Retrain an existing model with new data of the same entity, and add new entities. Spacy v3

[berrodriquez26]

Hello. I am making a model with 10 different entities, and I don´t want to train all the model at once. The problem is that I haven´t found anything useful on the internet. Can someone explain me step by step how to retrain an existing model in spacy using the version 3 please. There are a lot of information but spacy version 2 is being used.

But I want a step by step guide to re train the model. Also, I know it is better to train all the model at once, but I want to do it in parts.

Hi @berrodriquez26,

The best way to see how retraining a NER model works is to check the ner_demo_update project. If you want a step-by-step guide, you can check each step in the project's project.yml file workflows. From there, you should be able to pattern the project on your own dataset / use case.

If you're not familiar on how spaCy Projects work, feel free to check the documentation. You only need to install spaCy and you'll have access to the spacy project command. You can also clone the said ner_demo_update project using spacy project clone.
