<!-- TODO: add notes on autocompletion etc. -->
|
||
|
||
## Download {#download}
|
||
|
||
Download [models](/usage/models) for spaCy. The downloader finds the
|
||
best-matching compatible version and uses `pip install` to download the model as
|
||
a package. Direct downloads don't perform any compatibility checks and require
|
||
the model name to be specified with its version (e.g. `en_core_web_sm-2.2.0`).
|
||
|
||
> #### Downloading best practices
|
||
>
|
||
> The `download` command is mostly intended as a convenient, interactive wrapper
|
||
> – it performs compatibility checks and prints detailed messages in case things
|
||
> go wrong. It's **not recommended** to use this command as part of an automated
|
||
> process. If you know which model your project needs, you should consider a
|
||
> [direct download via pip](/usage/models#download-pip), or uploading the model
|
||
> to a local PyPi installation and fetching it straight from there. This will
|
||
> also allow you to add it as a versioned package dependency to your project.
|
||
|
||
```bash
|
||
$ python -m spacy download [model] [--direct] [pip args]
|
||
```
|
||
|
||
| Argument | Type | Description |
|
||
| ------------------------------------- | ---------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

|
||
| `--direct`, `-d` | flag | Force direct download of exact model version. |
|
||

|
||
| `--help`, `-h` | flag | Show help message and available arguments. |
|
||
| **CREATES** | directory | The installed model package in your `site-packages` directory. |
|

|
||
## Info {#info}
|
||
|
||
Print information about your spaCy installation, models and local setup, and
|
||

|
||
copy-paste into [GitHub issues](https://github.com/explosion/spaCy/issues).
|
||
|
||
```bash
|
||
$ python -m spacy info [--markdown] [--silent]

|
||
## Validate {#validate new="2"}
|
||
|
||
Find all models installed in the current environment and check whether they are
|
||
compatible with the currently installed version of spaCy. Should be run after
|
||
upgrading spaCy via `pip install -U spacy` to ensure that all installed models
|
||
are can be used with the new version. It will show a list of models and their
|
||
installed versions. If any model is out of date, the latest compatible versions
|
||
and command for updating are shown.
|
||
|
||
> #### Automated validation
|
||
>
|
||
> You can also use the `validate` command as part of your build process or test
|
||
> suite, to ensure all models are up to date before proceeding. If incompatible
|
||
> models are found, it will return `1`.
|
||
|
||
```bash
|
||
$ python -m spacy validate
|
||
```
|

||
[binary training data format](/api/data-formats#binary-training), a serialized
|
||
[`DocBin`](/api/docbin), for use with the `train` command and other experiment
|
||
management functions. The converter can be specified on the command line, or
|
||
chosen based on the file extension of the input file.
|
||
|
||
```bash
|
||
$ python -m spacy convert [input_file] [output_dir] [--converter]

### Converters
|
||
|
||
| ID | Description |
|
||
| ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||
| `auto` | Automatically pick converter based on file extension and file content (default). |
|
||
| `json` | JSON-formatted training data used in spaCy v2.x and produced by [`docs2json`](/api/top-level#docs_to_json). |
|
||
| `conll` | Universal Dependencies `.conllu` or `.conll` format. |
|
||
| `ner` | NER with IOB/IOB2 tags, one token per line with columns separated by whitespace. The first column is the token and the final column is the IOB tag. Sentences are separated by blank lines and documents are separated by the line `-DOCSTART- -X- O O`. Supports CoNLL 2003 NER format. See [sample data](https://github.com/explosion/spaCy/tree/master/examples/training/ner_example_data). |
|
||
| `iob` | NER with IOB/IOB2 tags, one sentence per line with tokens separated by whitespace and annotation separated by `|`, either `word|B-ENT` or `word|POS|B-ENT`. See [sample data](https://github.com/explosion/spaCy/tree/master/examples/training/ner_example_data). |
|
||
|
||
## Debug {#debug new="3"}
|
||
|
||
The `spacy debug` CLI includes helpful commands for debugging and profiling your
|
||
configs, data and implementations.
|
||
|
||
### debug config {#debug-config}
|
||
|
||
Debug a [`config.cfg` file](/usage/training#config) and show validation errors.
|
||
The command will create all objects in the tree and validate them. Note that
|
||
some config validation errors are blocking and will prevent the rest of the
|
||
config from being resolved. This means that you may not see all validation
|
||
errors at once and some issues are only shown once previous errors have been
|
||
fixed.
|
||
|
||
```bash
|
||
$ python -m spacy debug config [config_path] [--code] [overrides]
|
||
```
|
||
|
||
> #### Example
|
||
>
|

