Can you please share a tutorial how build a spancat model above spacy blank model?

[steve-solun]

Please post an A-Z tutorial how can I build a spancat model given a spacy blank model (say "en") and DocBin object with my entities and labels.
I have read the docs, this repo and answers of the maintainers but still straggle to build it properly, please provide a simple working example to show how it should work.

You can take a look at our sample projects to see end-to-end implementation of spancat (from preparing DocBin objects to training a model). I suggest looking at the ner_spancat project or spancat_food_ingredients as a starting point.

This may not be related to spancat, but I highly suggest reading through the healthsea blogpost and checking out its corresponding project to get a good sense of how to train spaCy components to your NLP problems.
