Problem:

_catboost.pyx in _catboost._set_features_order_data_pd_data_frame()

_catboost.pyx in _catboost.get_cat_factor_bytes_representation()

CatBoostError: Invalid type for cat_feature[non-default value idx=1,feature_idx=336]=2.0 : cat_features must be integer or string, real number values and NaN values should be converted to string.

Could you also print a feature name, not o

For the autoencoder in pyod, how do I adjust the learning rate?

The Aggregator incorrectly assumes that all hierarchy levels are named, in contrast to the specification of pd_multiindex_hier which does not. The estimator breaks when receiving input where at least one level is not named.

#2432 proposes a temp workaround, but this should be:

• cleaned up so the inner logic of Aggregator no longer assumes it
• tested, so we ensure in all estimators t

Unless I missed something, the documentation doesn't explain how to query document metadata (searching "site:montferret.dev metadata" through Google returned nothing, neither did grepping the source code).

As an example, I tried to query the og:url metadata.
I tried variations of //meta[property='og:url']::attr(content), with or without the leading //, and with or without the `attr(conte
