error in AnomalyDetector instantiation
Opened this issue · 2 comments

I'm trying to run the Quick Start example, and in the very first command that instantiates a detector I get the following error:
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
The command run is
detector = anomaly_detector.AnomalyDetector(ts)
Could this be caused by a change in the Pandas library?
I installed the last version of luminol, 0.3.1, with pip and I'm using Python 2.7.11 from the Anaconda distribution version 4.1.0 on Kubuntu 15.10.
This is the full traceback of the error:
<class 'pandas.core.series.Series'>

Pretty sure Luminol is expecting a time series in the form of a dictionary of time values -> numeric values or a Luminol.TimeSeries object
Try converting to a dict

It seems to be working great when using a dict, thank you very much!
(I also created a numeric index instead of using the datetime one, in case it helps anyone.)
