`mostSimilar` outputs numbers when using Fasttext word vectors

[please-wait]

Hi,

First of all, thanks for the awesome work!

I am trying to import the pre-trained files from the fasttext repo: https://github.com/facebookresearch/fastText/blob/master/pretrained-vectors.md

The model loads without a problem; however, when I try mostSimilar, the most similar words appear to be numbers:

loadedModel.mostSimilar('hi')

I also tried hello it says it is out of the dictionary. How can I import the Fasttext files so that this won't happen?

Hello,

I faced a similar issue when using another pre-trained file. The problem was that loadModel read the model file as a binary file although it's actually a plain text.

loadModel distinguishes whether the model file is binary using mime.lookup(file). I fixed the problem by changing the extension of the model file from .bin to .txt.

Thanks a lot @pizzacat83 for sharing your solution. I'll give it a try as soon as I can.