⚠ Multiple root labels (ROOT, nsubj, aux, npadvmod, prep) found in
|

## Train {#train}
|
||
|
||
Train a model. Expects data in spaCy's
|
||
[binary format](/api/data-formats#training) and a
|
||
[config file](/api/data-formats#config) with all settings and hyperparameters.
|
||
Will save out the best model from all epochs, as well as the final model. The
|
||
`--code` argument can be used to provide a Python file that's imported before
|
||
the training process starts. This lets you register
|
||
[custom functions](/usage/training#custom-models) and architectures and refer to
|
||
them in your config, all while still using spaCy's built-in `train` workflow. If
|
||
you need to manage complex multi-step training workflows, check out the new
|
||
[spaCy projects](/usage/projects).
|
||
|
||
<Infobox title="New in v3.0" variant="warning">
|
||
|
||
The `train` command doesn't take a long list of command-line arguments anymore
|
||
and instead expects a single [`config.cfg` file](/usage/training#config)
|
||
containing all settings for the pipeline, training process and hyperparameters.

## Pretrain {#pretrain new="2.1" tag="experimental"}
|
||
|
||
<!-- TODO: document new pretrain command and link to new pretraining docs -->
|
||
|
||
Pre-train the "token to vector" (`tok2vec`) layer of pipeline components, using
|
||
an approximate language-modeling objective. Specifically, we load pretrained
|
||
vectors, and train a component like a CNN, BiLSTM, etc to predict vectors which
|
||
match the pretrained ones. The weights are saved to a directory after each
|
||
epoch. You can then pass a path to one of these pretrained weights files to the
|
||
`spacy train` command. This technique may be especially helpful if you have
|
||
little labelled data.
|
||
|
||
<Infobox title="Changed in v3.0" variant="warning">
|
||
|
||
As of spaCy v3.0, the `pretrain` command takes the same
|
||
[config file](/usage/training#config) as the `train` command. This ensures that
|
||
settings are consistent between pretraining and training. Settings for
|
||
pretraining can be defined in the `[pretraining]` block of the config file. See
|
||
the [data format](/api/data-formats#config) for details.

|
||
| Argument | Type | Description |
|
||
| ----------------------- | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||
| `texts_loc` | positional | Path to JSONL file with raw texts to learn from, with text provided as the key `"text"` or tokens as the key `"tokens"`. [See here](#pretrain-jsonl) for details. |
|
||
| `output_dir` | positional | Directory to write models to on each epoch. |
|
||
| `config_path` | positional | Path to [training config](/api/data-formats#config) file containing all settings and hyperparameters. |
|

