Hi, I'm experimenting with NER and trying to understand what all of these values mean:  
E # LOSS TOK2VEC LOSS NER ENTS\_F ENTS\_P ENTS\_R SCORE

I couldn't find this in the documentation. What do they all mean? Specifically for NER but more broadly for all of the training output.

Thanks!

Here `E` refers to epoch, `#` refers to iteration no. and the remaining are the set of scores of particular component. You are getting loss for the Tok2Vec, Precision, Recall, Fscore for the NER. For details: [score types documentation](https://spacy.io/usage/training#score-types) .
