Error while loading French binary model

[qdHe]

I download pretrained fasttext models of English and French from https://fasttext.cc/docs/en/pretrained-vectors.html. When I use load_facebook_model() function to load the data, wiki.en.bin goes well but wiki.fr.bin cannot be loaded. The error is

Traceback (most recent call last):

I do not think only the French model is supervised. Is there any bug? If it is not a bug in gensim, I guess there is some problem in the model. With a closer look, I find that the value of nwords and the size of vocabulary is 1152450, while the size of vectors is 1152449. I am not sure what is the reason of this mismatch. @cpuhrsch

@qdHe - I am not working on fastText anymore, please refer to the current maintainers possibly based on recent commits over at the main repository.
