Hi, I have a question regarding the tok2vec component in the pipeline. I'm training a custom NER model as described in your previous videos in spaCy 3.0 i.e. first creating a dataset using the EntityRuler approach and training an NER model. I have done this for three labels and trained a combined NER model. Now the NER loss decreases (approximately 250) but the tok2vec loss is pretty high (approximately 20, 000) for the best model (when the metric is selected as recall). Do you know why this could be happening and if this appropriate?

Dr. Mattingly, I've come across an error while training my pipeline. I somehow get only Scores of 0 throughout the whole process (ENTS_F, ENTS_P and ENTS_R as well). But spacy seem to not throw any error. I can successfully load my saved model into nlp() and use it to determine custom entities on new texts. How is that possible and is it crucial for my model? Or do I need to 'retrain' my model to make it more precise? I'm kinda stumped.

Thank you for all the videos, I would like to know if there is any way to calculate the amount of memory needed to train SpacyV3 transformers models and the number of batch recommended for it ?! thank you

Can you re-train an already trained spacy model, WITHOUT having to feed the "updated" model ALL the previously-seen samples?

Convolutional neural networks for the win.

Thank you for the video. How exactly can we validate a model in Spacy V3? Can't find any related documentation on that..

[vaibhaves]

can we use the same config for more than one model, if we edit the parameters?

[nebupulickal]

Is it possible to create ui for the ner training process using flask app.

I wan't to know if spacy v3 support overlap in entities and what good method to di this, thank's

[!] Aborting and saving the final best model. Encountered exception:
ValueError("[E869] The notation 'B-!= statement' is not supported anymore. To
annotate negative NER samples, use `doc.spans[key]` instead, and specify the key
as 'incorrect_spans_key' when constructing the NER component.")



I get the above error while running the command which should Initialize the pipeline and prepare the model file. How do I solve this?

[akashnambiar]

from Spacy 3.2 onwards, you could train from Python itself rather than using CLI

[nhutranquynh]

I don't know what the format of my own data is so that spacy can train it?

How to retrain ner model with new data
is it the same way?...

Thank u...

How would you train for data where you could have something like Western is the specific name of a council, Western could be a place name, or a person name.

Western J. A, 2016 - Western Landforms modelling approach, NSW etc, We have multiple combinations where the 'entity search' is multiple types. Our goal is to run on over 100k records of title & description
