Using spaCy for finetuning a NER model in spaCy 3.0

I want to use en_core_web_trf model in spaCy library for Named entity recognition. However, the guide for training a custom model does not contain information for finetuning a pretrained model.

How can one finetune an NER model in spaCy v3.0?

It's recommended you train your NER component from scratch rather than fine-tuning the existing model, because fine-tuning the existing model is prone to catastrophic forgetting. Note that even if your NER component is trained from scratch, you're still using the Transformer as a starting point, so you aren't starting from nothing.

More details about why not to re-train the existing NER, and how to do it if you want to, are in the FAQ. There are also many threads about this topic in the Discussion in general.
