UnboundLocalError: local variable 'periodocity' referenced before assignment

[sr-ubuntu]

Hi,

A very interesting project, really appreciate it.
Got the below error while giving it a try, please help

<class 'pandas.core.frame.DataFrame'>
The data has been successfully parsed by infering a frequency, and establishing a 'Date' index and 'Target' column.

An insample split of training size 140 and testing size 47 has been constructed

I have experienced the same error when using sub-daily time series data such as hourly data etc. For example data with frequencies of the following: "3H", "5T" (minutes).

I didn’t see this issue and posted a new one this morning. I’m trying to use annual data (2007, 2008, etc) and I get the same error. I wonder if there is a way to specify the frequency and not have AtsPy infer it?
