Webfor i in forecast_set: next_date = datetime.datetime.fromtimestamp(next_unix) next_unix += 86400 df.loc[next_date] = [np.nan for _ in range(len(df.columns)-1)]+[i] So here all we're doing is iterating through the forecast set, taking each forecast and day, and then setting those values in the dataframe (making the future "features" NaNs). WebX = np.array(df.drop(['label'], 1)) y = np.array(df['label']) Above, what we've done, is defined X (features), as our entire dataframe EXCEPT for the label column, converted to a numpy array. We do this using the .drop method that can be applied to dataframes, which returns a new dataframe. Next, we define our y variable, which is our label, as ...
