Init-model doeesn't work for some languages

[Xargonus]

Init-model doesn't work for some languages with less features. So far I have found that cs and bg don't work, but there are probably more. The problem is I think init-model expecting non-empty vocab.

Error

python -m spacy init-model bg test
�[2K✔ Counted frequencies

0it [00:00, ?it/s]

How to reproduce the behaviour

python -m spacy init-model cs test

Thanks for the report – fixed in #4048.

In the meantime, if you just want an empty blank model saved to a directory (no vectors etc.), you can also use this one-liner:

python -c "import spacy;spacy.blank('cs').to_disk('/path/to/model')"
