Install spaCy
|
||||
=============
|
||||
|
||||
spaCy is compatible with 64-bit CPython 2.6+/3.3+ and runs on Unix/Linux, OS X
|
||||
and Windows. Source packages are available via
|
||||
`pip <https://pypi.python.org/pypi/spacy>`_. Please make sure that
|
||||
you have a working build enviroment set up. See notes on Ubuntu, macOS/OS X and Windows
|
||||
for details.

`pip <https://pypi.python.org/pypi/spacy>`_ (source packages only) and

When using pip it is generally recommended to install packages in a virtualenv to
|

avoid modifying system state:

Using pip, spaCy releases are currently only available as source packages.

|

.. code:: bash

pip install spacy
|
||||
pip install -U spacy
|
||||
|
||||
Python packaging is awkward at the best of times, and it's particularly tricky with
|
||||
C extensions, built via Cython, requiring large data files. So, please report issues
|
||||
as you encounter them.

English and German, named ``en`` and ``de``, are available.

Upgrading spaCy
|
||||
===============

||||
|
||||
To upgrade spaCy to the latest release:
|
||||
|
||||
pip
|
||||
---
|
||||
|
||||
.. code:: bash
|
||||
|
||||
pip install -U spacy
|
||||
|
||||
Sometimes new releases require a new language model. Then you will have to upgrade to
|
||||
a new model, too. You can also force re-downloading and installing a new language model:
|
||||
Sometimes new releases require a new language model. Then you will have to
|
||||
upgrade to a new model, too. You can also force re-downloading and installing a
|
||||
new language model:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
python -m spacy.en.download --force
|
||||
|
||||
Download model to custom location
|
||||
---------------------------------
|
||||
|
||||
You can specify where ``spacy.en.download`` and ``spacy.de.download`` download
|
||||
the language model to using the ``--data-path`` or ``-d`` argument:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
python -m spacy.en.download all --data-path /some/dir
|
||||
|
||||
If you choose to download to a custom location, you will need to tell spaCy where to load the model
|
||||
from in order to use it. You can do this either by calling ``spacy.util.set_data_path()`` before
|
||||
calling ``spacy.load()``, or by passing a ``path`` argument to the ``spacy.en.English`` or
|
||||
``spacy.de.German`` constructors.
|
||||
|
||||
Download models manually
|
||||
------------------------
|
||||
|
||||
As of v1.6, the models and word vectors are also available as direct downloads
|
||||
from GitHub, attached to the `releases <https://github.com/explosion/spacy/releases>`_
|
||||
as ``.tar.gz`` archives.
|
||||
|
||||
To install the models manually, first find the default data path. You can use
|
||||
``spacy.util.get_data_path()`` to find the directory where spaCy will look for
|
||||
its models, or change the default data path with ``spacy.util.set_data_path()``.
|
||||
Then simply unpack the archive and place the contained folder in that directory.
|
||||
You can now load the models via ``spacy.load()``.
|
||||
|
||||

||||

You'll need to make sure that you have a development enviroment consisting of a
|
||||
Python distribution including header files, a compiler, pip, virtualenv and git
|

installed. The compiler part is the trickiest. How to do that depends on your

system. See notes on Ubuntu, OS X and Windows for details.

Instead of the above verbose commands, you can also use the following
|
||||
`Fabric <http://www.fabfile.org/>`_ commands:
|
||||
|
||||
+---------------+--------------------------------------------------------------+
|
||||
| ``fab env`` | Create ``virtualenv`` and delete previous one, if it exists. |
|
||||
+---------------+--------------------------------------------------------------+
|
||||
| ``fab make`` | Compile the source. |
|
||||
+---------------+--------------------------------------------------------------+
|
||||
| ``fab clean`` | Remove compiled objects, including the generated C++. |
|
||||
+---------------+--------------------------------------------------------------+
|
||||
| ``fab test`` | Run basic tests, aborting after first failure. |
|
||||
+---------------+--------------------------------------------------------------+
|
||||
|
||||
All commands assume that your ``virtualenv`` is located in a directory ``.env``.
|
||||
If you're using a different directory, you can change it via the environment
|
||||
variable ``VENV_DIR``, for example:

||||
|
||||
