Gensim Fasttext Cannot Get Latest Training Loss

Problem description It seems that the get_latest_training_loss function in fasttext returns only 0. Both gensim 4.1.0 and 4.0.0 do not work. from gensim.models.callbacks import Cal

Solution 1:

Indeed, loss-tracking hasn't ever been implemented in Gensim's FastText model, at least through release 4.1.0 (August 2021).

The docs for that method appear in error, due to the inherited method from the Word2Vec superclass not being overriden to prevent the default assumption that superclass methods work.

There is a long-open issue to fill the gaps & fix the problems in Gensim's loss-tracking (which is also somewhat buggy & incomplete for Word2Vec). But, at the moment I don't think any contributor is working on it, & it hasn't been prioritized for any upcoming release. It may require someone to volunteer to step forward & fix things.
