Programmatically install NLTK corpora / models, i.e. without the GUI downloader?

Question

My project uses the NLTK. How can I list the project\'s corpus & model requirements so they can be automatically installed? I don\'t want to click through the nltk

Answer 1

To install all NLTK corpora & models:

python -m nltk.downloader all

Alternatively, on Linux, you can use:

sudo python -m nltk.downloader -d /usr/local/share/nltk_data all

Replace all by popular if you just want to list the most popular corpora & models.

---

You may also browse the corpora & models through the command line:

mlee@server:/scratch/jjylee/tests$ sudo python -m nltk.downloader
[sudo] password for jjylee:
