This section documents input and output formats of data used by spaCy, including
|
|
the [training config](/usage/training#config), training data and lexical
|
|
vocabulary data. For an overview of label schemes used by the models, see the
|
|
[models directory](/models). Each trained pipeline documents the label schemes
|
|
used in its components, depending on the data it was trained on.
|
|
|
|
## Training config {#config new="3"}
|
|
|
|
Config files define the training process and pipeline and can be passed to
|
|
[`spacy train`](/api/cli#train). They use
|
|
[Thinc's configuration system](https://thinc.ai/docs/usage-config) under the
|
|
hood. For details on how to use training configs, see the
|
|
[usage documentation](/usage/training#config). To get started with the
|
|
recommended settings for your use case, check out the
|
|
[quickstart widget](/usage/training#quickstart) or run the
|
|
[`init config`](/api/cli#init-config) command.
|
|
|
|
> #### What does the @ mean?
|
|
>
|
|
> The `@` syntax lets you refer to function names registered in the
|
|
> [function registry](/api/top-level#registry). For example,
|
|
> `@architectures = "spacy.HashEmbedCNN.v1"` refers to a registered function of
|
|
> the name [spacy.HashEmbedCNN.v1](/api/architectures#HashEmbedCNN) and all
|
|
> other values defined in its block will be passed into that function as
|
|
> arguments. Those arguments depend on the registered function. See the usage
|
|
> guide on [registered functions](/usage/training#config-functions) for details.

<Infobox title="Notes on data validation" emoji="💡">
|
|
|
|
Under the hood, spaCy's configs are powered by our machine learning library
|
|
[Thinc's config system](https://thinc.ai/docs/usage-config), which uses
|
|
[`pydantic`](https://github.com/samuelcolvin/pydantic/) for data validation
|
|
based on type hints. See [`spacy/schemas.py`](%%GITHUB_SPACY/spacy/schemas.py)
|
|
for the schemas used to validate the default config. Arguments of registered
|
|
functions are validated against their type annotations, if available. To debug
|
|
your config and check that it's valid, you can run the
|
|
[`spacy debug config`](/api/cli#debug-config) command.

This section includes definitions of the
|
|
[pipeline components](/usage/processing-pipelines) and their models, if
|
|
available. Components in this section can be referenced in the `pipeline` of the
|
|
`[nlp]` block. Component blocks need to specify either a `factory` (named
|
|
function to use to create component) or a `source` (name of path of trained
|
|
pipeline to copy components from). See the docs on
|
|
[defining pipeline components](/usage/training#config-components) for details.
|
|
|
|
### paths, system {#config-variables tag="variables"}
|
|
|
|
These sections define variables that can be referenced across the other sections
|
|
as variables. For example `${paths.train}` uses the value of `train` defined in
|
|
the block `[paths]`. If your config includes custom registered functions that
|
|
need paths, you can define them here. All config values can also be
|
|
[overwritten](/usage/training#config-overrides) on the CLI when you run
|
|
[`spacy train`](/api/cli#train), which is especially relevant for data paths
|
|
that you don't want to hard-code in your config file.
|
|
|
|
```cli
|
|
$ python -m spacy train config.cfg --paths.train ./corpus/train.spacy
|
|
```
|
|
|
|

