`available_uriel_languages` is not correct

[matus-pikuliak]

I've noticed that available_uriel_languages does not work properly. I am not sure why it is filtered according to fam features, but the filtering itself seems buggy. The resulting mask has only ~3.5k elements, even though we have 7k languages with URIEL features. All of elements in the mask are True. Additionally, the number 3.5k is exactly equal to the number of language families. I suspect that the reduction in np.all might being done along wrong axis.

I have sidestepped the issue for now by using data directly from the feature_predictions.npz file.

lang2vec/lang2vec/lang2vec.py

Lines 57 to 69 in 82ab445

	def available_uriel_languages():
	avail = set()
	#for feature_set in FEATURE_SETS_DICT:
	for feature_set in ["fam"]:
	filename, source, prefix = FEATURE_SETS_DICT[feature_set]
	filename = pkg_resources.resource_filename(__name__, os.path.join('data', filename))
	feature_database = np.load(filename)
	mask = np.all(feature_database["data"] != -1.0, axis=0)
	langs = [feature_database["langs"][i] for i,m in enumerate(mask) if np.sum(m)>0]
	for l in langs:
	avail.add(l)
	return avail

Huh, thanks! I'll look into incorporating this.
