How to overwrite spans of Example object?

[jamnicki]

Hello!
I need to overwrite spans list of existing Example object.

example["doc_annotation"]["spans"][spans_key] = new_span_group

I encoutered following error executing above code and I have no idea of fix:

TypeError: 'spacy.training.example.Example' object is not subscriptable

Do I need to create new Example object based on data from already existing? How can I do this?

Hi @jamnicki , I'm curious as to why you're overwriting spans in the Example object, are you trying to train using a custom training loop, etc.? But to answer your question, you should only update the reference attribute of your Example object (Example.reference is a Doc).

example.reference.spans[spans_key] = span_group

Thank you again @ljvmiranda921!
I'm implementing active learning loop on unlabeled data. Long story short, get batch of unlabeled records basing on some informativeness metrics, annotate the data in the GUI, get annotations (there I have to do this), train, repeat 😃
