setup fails when Cython is not available

[ink1]

Hi, in your setup, you are trying to handle a case when Cython is not available but it does not work so you should either put Cython as a dependency and throw an error or provide the missing file. https://github.com/glample/fastBPE/blob/1fd33189c126dae356b9e187d93d93302fa45cef/setup.py#L6 If Cython is missing then

extension = 'cpp'

which leads to "fastBPE/fastBPE." + extension but there is no fastBPE/fastBPE.cpp file.

Ah, this file is provided in the package on pypi, but not distributed in the source on github. Can you install Cython and build that way?

Hi, yes, that exactly what i had done.