## Training data {#training}
|
|
|
|
### Binary training format {#binary-training new="3"}
|
|
|
|
> #### Example
|
|
>
|
|
> ```python
|
|
> from spacy.tokens import DocBin
|
|
> from spacy.training import Corpus
|
|
>
|
|
> doc_bin = DocBin(docs=docs)
|
|
> doc_bin.to_disk("./data.spacy")
|
|
> reader = Corpus("./data.spacy")
|
|
> ```
|
|
|
|
The main data format used in spaCy v3.0 is a **binary format** created by
|
|
serializing a [`DocBin`](/api/docbin), which represents a collection of `Doc`
|
|
objects. This means that you can train spaCy pipelines using the same format it
|
|
outputs: annotated `Doc` objects. The binary format is extremely **efficient in
|
|
storage**, especially when packing multiple documents together.
|
|
|
|
Typically, the extension for these binary files is `.spacy`, and they are used
|
|
as input format for specifying a [training corpus](/api/corpus) and for spaCy's
|
|
CLI [`train`](/api/cli#train) command. The built-in
|
|
[`convert`](/api/cli#convert) command helps you convert spaCy's previous
|
|
[JSON format](#json-input) to the new binary format format. It also supports
|
|
conversion of the `.conllu` format used by the
|
|
[Universal Dependencies corpora](https://github.com/UniversalDependencies).
|
|
|
|
### JSON training format {#json-input tag="deprecated"}
|
|
|
|
<Infobox variant="warning" title="Changed in v3.0">
|
|
|
|
As of v3.0, the JSON input format is deprecated and is replaced by the
|
|
[binary format](#binary-training). Instead of converting [`Doc`](/api/doc)
|
|
objects to JSON, you can now serialize them directly using the
|
|
[`DocBin`](/api/docbin) container and then use them as input data.
|
|
|
|
[`spacy convert`](/api/cli) lets you convert your JSON data to the new `.spacy`
|
|
format:
|
|
|
|
```cli
|
|
$ python -m spacy convert ./data.json ./output.spacy
|
|
```
|
|
|
|
</Infobox>
|
|
|
|
> #### Annotating entities
|
|
>
|
|
> Named entities are provided in the
|
|
> [BILUO](/usage/linguistic-features#accessing-ner) notation. Tokens outside an
|
|
> entity are set to `"O"` and tokens that are part of an entity are set to the
|
|
> entity label, prefixed by the BILUO marker. For example `"B-ORG"` describes
|
|
> the first token of a multi-token `ORG` entity and `"U-PERSON"` a single token
|
|
> representing a `PERSON` entity. The
|
|
> [`biluo_tags_from_offsets`](/api/top-level#biluo_tags_from_offsets) function
|
|
> can help you convert entity offsets to the right format.
|
|

Here's an example of dependencies, part-of-speech tags and names entities, taken
|
|
from the English Wall Street Journal portion of the Penn Treebank:
|
|
|
|
```json

|
|
|
### Annotation format for creating training examples {#dict-input}
|
|
|
|
An [`Example`](/api/example) object holds the information for one training
|
|
instance. It stores two [`Doc`](/api/doc) objects: one for holding the
|
|
gold-standard reference data, and one for holding the predictions of the
|
|
pipeline. Examples can be created using the
|
|
[`Example.from_dict`](/api/example#from_dict) method with a reference `Doc` and
|
|
a dictionary of gold-standard annotations.
|
|
|
|
> #### Example
|
|
>
|
|
> ```python
|
|
> example = Example.from_dict(doc, gold_dict)
|
|
> ```
|
|
|
|
<Infobox title="Important note" variant="warning">
|
|
|
|
`Example` objects are used as part of the
|
|
[internal training API](/usage/training#api) and they're expected when you call
|
|
[`nlp.update`](/api/language#update). However, for most use cases, you
|
|
**shouldn't** have to write your own training scripts. It's recommended to train
|
|
your pipelines via the [`spacy train`](/api/cli#train) command with a config
|
|
file to keep track of your settings and hyperparameters and your own
|
|
[registered functions](/usage/training/#custom-code) to customize the setup.

|
<Infobox title="Notes and caveats">
|
|
|
|
- Multiple formats are possible for the "entities" entry, but you have to pick
|
|
one.
|
|
- Any values for sentence starts will be ignored if there are annotations for
|
|
dependency relations.
|
|
- If the dictionary contains values for `"text"` and `"words"`, but not
|
|
`"spaces"`, the latter are inferred automatically. If "words" is not provided
|
|
either, the values are inferred from the `Doc` argument.

doc = Doc(vocab, words=["I", "like", "stuff"])
|
|
gold_dict = {"tags": ["NOUN", "VERB", "NOUN"]}
|

|
|
|
|
# Training data for an entity recognizer (option 2)
|
|
doc = nlp("Laura flew to Silicon Valley.")
|
|
gold_dict = {"entities": [(0, 5, "PERSON"), (14, 28, "LOC")]}
|
|
example = Example.from_dict(doc, gold_dict)
|
|
|
|
# Training data for text categorization
|
|
doc = nlp("I'm pretty happy about that!")
|
|
gold_dict = {"cats": {"POSITIVE": 1.0, "NEGATIVE": 0.0}}
|
|
example = Example.from_dict(doc, gold_dict)
|
|
|
|
# Training data for an Entity Linking component
|
|
doc = nlp("Russ Cochran his reprints include EC Comics.")
|
|
gold_dict = {"links": {(0, 12): {"Q7381115": 1.0, "Q2146908": 0.0}}}

