"Language is not supported."

[tezer]

Hi
I am trying to use Wordnet for Finnish, but it looks like there is no Finnish data downloaded with the package.
This code produces an error below.

from wn import WordNet
from wn.constants import wordnet_30_dir
fin_wn = WordNet(wordnet_30_dir)
print(fin_wn.langs())
fin_wn.synsets(lemma, lang=lang)

4135382db444:python -u /opt/project/task_generation/generator.py
['eng']
Traceback (most recent call last):
  File "/opt/project/task_generation/generator.py", line 18, in <module>
    search_wn('cat', 'n', 'fin')
  File "/opt/project/task_generation/generator.py", line 10, in search_wn
    res = fin_wn.synsets(lemma, lang=lang)
  File "/usr/local/lib/python3.8/site-packages/wn/__init__.py", line 154, in synsets
    self._load_lang_data(lang)
  File "/usr/local/lib/python3.8/site-packages/wn/omw.py", line 79, in _load_lang_data
    raise WordNetError("Language is not supported.")
NameError: name 'WordNetError' is not defined

Do I need to install language-specific packages separately?

@tezer I think the wordnet_30_dir is for the Princeton WordNet 3.0, which is just English. The Open Multilingual Wordnet (OMW) is what you want, so use the omw_dir variable instead. Also note that this project is not being maintained, so you might have better luck with https://github.com/goodmami/wn/ (disclaimer: I'm the author). Here's an example (using that project) to download and use the Finnish wordnet:

>>> import wn
>>> wn.download('finwn')
[...]
>>> for w in wn.words(lang='fi')[:10]:
...     print(w.lemma())
