include ../../_includes/_mixins

p
    |  As of v1.7.0, spaCy comes with new command line helpers to download and
    |  link models and show useful debugging information. For a list of available
    |  commands, type #[code python -m spacy --help].

+aside("Why python -m?")
    |  The problem with a global entry point is that it's resolved by looking up
    |  entries in your #[code PATH] environment variable. This can give you
    |  unexpected results, like executing the wrong spaCy installation
    |  (especially when using #[code virtualenv]). #[code python -m] prevents
    |  fallbacks to system modules and makes sure the correct spaCy version is
    |  used. If you hate typing it every time, we recommend creating an
    |  #[code alias] instead.

+h(2, "download") Download

p
    |  Download #[+a("/docs/usage/models") models] for spaCy. The downloader finds the
    |  best-matching compatible version, uses pip to download the model as a
    |  package and automatically creates a
    |  #[+a("/docs/usage/models#usage") shortcut link] to load the model by name.
    |  Direct downloads don't perform any compatibility checks and require the
    |  model name to be specified with its version (e.g., #[code en_core_web_sm-1.2.0]).

+code(false, "bash").
    python -m spacy download [model] [--direct]

+h(2, "link") Link

p
    |  Create a #[+a("/docs/usage/models#usage") shortcut link] for a model,
    |  either a Python package or a local directory. This will let you load

    |  #[+api("spacy#load") #[code spacy.load()]].
