Fasttext: Python fasttext build failure

[shriiitk]

I executed python setup.py install but it is failing with these errors:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.12.25827\Include\numeric(13): note: see declaration of 'std' src\productquantizer.cc(132): error C3861: 'to_string': identifier not found src\productquantizer.cc(132): error C2512: 'std::invalid_argument': no appropriate default constructor available src\productquantizer.cc(132): note: No constructor could take the source type, or constructor overload resolution was ambiguous error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\VC\\Tools\\MSVC\\14.12.25827\\bin\\HostX64\\x64\\cl.exe' failed with exit status 2

I am running Python 3.6.2 :: Anaconda custom (64-bit) on Windows 10 desktop. Do I need specific version of visual studio or build tools?

First add #include <string> in src\productquantizer.cc, after that you will probably get LNK1104: can not open file 'pthread.lib' error. To resolve this remove -pthread flag from extra_compile_args in setup.py L62. Now simple pip install . will work just fine (I'm on Windows 10, VS Community 2017 and Python 3.6.3 | Anaconda custom (64-bit))

Thanks @suamin adding #include <string> worked. I don't know how they missed it.
