Downloading Models
==================
Polyglot requires a model for each task and language. These models are
essential for the library to function. Given the large size of some of
the models, we distribute the models through a download manager
separately. The download manager has several modes of operation.
Modes of Operation
------------------
Command Line Mode
~~~~~~~~~~~~~~~~~
The subcommand ``download`` takes a package or more as an argument and
download the specified packages in the ``polyglot_data`` directory.
.. code:: python
!polyglot download --help
.. parsed-literal::
usage: polyglot download [-h] [--dir DIR] [--quiet] [--force] [--exit-on-error] [--url SERVER_INDEX_URL] [packages [packages ...]]
positional arguments:
packages packages to be downloaded
optional arguments:
-h, --help show this help message and exit
--dir DIR download package to directory DIR
--quiet work quietly
--force download even if already installed
--exit-on-error exit if an error occurs
--url SERVER_INDEX_URL
download server index url
.. code:: python
!polyglot download morph2.en
.. parsed-literal::
[polyglot_data] Downloading package morph2.en to
[polyglot_data] /home/rmyeid/polyglot_data...
[polyglot_data] Package morph2.en is already up-to-date!
Interactive Mode
~~~~~~~~~~~~~~~~
You can reach this mode by not supplying any arguments to the command
line.
.. code:: python
!polyglot download
.. parsed-literal::
Polyglot Downloader
---------------------------------------------------------------------------
d) Download l) List u) Update c) Config h) Help q) Quit
---------------------------------------------------------------------------
Downloader>
Library Interface
~~~~~~~~~~~~~~~~~
.. code:: python
from polyglot.downloader import downloader
downloader.download("embeddings2.en")
Collections
-----------
You noticed, by now, that we can install a specific model by specifying
its name and the target language.
Package name format is ``task_name.language_code``
Langauge Collections
^^^^^^^^^^^^^^^^^^^^
Packages are grouped by language. For example, if we want to download
all the models that are specific to Arabic, the arabic collection of
models name is **LANG:** followed by the language code of Arabic which
is ``ar``.
Therefore, we can just run:
.. code:: python
!polyglot download LANG:ar
.. parsed-literal::
[polyglot_data] Downloading collection u'LANG:ar'
[polyglot_data] |
[polyglot_data] | Downloading package tsne2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package tsne2.ar is already up-to-date!
[polyglot_data] | Downloading package transliteration2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package transliteration2.ar is already up-to-
[polyglot_data] | date!
[polyglot_data] | Downloading package morph2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package morph2.ar is already up-to-date!
[polyglot_data] | Downloading package counts2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package counts2.ar is already up-to-date!
[polyglot_data] | Downloading package sentiment2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package sentiment2.ar is already up-to-date!
[polyglot_data] | Downloading package embeddings2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package embeddings2.ar is already up-to-date!
[polyglot_data] | Downloading package ner2.ar to
[polyglot_data] | /home/rmyeid/polyglot_data...
[polyglot_data] | Package ner2.ar is already up-to-date!
[polyglot_data] |
[polyglot_data] Done downloading collection LANG:ar
Task Collections
^^^^^^^^^^^^^^^^
Packages are grouped by task. For example, if we want to download all
the models that perform transliteration. The collection name is
**TASK:** followed by the task name.
Therefore, we can just run:
.. code:: python
downloader.download("TASK:transliteration2", quiet=True)
.. parsed-literal::
True
Langauge & Task Support
-----------------------
We can query our download manager for which tasks are supported by
polyglot, as the following:
.. code:: python
downloader.supported_tasks(lang="en")
.. parsed-literal::
[u'embeddings2',
u'counts2',
u'pos2',
u'ner2',
u'sentiment2',
u'morph2',
u'tsne2']
We can query our download manager for which languages are supported by
polyglot named entity recognition subsystem, as the following:
.. code:: python
print(downloader.supported_languages_table(task="ner2"))
.. parsed-literal::
1. Polish 2. Turkish 3. Russian
4. Indonesian 5. Czech 6. Arabic
7. Korean 8. Catalan; Valencian 9. Italian
10. Thai 11. Romanian, Moldavian, ... 12. Tagalog
13. Danish 14. Finnish 15. German
16. Persian 17. Dutch 18. Chinese
19. French 20. Portuguese 21. Slovak
22. Hebrew (modern) 23. Malay 24. Slovene
25. Bulgarian 26. Hindi 27. Japanese
28. Hungarian 29. Croatian 30. Ukrainian
31. Serbian 32. Lithuanian 33. Norwegian
34. Latvian 35. Swedish 36. English
37. Greek, Modern 38. Spanish; Castilian 39. Vietnamese
40. Estonian
You can view all the available and/or installed collections or packages
through the list function
.. code:: python
downloader.list(show_packages=False)
.. parsed-literal::
