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 spacy --help].
+h(3, "download") Download
p
| Download #[+a("/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("/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", "$").

+aside("Downloading best practices")
| The #[code 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 #[strong not recommended]
| to use this command as part of an automated process. If you know which
| model your project needs, you should consider a
| #[+a("/usage/models#download-pip") 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.
+h(3, "link") Link
p
| Create a #[+a("/usage/models#usage") shortcut link] for a model,
| either a Python package or a local directory. This will let you load
| models from any location using a custom name via
| #[+api("spacy#load") #[code spacy.load()]].
+infobox("Important note")
| In spaCy v1.x, you had to use the model data directory to set up a shortcut
| link for a local path. As of v2.0, spaCy expects all shortcut links to
| be #[strong loadable model packages]. If you want to load a data directory,
| call #[+api("spacy#load") #[code spacy.load()]] or
| #[+api("language#from_disk") #[code Language.from_disk()]] with the path,
| or use the #[+api("cli#package") #[code package]] command to create a
| model package.
