Why Amazon Forecast cannot train the predictor?
问题 While training my predictor I came across this error and I got stuck how to fix it. I have two data-series, a "Target time-series data" with 9234 rows and a single "item_id" and a second one that is "Related time-series data" with the same number of rows as I only have a single id. I'm setting de data with a window of 180 days, what is exactly the difference between the second and the first number that has appeared on the error, 9414 - 9234 = 180. We were unable to train your predictor.
