and Float64Index were missing from pickle_compat.py (the MultiIndex thing I saw before was actually with a Float64Index level, not the DatetimeIndex level). Adding them fixed the issue above and the other issue I found.

Happy to add a whatsnew, just wasn't sure which version this would target. Didn't add any tests because it doesn't appear any of the other index compat configs are being tested (unless I'm missing something), but I'm happy to put in a test for these if you think it's appropriate.
