NLTK - Download all nltk data except corpara from command line without Downloader UI

Question

We can download all nltk data using:

> import nltk
> nltk.download('all')

Or specific data using:

> nltk.download('punkt')
> nltk.download('maxent_treebank_pos_tagger')

But I want to download all data except 'corpara' files, for example - all chunkers, grammers, models, stemmers, taggers, tokenizers, etc

is there any way to do so without Downloader UI? something like,

> nltk.download('all-taggers')

Answer 1

List all corpora ids and set _status_cache[pkg.id] = 'installed'.

It will set status value for all corpora as 'installed' and corpora packages will be skipped when we use nltk.download().

Instead of downloading all corpora and models, if you're unsure of which corpora/package you need, use nltk.download('popular').

import nltk

dwlr = nltk.downloader.Downloader()

for pkg in dwlr.corpora():
    dwlr._status_cache[pkg.id] = 'installed'

dwlr.download('popular')

To download all packages of specific folder.

import nltk

dwlr = nltk.downloader.Downloader()

# chunkers, corpora, grammars, help, misc, 
# models, sentiment, stemmers, taggers, tokenizers
for pkg in dwlr.packages():
    if pkg.subdir== 'taggers':
        dwlr.download(pkg.id)
