spaCy is a popular “industrial-strength” NLP library: fast, accurate models with a minimum of fuss. As of spaCy v3, W&B can now be used with spacy train to track your spaCy model’s training metrics as well as to save and version your models and datasets. And all it takes is a few added lines in your configuration.

Sign up and create an API key

An API key authenticates your machine to W&B. You can generate an API key from your user profile.
For a more streamlined approach, you can generate an API key by going directly to the W&B authorization page. Copy the displayed API key and save it in a secure location such as a password manager.
  1. Click your user profile icon in the upper right corner.
  2. Select User Settings, then scroll to the API Keys section.
  3. Click Reveal. Copy the displayed API key. To hide the API key, reload the page.

Install the wandb library and log in

To install the wandb library locally and log in:
  • Command Line
  • Python
  • Python notebook
  1. Set the WANDB_API_KEY environment variable to your API key.
    export WANDB_API_KEY=<your_api_key>
    
  2. Install the wandb library and log in.
    pip install wandb
    
    wandb login
    

Add the WandbLogger to your spaCy config file

spaCy config files are used to specify all aspects of training, not just logging — GPU allocation, optimizer choice, dataset paths, and more. Minimally, under [training.logger] you need to provide the key @loggers with the value "spacy.WandbLogger.v3", plus a project_name.
For more on how spaCy training config files work and on other options you can pass in to customize training, check out spaCy’s documentation.
[training.logger]
@loggers = "spacy.WandbLogger.v3"
project_name = "my_spacy_project"
remove_config_values = ["paths.train", "paths.dev", "corpora.train.path", "corpora.dev.path"]
log_dataset_dir = "./corpus"
model_log_interval = 1000
NameDescription
project_namestr. The name of the W&B Project. The project will be created automatically if it doesn’t exist yet.
remove_config_valuesList[str] . A list of values to exclude from the config before it is uploaded to W&B. [] by default.
model_log_intervalOptional int. None by default. If set, enables model versioning with Artifacts. Pass in the number of steps to wait between logging model checkpoints. None by default.
log_dataset_dirOptional str. If passed a path, the dataset will be uploaded as an Artifact at the beginning of training. None by default.
entityOptional str . If passed, the run will be created in the specified entity
run_nameOptional str . If specified, the run will be created with the specified name.

Start training

Once you have added the WandbLogger to your spaCy training config you can run spacy train as usual.
  • Command Line
  • Python
  • Python notebook
python -m spacy train \
    config.cfg \
    --output ./output \
    --paths.train ./train \
    --paths.dev ./dev
When training begins, a link to your training run’s W&B page will be output which will take you to this run’s experiment tracking dashboard in the W&B web UI.
