🪐 spaCy Project: Demo replacing an NER component in a pretrained pipeline

A minimal demo NER project that replaces the NER component in an existing pretrained pipeline. All other pipeline components are preserved and frozen during training.

📋 project.yml

The project.yml defines the data assets required by the project, as well as the available commands and workflows. For details, see the spaCy projects documentation.

⏯ Commands

The following commands are defined by the project. They can be executed using spacy project run [name]. Commands are only re-run if their inputs have changed.

Command	Description
download	Download the pretrained pipeline
convert	Convert the data to spaCy's binary format
create-config	Create a config for replacing only NER from an existing pipeline
train	Train the NER model
evaluate	Evaluate the model and export metrics
package	Package the trained model as a pip package
visualize-model	Visualize the model's output interactively using Streamlit

⏭ Workflows

The following workflows are defined by the project. They can be executed using spacy project run [name] and will run the specified commands in order. Commands are only re-run if their inputs have changed.

Workflow	Steps
all	convert → create-config → train → evaluate

🗂 Assets

The following assets are defined by the project. They can be fetched by running spacy project assets in the project directory.

File	Source	Description
assets/train.json	Local	Demo training data converted from the v2 example scripts with srsly.write_json("train.json", TRAIN_DATA)
assets/dev.json	Local	Demo development data
