| pip and virtualenv
|
||
|
||
p.
|
||
With Python 2.7 or Python 3, using Linux or OSX, ensure that you have
|
||
the packages #[code build-essential] and #[code python-dev] installed.
|
||
Then run:
|
||
|
||
+code('bash').
|
||
pip install spacy
|
||
python -m spacy.en.download
|
||
|
||
p.
|
||
The download command fetches and installs about 500mb of data, for the
|
||
parser model and word vectors, which it installs within the spacy
|
||
package directory. Usually you'll want to install spaCy within a
|
||
#[a(href='https://virtualenv.readthedocs.org/en/latest/' target='_blank') virtualenv],
|
||
to avoid modifying system state:
|
||
|
||
+code('bash').
|
||
virtualenv my_env_dir
|
||
source my_env_dir/bin/activate
|
||
|
||
+section('install-conda')
|
||
+h3('install-conda')
|
||
| conda
|
||
|
||
+code('bash').
|
||
conda config --add channels spacy
|
||
conda install spacy
|
||
python -m spacy.en.download
|
||
|
||
p.
|
||
Sometimes conda is not up to date with the latest release. If you
|
||
can't get the latest version on conda, you can always fall back to the
|
||
pip install.
|
||
|
||
+section('install-windows')
|
||
+h3('install-windows')
|
||
| Windows (64 bit)
|
||
|
||
p.
|
||
We've been working on Windows support. Our tests now succeed on 64 bit
|
||
builds of Windows. Installation from pip should work if you have a C++
|
||
compiler installed. Please see the README-MSVC.txt file for instructions
|
||
on compiling from source.
|
||
|
||
+section('install-update')
|
||
+h3('install-update')
|
||
| Updating your installation
|
||
|
||
p.
|
||
To update your installation:
|
||
|
||
+code('bash').
|
||
pip install --upgrade spacy
|
||
python -m spacy.en.download
|
||
|
||
p.
|
||
Most updates ship a new model, so you will usually have to redownload
|
||
the data.

| Workaround for obsolete system Python
|
||
|
||
p.
|
||
If you're stuck using a server with an old version of Python, and you
|
||
don't have root access, we've prepared a bootstrap script to help you
|
||
compile a local Python install. Run:
|
||
|
||
+code('bash')
|
||
curl https://raw.githubusercontent.com/spacy-io/gist/master/bootstrap_python_env.sh | bash && source .env/bin/activate
|
||
|
||
+section('install-compile')
|
||
+h3('install-compile')
|
||
| Compile from source
|
||
|
||
p.
|
||
The other way to install the package is to clone the github repository,
|
||
and build it from source. This installs an additional dependency, Cython.
|
||
If you're using Python 2, we also recommend installing fabric and
|
||
fabtools – this is how we build the project. Ensure that you have the
|
||
packages #[code build-essential], #[code python-dev], #[code git] and
|
||
#[code python-virtualenv] installed.
|
||
|
||
+code('bash')
|
||
git clone https://github.com/spacy-io/spaCy.git
|
||
cd spaCy
|
||
virtualenv .env && source .env/bin/activate
|
||
pip install -r requirements.txt
|
||
pip install -e .
|
||
python -m spacy.en.download
|
||
pip install pytest
|
||
python -m pytest spacy
|
||
|
||
p.
|
||
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.

||
|
||
+section('install-pypy')
|
||
+h3('install-pypy')
|
||
| pypy (unsupported)
|
||
|
||
p.
|
||
If PyPy support is a priority for you, please get in touch. We could
|
||
likely fix the remaining issues, if necessary. However, the library
|
||
is likely to be much slower on PyPy, as it's written in Cython, which
|
||
produces code tuned for the performance of CPython.
