Pre-trained models are available here.
Python from_pretrained
method will download the pre-trained model if the provided name (without the extension .tar.gz) matches one of the names in here.
import combo.predict as predict
nlp = predict.SemanticMultitaskPredictor.from_pretrained("polish-herbert-base")
Otherwise it looks for a model in local env.
If you want to use the console version of COMBO, you need to download a pre-trained model manually
wget http://mozart.ipipan.waw.pl/~mklimaszewski/models/polish-herbert-base.tar.gz
and pass it as a parameter (see prediction doc).