|
||
| **CREATES** | weights | The pretrained weights that can be used to initialize `spacy train`. |
|
||
|
||
### JSONL format for raw text {#pretrain-jsonl}
|
||
|
||
Raw text can be provided as a `.jsonl` (newline-delimited JSON) file containing
|
||
one input text per line (roughly paragraph length is good). Optionally, custom
|
||
tokenization can be provided.
|
||
|
||
> #### Tip: Writing JSONL
|
||
>
|
||
> Our utility library [`srsly`](https://github.com/explosion/srsly) provides a
|
||
> handy `write_jsonl` helper that takes a file path and list of dictionaries and
|
||
> writes out JSONL-formatted data.
|
||
>
|
||
> ```python
|
||
> import srsly
|
||
> data = [{"text": "Some text"}, {"text": "More..."}]
|
||
> srsly.write_jsonl("/path/to/text.jsonl", data)
|
||
> ```
|
||
|
||
| Key | Type | Description |
|
||
| -------- | ---- | ---------------------------------------------------------- |
|
||
| `text` | str | The raw input text. Is not required if `tokens` available. |
|
||
| `tokens` | list | Optional tokenization, one string per token. |
|
||
|
||
```json
|
||
### Example
|
||
{"text": "Can I ask where you work now and what you do, and if you enjoy it?"}
|
||
{"text": "They may just pull out of the Seattle market completely, at least until they have autonomous vehicles."}
|
||
{"text": "My cynical view on this is that it will never be free to the public. Reason: what would be the draw of joining the military? Right now their selling point is free Healthcare and Education. Ironically both are run horribly and most, that I've talked to, come out wishing they never went in."}
|
||
{"tokens": ["If", "tokens", "are", "provided", "then", "we", "can", "skip", "the", "raw", "input", "text"]}
|
||
```
|
||
|
||
## Init Model {#init-model new="2"}
|
||
|
||
Create a new model directory from raw data, like word frequencies, Brown
|
||
clusters and word vectors. This command is similar to the `spacy model` command
|
||
in v1.x. Note that in order to populate the model's vocab, you need to pass in a
|
||
JSONL-formatted [vocabulary file](/api/data-formats#vocab-jsonl) as
|
||
`--jsonl-loc` with optional `id` values that correspond to the vectors table.
|
||
Just loading in vectors will not automatically populate the vocab.
|
||
|
||
```bash
|
||
$ python -m spacy init-model [lang] [output_dir] [--jsonl-loc] [--vectors-loc]
|
||
[--prune-vectors]
|
||
```
|
||
|
||
| Argument | Type | Description |
|
||
| ----------------------------------------------------------- | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
|
||
| `lang` | positional | Model language [ISO code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes), e.g. `en`. |
|
||
| `output_dir` | positional | Model output directory. Will be created if it doesn't exist. |
|
||
| `--jsonl-loc`, `-j` | option | Optional location of JSONL-formatted [vocabulary file](/api/data-formats#vocab-jsonl) with lexical attributes. |
|
||
| `--vectors-loc`, `-v` | option | Optional location of vectors. Should be a file where the first row contains the dimensions of the vectors, followed by a space-separated Word2Vec table. File can be provided in `.txt` format or as a zipped text file in `.zip` or `.tar.gz` format. |
|
||
| `--truncate-vectors`, `-t` <Tag variant="new">2.3</Tag> | option | Number of vectors to truncate to when reading in vectors file. Defaults to `0` for no truncation. |
|
||
| `--prune-vectors`, `-V` | option | Number of vectors to prune the vocabulary to. Defaults to `-1` for no pruning. |
|
||
| `--vectors-name`, `-vn` | option | Name to assign to the word vectors in the `meta.json`, e.g. `en_core_web_md.vectors`. |
|
||
| `--omit-extra-lookups`, `-OEL` <Tag variant="new">2.3</Tag> | flag | Do not include any of the extra lookups tables (`cluster`/`prob`/`sentiment`) from `spacy-lookups-data` in the model. |
|
||
| **CREATES** | model | A spaCy model containing the vocab and vectors. |
|
||
|
||
## Evaluate {#evaluate new="2"}
|
||
|
||
<!-- TODO: document new evaluate command -->
|
||
|
||
Evaluate a model's accuracy and speed on JSON-formatted annotated data. Will
|
||
print the results and optionally export
|
||
[displaCy visualizations](/usage/visualizers) of a sample set of parses to
|
||
`.html` files. Visualizations for the dependency parse and NER will be exported
