Hi @Marco Zucchini! Can you show an example of the date? Can you try with

df['ds']=<http://pd.to|pd.to>_datetime(df['ds'])

?

Hi Cristian, thank you for quick reply! I was using:

df['ds']=<http://pd.to|pd.to>_datetime(df['Date'], utc=True).dt.date

, now I changed as you said but keeping

utc=True

and got now the date in the format e.g. 2021-08-31 040000+00:00. That error is not there anymore but somehow I have a new trouble (!)

CUDA unknown error - this may be due to an incorrectly set up environment

For the sake of overcome it quickly I have tried to switch to cpu but it does not work: how can I force cpu instead of gpu? not like that?

torch.cuda.is_available = lambda : False

Thanks!
