Failed to install python wrapper on MacOS (python 3) about sentencepiece HOT 6 CLOSED

Python wheel (binary) package is not supported on macOS. It is available for Linux(x64/i686). On macOS, you might need to build SentencePiece C++ library in advance, and then try pip command.

Can report that I'm having problems as well (also on macOS), although pip seems to get farther in OP's case than it does in mine, so perhaps it's unrelated. This is what the output currently looks like:

Yup, that's how I did it in the end. May I suggest adding something to the README that says as much?

Thank you for the suggestion.

Thank you! I didn't install SentencePiece C++ before "python setup.py build". it works correctly

That's a lot clearer, @taku910!

Also, thanks for your work on sentencepiece. Just found out about it today (via https://github.com/bheinzerling/bpemb). It's exactly what I've been looking for :)
