FloatingPointError: underflow encountered in exp

[CoteDave]

catboost version: 2.5.1
numpy version: 1.23.3

t_encoder= TargetEncoder(min_samples_leaf=20, smoothing=10)
t_encoded = t_encoder.fit_transform(new_xy_test_dummy[[cat_col]].astype(str), new_xy_test_dummy[[target_col]], cols = [cat_col])

No nans...

Same data seems to work with WOE encoder. Encountered the problem only with TargetEncoder:
w_encoder= WOEEncoder()
w_encoded = w_encoder.fit_transform(new_xy_test_dummy[[cat_col]].astype(str), new_xy_test_dummy[[target_col]], cols = [cat_col]) = works!

Any Ideas ?

Thanks !

can you please provide some data in order to reproduce this and also format your code as code (for better readability)

There is an easy and long awaited fix.

But we still need data example (or specific values, in this case very small ones) for testing purposes.