|
||
as separate files if the respective component is present in the model's
|
||
pipeline.
|
||
|
||
```bash
|
||
$ python -m spacy evaluate [model] [data_path] [--output] [--displacy-path]
|
||
[--displacy-limit] [--gpu-id] [--gold-preproc]
|
||
```
|
||
|
||
| Argument | Type | Description |
|
||
| ------------------------- | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||
| `model` | positional | Model to evaluate. Can be a package or a path to a model data directory. |
|
||
| `data_path` | positional | Location of evaluation data in spaCy's [binary format](/api/data-formats#training). |
|
||
| `--output`, `-o` | option | Output JSON file for metrics. If not set, no metrics will be exported. |
|
||
| `--displacy-path`, `-dp` | option | Directory to output rendered parses as HTML. If not set, no visualizations will be generated. |
|
||
| `--displacy-limit`, `-dl` | option | Number of parses to generate per file. Defaults to `25`. Keep in mind that a significantly higher number might cause the `.html` files to render slowly. |
|
||
| `--gpu-id`, `-g` | option | GPU to use, if any. Defaults to `-1` for CPU. |
|
||
| `--gold-preproc`, `-G` | flag | Use gold preprocessing. |
|
||
| **CREATES** | `stdout`, JSON, HTML | Training results and optional metrics and visualizations. |
|
||
|
||
## Package {#package}
|
||
|
||
Generate an installable
|
||
[model Python package](/usage/training#models-generating) from an existing model
|
||
data directory. All data files are copied over. If the path to a `meta.json` is
|
||
supplied, or a `meta.json` is found in the input directory, this file is used.
|
||
Otherwise, the data can be entered directly from the command line. spaCy will
|
||
then create a `.tar.gz` archive file that you can distribute and install with
|
||
`pip install`.
|
||
|
||
<Infobox title="New in v3.0" variant="warning">
|
||
|
||
The `spacy package` command now also builds the `.tar.gz` archive automatically,
|
||
so you don't have to run `python setup.py sdist` separately anymore.
|
||
|
||
</Infobox>
|
||
|
||
```bash
|
||
$ python -m spacy package [input_dir] [output_dir] [--meta-path] [--create-meta]

|
||
|
||
| Argument | Type | Description |
|
||
| ------------------------------------------------ | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||
| `input_dir` | positional | Path to directory containing model data. |
|
||
| `output_dir` | positional | Directory to create package folder in. |
|
||
| `--meta-path`, `-m` <Tag variant="new">2</Tag> | option | Path to `meta.json` file (optional). |
|
||
| `--create-meta`, `-c` <Tag variant="new">2</Tag> | flag | Create a `meta.json` file on the command line, even if one already exists in the directory. If an existing file is found, its entries will be shown as the defaults in the command line prompt. |
|
||
| `--version`, `-v` <Tag variant="new">3</Tag> | option | Package version to override in meta. Useful when training new versions, as it doesn't require editing the meta template. |
|
||
| `--force`, `-f` | flag | Force overwriting of existing folder in output directory. |
|
||
| `--help`, `-h` | flag | Show help message and available arguments. |
|
||
| **CREATES** | directory | A Python package containing the spaCy model. |
|
||
|
||
## Project {#project new="3"}
|
||
|
||
The `spacy project` CLI includes subcommands for working with
|
||
[spaCy projects](/usage/projects), end-to-end workflows for building and
|
||
deploying custom spaCy models.
|
||
|
||
### project clone {#project-clone}
|
||
|
||
Clone a project template from a Git repository. Calls into `git` under the hood
|
||
and uses the sparse checkout feature, so you're only downloading what you need.
|
||
By default, spaCy's
|
||
[project templates repo](https://github.com/explosion/projects) is used, but you
|
||
can provide any other repo (public or private) that you have access to using the
|
||
`--repo` option.
|
||
|
||
<!-- TODO: update example once we've decided on repo structure -->
|
||
|
||
```bash
|
||
$ python -m spacy project clone [name] [dest] [--repo]
|
||
```
|
||
|
||
> #### Example
|
||
>
|
||
> ```bash
|
||
> $ python -m spacy project clone some_example
|
||
> ```
|
||
>
|
||
> Clone from custom repo:
|
||
>
|
||
> ```bash
|
||
