Train NER based on existing model or add custom trained NER to existing model error #7135
Description
in spaCy < 3.0 I was able to train the NER component within the trained en_core_web_sm model:
python -m spacy train en model training validation --base-model en_core_web_sm --pipeline "ner" -R -n 10
Specifically, I need the tagger and in the parser of the en_core_web_lg model. These components can be added with the corresponding source and then insert to the frozen_component in the training section of the config file (I will provide my full config at the end of this question):
`[components]
[components.tagger]
source = "en_core_web_sm"
replace_listeners = ["model.tok2vec"]
[components.parser]
source = "en_core_web_sm"
replace_listeners = ["model.tok2vec"]
.
.
.
[training]
frozen_components = ["tagger","parser"]`
When I'm debugging, following error occurs:
ValueError: [E922] Component 'tagger' has been initialized with an output dimension of 49 - cannot add any more labels.
When I put tagger to the disabled components in the nlp section of the config file or if I delete everything related to the tagger, debugging and training works. However, when applying the trained model to a text loaded to a doc, only the trained NER works and none of the other components. E.g. the parser predicts everything is ROOT.
I also tried to train the NER model on its own and then add it to the loaded en_core_web_sm model:
`MODEL_PATH = 'data/model/model-best'
nlp = spacy.load(MODEL_PATH)
english_nlp = spacy.load("en_core_web_sm")
ner_labels = nlp.get_pipe("ner")
english_nlp.add_pipe('ner_labels')`
This leads to the following error:
ValueError: [E002] Can't find factory for 'ner_labels' for language English (en). This usually happens when spaCy calls nlp.create_pipe with a custom component name that's not registered on the current language class. If you're using a Transformer, make sure to install 'spacy-transformers'. If you're using a custom component, make sure you've added the decorator @Language.component(for function components) or@Language.factory` (for class components).
Available factories: attribute_ruler, tok2vec, merge_noun_chunks, merge_entities, merge_subtokens, token_splitter, parser, beam_parser, entity_linker, ner, beam_ner, entity_ruler, lemmatizer, tagger, morphologizer, senter, sentencizer, textcat, textcat_multilabel, en.lemmatizer`
Does anyone have a suggestion how I can either train my NER with the en_core_web_sm model or how I could integrate my trained component?
