2 non-Null rows limit in _prophet.py

[danielsioli]

Shouldn't line 246 in core/_prophet.py be
if len(self.input_df) - self.input_df.y.isnull().sum() < 2:

instead of
if len(self.input_df) - self.input_df.y.isnull().sum() <= 2:

?

That's the impression I get when reading the comment at 245:

If the input data frame contains less than 2 non-Null rows, prediction is not possible

Hello Daniel,
I am new to Qlik-python analytics and I'm trying to make forecasting but I keep getting the following as an error, do you have a solution to this?

""""

Forecast cannot be generated as the request contains less than two non-Null rows

Thanks
