Cannot use the ner.gold-to-spacy output JSONL data to train in spacy train

Hi guys, I have a spacy model with tag and dep pipeline only. Then I want to train my current model to understand NER.

So I annotate my examples with Prodigy and use ner.gold-to-spacy with BILUO to export my examples so I can use this examples to train my current model using Spacy.

This is the export result:

["Sampul dari dua singel pertama difoto oleh Emma Summerton pada bulan April 2010 dan tiga gambar lainnya diambil oleh artis yang dirilis untuk mempromosikan album di bulan Juli.

Then I use this command to train my current model using Spacy:

spacy train id Final-Gold-standard\ Model/default/ ner-train.jsonl ner-test.jsonl --base-model id_ud-tag-dep-ner-1.0.0/ --pipeline "ner" --n-iter 1000 -ne 10 --use-gpu 0

But it triggers error like this:

Training pipeline: ['ner']
Starting with base model 'id_ud-tag-dep-ner-1.0.0/'
Counting training words (limit=0)

Please anybody can help? Or @ines / @honnibal can explain?

Or actually I have to do the training with this method "updating NER in spacy" only?
Thank you.

Yes, sorry if this was confusing! ner.gold-to-spacy creates annotations in a format that can be more easily consumed by spaCy – texts and the token-based BILUO tags. We currently don't have a command that directly outputs the JSON training format – also because we're currently working on a new and more intuitive data format that's also more closely aligned with Prodigy's JSONL.

Ok now it is clear :smiley: , and one question again I think, I look at cli/converters folder in spaCy’s GitHub and there’s a jsonl2json converter. What is this for? I mean what kind of jsonl format is this? Thank you

The jsonl2json converter in spaCy should work with Prodigy’s jsonl format. The converter expects very little of the data: just the text key and the spans, which should follow Prodigy’s format. So you should be able to use prodigy db-out and use the resulting jsonl file with spacy convert.
