catalogue.RegistryError: [E893] Could not find function 'spacy.copy_from_base_model.v1' in function registry 'callbacks'

I'm Spacy's new user and I'm trying to run this ner_demo_update project and I got this error :
catalogue.RegistryError: [E893] Could not find function 'spacy.copy_from_base_model.v1' in function registry 'callbacks'. If you're using a custom function, make sure the code is available. If the function is provided by a third-party package, e.g. spacy-transformers, make sure the package is installed in your environment.
I would like to know if anyone faced the same problem

Hi, please update to spacy v3.0.6+.

I think that spacy project commands should show a warning if you have an earlier version than this, but I can double-check that all the settings in this demo project are correct...

This particular project is not intended to run with <3.0.6, so you'll need to upgrade. If you are not running this particular project, please provide more details.

Can you clarify why you can't upgrade? Changes between 3.0.5 and 3.0.6 shouldn't be that drastic, and in particular it shouldn't break anything.

Hey @polm , thanks for your reply.

I am building custom NER component in a blank model. I am using v3.0.5 because my organisation recommended it. I have already trained the model in v3.0.6 and it is working absolutely fine. But I am getting the same error mentioned here in 3.0.5. How to solve it or is there any different method to train for older versions?

[polm]

We don't have any particular alternative to upgrading in this case, no. You could copy the relevant commits into your local code but that's basically a more complicated way of upgrading. I would suggest you discuss upgrading with your organization.

[dhruvbhimani-2512]

Then how models were being trained before v3.0.6? Could you please tell?

[polm]

You can use spacy init config to create a config compatible with the particular version you're using.
