Why none of the models work on weekly frequency?

[madscrypter]

When i work with daily data I can use NBEATS and NHITS but when I set my data with freq="W" ( my data are weekly in Year-month-day format ) all the predictions turn to be NaN

hi @madscrypter. Thanks for using neuralforecast. Could you paste a head of your ds column? Usually, weekly frequency has a particular way of encoding it depending on the day of the week. For example, if the week is represented each Thursday, the correct frequency would be W-THU, or W-MON if it is represented each Monday. By default, W is W-SUN. See this reference.
