Hi, I was using Fine tuning option in TimeGPT on a monthly data set. I was getting this error that each unique time series should have atleast 36 months data.. But in reality, very often we find time series with less than 3 years/36 months history. How to navigate through it? Any work around? Like, if i have 1000 time series in total & if 700 have >= 36 months, i can fine tune on them & then use the model for zero shot inferencing on other 300 time series or something like that?
