Update: you can also pass datetime columns for offset-based rolling metrics with the on parameter (and, therefore, you do not have to have an index).

reset_index() to transform it into a single index dataframe (see here). set_index('time').įor MultiIndex, currently, you cannot use offsets. Follow this answer to receive notifications. Note : - For pandas python-dateutil, numpy, setuptools and pytz module required.
#How to install ipython, pandas window upgrade#
It is not clear from me whether the time information is a column in your dataframe or part of a MultiIndex. First upgrade pip version using command python -m pip install -upgrade pip after that just do pip install pandas. This is only valid for datetimelike indexes. Window will be a variable sized based on the observations included in If its an offset then this will be the time period of each window. This is the number of observations used forĬalculating the statistic. > 1478 raise ValueError("window must be an integer")ġ480 raise ValueError("window must be non-negative")Īs of today, the documentation states as follows:

ValueError Traceback (most recent call last) You probably want to pass int(new) instead.Įdit: as noted below, evidently the Pandas documentation is incomplete, and the real ultimate problem in this case is probably the lack of a time index, since creating a naive Dataframe and passing values like "10d" definitely raises the indicated error: In : df = pd.DataFrame() You are passing a string to df.rolling, but it expects only integer values.
