Updating an already existing spacy NER model

Question

I want to update and already existing spacy model 'en_core_web_sm' and train it with additional data.

My data is in the same format as mentioned in spacy's documentation https://spacy.io/usage/training

I've followed the same steps as mentioned in the documentation for updating an NER model with my data.

def model_train(output_dir=None, n_iter=100):
    """Load the model, set up the pipeline and train the entity recognizer."""
    model=('en_core_web_sm')
    nlp = spacy.load(model, entity = False, parser = False)  # load existing spaCy model
    print("Loaded model '%s'" % model)
    print (nlp.pipe_names)

#     # create the built-in pipeline components and add them to the pipeline

    ner = nlp.get_pipe("ner")

#     # add labels
    for texts, annotations in TRAIN_DATA:        
        for ent in annotations.get("entities"):
#             print (ent)
            ner.add_label(ent[2])
#             print (ent[2])

    other_pipes = [pipe for pipe in nlp.pipe_names if pipe != "ner"]
    with nlp.disable_pipes(*other_pipes):  # only train NER

        if model is None:
            nlp.begin_training()
        for itn in range(n_iter):
            random.shuffle(TRAIN_DATA)
            losses = {}
#             # batch up the examples using spaCy's minibatch
            batches = minibatch(TRAIN_DATA, size=compounding(4.0, 32.0, 1.001))
            for batch in batches:
                texts, annotations = zip(*batch)
                nlp.update(
                    [texts],  # batch of texts
                    [annotations],  # batch of annotations
                    drop=0.5,  # dropout - make it harder to memorise data
                    losses=losses,
                )
            print("Losses", losses)


        nlp.to_disk(output_dir)
        print("Saved model to", output_dir)

The error that I'm getting is

Loaded model 'en_core_web_sm'
['tagger', 'parser', 'ner']

Answer 1

zip() already sending list of texts and annotation

nlp.update(
                    texts,  # batch of texts
                    annotations,  # batch of annotations
                    drop=0.5,  # dropout - make it harder to memorise data
                    losses=losses,
                )