> $ python -m spacy project clone template --repo https://github.com/your_org/your_repo
|
||
> ```
|
||
|
||
| Argument | Type | Description |
|
||
| -------------- | ---------- | ---------------------------------------------------------------------------------------------------------------------------- |
|
||
| `name` | positional | The name of the template to clone, relative to the repo. Can be a top-level directory or a subdirectory like `dir/template`. |
|
||
| `dest` | positional | Where to clone the project. Defaults to current working directory. |
|
||
| `--repo`, `-r` | option | The repository to clone from. Can be any public or private Git repo you have access to. |
|
||
| `--help`, `-h` | flag | Show help message and available arguments. |
|
||
| **CREATES** | directory | The cloned [project directory](/usage/projects#project-files). |
|
||
|
||
### project assets {#project-assets}
|
||
|
||
Fetch project assets like datasets and pretrained weights. Assets are defined in
|
||
the `assets` section of the [`project.yml`](/usage/projects#project-yml). If a
|
||
`checksum` is provided, the file is only downloaded if no local file with the
|
||
same checksum exists and spaCy will show an error if the checksum of the
|
||
downloaded file doesn't match. If assets don't specify a `url` they're
|
||
considered "private" and you have to take care of putting them into the
|
||
destination directory yourself. If a local path is provided, the asset is copied
|
||
into the current project.
|
||
|
||
```bash
|
||
$ python -m spacy project assets [project_dir]
|
||
```
|
||
|
||
> #### Example
|
||
>
|
||
> ```bash
|
||
> $ python -m spacy project assets
|
||
> ```
|
||
|
||
| Argument | Type | Description |
|
||
| -------------- | ---------- | ----------------------------------------------------------------- |
|
||
| `project_dir` | positional | Path to project directory. Defaults to current working directory. |
|
||
| `--help`, `-h` | flag | Show help message and available arguments. |
|
||
| **CREATES** | files | Downloaded or copied assets defined in the `project.yml`. |
|
||
|
||
### project run {#project-run}
|
||
|
||
Run a named command or workflow defined in the
|
||
[`project.yml`](/usage/projects#project-yml). If a workflow name is specified,
|
||
all commands in the workflow are run, in order. If commands define
|
||
[dependencies or outputs](/usage/projects#deps-outputs), they will only be
|
||
re-run if state has changed. For example, if the input dataset changes, a
|
||
preprocessing command that depends on those files will be re-run.
|
||
|
||
```bash
|
||
$ python -m spacy project run [subcommand] [project_dir] [--force] [--dry]
|
||
```
|
||
|
||
> #### Example
|
||
>
|
||
> ```bash
|
||
> $ python -m spacy project run train
|
||
> ```
|
||
|
||
| Argument | Type | Description |
|
||
| --------------- | ---------- | ----------------------------------------------------------------- |
|
||
| `subcommand` | positional | Name of the command or workflow to run. |
|
||
| `project_dir` | positional | Path to project directory. Defaults to current working directory. |
|
||
| `--force`, `-F` | flag | Force re-running steps, even if nothing changed. |
|
||
| `--dry`, `-D` | flag | Perform a dry run and don't execute scripts. |
|
||
| `--help`, `-h` | flag | Show help message and available arguments. |
|
||
|
||
### project dvc {#project-dvc}
|
||
|
||
Auto-generate [Data Version Control](https://dvc.org) (DVC) config file. Calls
|
||
[`dvc run`](https://dvc.org/doc/command-reference/run) with `--no-exec` under
|
||
the hood to generate the `dvc.yaml`. A DVC project can only define one pipeline,
|
||
so you need to specify one workflow defined in the
|
||
[`project.yml`](/usage/projects#project-yml). If no workflow is specified, the
|
||
first defined workflow is used. The DVC config will only be updated if the
|
||
`project.yml` changed. For details, see the
|
||
[DVC integration](/usage/projects#dvc) docs.
|
||
|
||
<Infobox variant="warning">
|
||
|
||
This command requires DVC to be installed and initialized in the project
|
||
directory, e.g. via [`dvc init`](https://dvc.org/doc/command-reference/init).
|
||
You'll also need to add the assets you want to track with
|
||
[`dvc add`](https://dvc.org/doc/command-reference/add).
