When running nf.predict() for vanilla transformer, I got "can only concatenate str (not "pandas._libs.tslibs.offsets.Hour") to str", any hints? I am following xxxx-xx-xx xxxxxx format. The fit function works fine though. I think there is some issue with the format.

Hi @Yang Guo! Can you add a

<http://pd.to|pd.to>_datetime()

to your

ds

column before the

fit

function?

Thank you! It works now. I realized that the dataset I used though following the format is still in the string type