```
|
|
|
|
## Lexical data for vocabulary {#vocab-jsonl new="2"}
|
|
|
|
To populate a pipeline's vocabulary, you can use the
|
|
[`spacy init vocab`](/api/cli#init-vocab) command and load in a
|
|
[newline-delimited JSON](http://jsonlines.org/) (JSONL) file containing one
|
|
lexical entry per line via the `--jsonl-loc` option. The first line defines the
|
|
language and vocabulary settings. All other lines are expected to be JSON
|
|
objects describing an individual lexeme. The lexical attributes will be then set
|
|
as attributes on spaCy's [`Lexeme`](/api/lexeme#attributes) object. The `vocab`
|
|
command outputs a ready-to-use spaCy pipeline with a `Vocab` containing the
|
|
lexical data.
|
|
|

## Pipeline meta {#meta}
|
|
|
|
The pipeline meta is available as the file `meta.json` and exported
|
|
automatically when you save an `nlp` object to disk. Its contents are available
|
|
as [`nlp.meta`](/api/language#meta).
|
|
|
|
<Infobox variant="warning" title="Changed in v3.0">
|
|
|
|
As of spaCy v3.0, the `meta.json` **isn't** used to construct the language class
|
|
and pipeline anymore and only contains meta information for reference and for
|
|
creating a Python package with [`spacy package`](/api/cli#package). How to set
|
|
up the `nlp` object is now defined in the
|
|
[`config.cfg`](/api/data-formats#config), which includes detailed information
|
|
about the pipeline components and their model architectures, and all other
|
|
settings and hyperparameters used to train the pipeline. It's the **single
|
|
source of truth** used for loading a pipeline.

|
|
| `lang` | Pipeline language [ISO code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes). Defaults to `"en"`. ~~str~~ |
|
|
| `name` | Pipeline name, e.g. `"core_web_sm"`. The final package name will be `{lang}_{name}`. Defaults to `"pipeline"`. ~~str~~ |

|
|
| `spacy_version` | spaCy version range the package is compatible with. Defaults to the spaCy version used to create the pipeline, up to next minor version, which is the default compatibility for the available [trained pipelines](/models). For instance, a pipeline trained with v3.0.0 will have the version range `">=3.0.0,<3.1.0"`. ~~str~~ |
|
|
| `parent_package` | Name of the spaCy package. Typically `"spacy"` or `"spacy_nightly"`. Defaults to `"spacy"`. ~~str~~ |
|
|
| `description` | Pipeline description. Also used for Python package. Defaults to `""`. ~~str~~ |
|
|
| `author` | Pipeline author name. Also used for Python package. Defaults to `""`. ~~str~~ |
|
|
| `email` | Pipeline author email. Also used for Python package. Defaults to `""`. ~~str~~ |
|
|
| `url` | Pipeline author URL. Also used for Python package. Defaults to `""`. ~~str~~ |
|
|
| `license` | Pipeline license. Also used for Python package. Defaults to `""`. ~~str~~ |
|
|
| `sources` | Data sources used to train the pipeline. Typically a list of dicts with the keys `"name"`, `"url"`, `"author"` and `"license"`. [See here](https://github.com/explosion/spacy-models/tree/master/meta) for examples. Defaults to `None`. ~~Optional[List[Dict[str, str]]]~~ |
|
|
| `vectors` | Information about the word vectors included with the pipeline. Typically a dict with the keys `"width"`, `"vectors"` (number of vectors), `"keys"` and `"name"`. ~~Dict[str, Any]~~ |
|
|
| `pipeline` | Names of pipeline component names, in order. Corresponds to [`nlp.pipe_names`](/api/language#pipe_names). Only exists for reference and is not used to create the components. This information is defined in the [`config.cfg`](/api/data-formats#config). Defaults to `[]`. ~~List[str]~~ |
|
|
| `labels` | Label schemes of the trained pipeline components, keyed by component name. Corresponds to [`nlp.pipe_labels`](/api/language#pipe_labels). [See here](https://github.com/explosion/spacy-models/tree/master/meta) for examples. Defaults to `{}`. ~~Dict[str, Dict[str, List[str]]]~~ |
