For a list of available commands, type spacy --help.

Download

Download 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, 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.

$ python -m spacy download [model] [--direct] [pip args]

Argument	Type	Description
model	positional	Model name, e.g. en_core_web_sm..
--direct, -d	flag	Force direct download of exact model version.
pip args 2.1	-	Additional installation options to be passed to pip install when installing the model package. For example, --user to install to the user home directory or --no-deps to not install model dependencies.
--help, -h	flag	Show help message and available arguments.
CREATES	directory	The installed model package in your site-packages directory.

Info

Print information about your spaCy installation, models and local setup, and generate Markdown-formatted markup to copy-paste into GitHub issues.

$ python -m spacy info [--markdown] [--silent]

$ python -m spacy info [model] [--markdown] [--silent]

Argument	Type	Description
model	positional	A model, i.e. package name or path (optional).
--markdown, -md	flag	Print information as Markdown.
--silent, -s 2.0.12	flag	Don't print anything, just return the values.
--help, -h	flag	Show help message and available arguments.
PRINTS	stdout	Information about your spaCy installation.

Validate

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 If any model is out of date, the latest compatible versions and command for updating are shown.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.

$ python -m spacy validate

Argument	Type	Description
PRINTS	stdout	Details about the compatibility of your installed models.

Convert

Convert files into spaCy's binary training data format, a serialized 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.

$ python -m spacy convert [input_file] [output_dir] [--converter]

Pretrain

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. However, it's still quite experimental, so your mileage may vary. To load the weights back in during spacy train, you need to ensure all settings are the same between pretraining and training. The API and errors around this need some improvement.

JSONL format for raw text

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 provides a handy write_jsonl helper that takes a file path and list of dictionaries and writes out JSONL-formatted data.

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.

### 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

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 as --jsonl-loc with optional id values that correspond to the vectors table. Just loading in vectors will not automatically populate the vocab.

$ python -m spacy init-model [lang] [output_dir] [--jsonl-loc] [--vectors-loc]
[--prune-vectors]

Argument	Type	Description
lang	positional	Model language ISO code, 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 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 2.3	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 2.3	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 a model's accuracy and speed on JSON-formatted annotated data. Will print the results and optionally export displaCy visualizations 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.

$ python -m spacy evaluate [model] [data_path] [--displacy-path] [--displacy-limit]
[--gpu-id] [--gold-preproc] [--return-scores]

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 JSON-formatted evaluation data.
--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.
--return-scores, -R	flag	Return dict containing model scores.
CREATES	stdout, HTML	Training results and optional displaCy visualizations.

Package

Generate an installable model Python package 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.

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.

$ python -m spacy package [input_dir] [output_dir] [--meta-path] [--create-meta] [--force]

### Example
python -m spacy package /input /output
cd /output/en_model-0.0.0
pip install dist/en_model-0.0.0.tar.gz

Argument	Type	Description
input_dir	positional	Path to directory containing model data.
output_dir	positional	Directory to create package folder in.
--meta-path, -m 2	option	Path to meta.json file (optional).
--create-meta, -c 2	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 3	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.
