How to export the list of original features?

[YenTran32]

Hi everyone,

Could anyone know how to export the list of orginal features?

I follow this example. After fitting the model, running this crf.training_log_.log will print out the log, which you can see the innitial number of features (and also the number of active features):

My question is, is there anyway to export this list of original features? Is it calculated separately for state features and transition features, and then summing them?

Many thanks.

Tran.
