How to add fastText pre-trained/customized word embedding in RASA NLU? I’m trying to make a chatbot for ‘Bangla’ Language.

Hey @nurakib. I think this thread will be helpful for you: [Feeding Custom/Pretrained embeddings for ner\_crf](http://forum.rasa.com/t/feeding-custom-pretrained-embeddings-for-ner-crf/5406). Our contributor Souvik wrote a great tutorial on how to use fastText with Rasa, have a look and let us know if you need more help.

This works slightly more simply than that post now.

Once you convert the `fastText` model to `spacy` vectors, you can just add `text_dense_features` under `CRFEntityExtractor`'s features, and your `SpacyFeaturizer` will add a dense vector per token.

The article in the medium about using fasttext is quite confusing, can I get some steps to do the same for other languages than English?.

Hi @Shrivatsa2904. I would suggest checking out one of our latest projects - [Rasa NLU examples](https://blog.rasa.com/introducing-rasa-nlu-examples/) where you can also find components that support other languages as well.
