note: This error originates from a subprocess, and is likely not a problem with pip.

OpenFST Installation Error on Windows With pip

I want to use openfst python wrapper on my python application.
When I run
pip install openfst
for Python 3.6 gave error as the following.
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\Users\aliye\Anaconda3\include -IC:\Users\aliye\Anaconda3\include "-IC:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE" "-IC:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\ucrt" "-IC:\Program Files (x86)\Windows Kits\8.1\include\shared" "-IC:\Program Files (x86)\Windows Kits\8.1\include\um" "-IC:\Program Files (x86)\Windows Kits\8.1\include\winrt" /EHsc /Tppywrapfst.cc /Fobuild\temp.win-amd64-3.6\Release\pywrapfst.obj -std=c++11 -Wno-unneeded-internal-declaration -Wno-unused-function

Obviously, it looks like the Visual Studio compiler is complaining about /Wno-unneeded-internal-declaration flag while it is trying to build the C extensions.
The easiest solution would be to download a pre-compiled version that matches your system at their website
Also, based on their site, it seems that they used Visual Studio 2013.You may be able to install and compile it using VS13.

Compiling with Cython on Windows: missing source filename

I'm trying to compile a hello world example with Cython on Windows 10.
I have visual studio 2015 community.
Python 3.5.2
My setup.py looks like this:
from distutils.core import setup
from Cython.Build import cythonize
setup (
name='print hello world',
ext_modules=cythonize("print_h_w.pyx", compiler_directives=
{'language_level': 3}),
)
The file I'm trying to compile looks like this:
print('Hello World')
I build with this command:
python setup.py build_ext --inplace
I keep getting this error:

I've been doing a lot of research but I've turned up a lot of nothing. How can I fix this?

I think you should have import cython in your print_h_w.pyx file :
import cython
print("hello world")

The problem seems to be the same, any ideas ?

SOLVED. I had to download this and unzip to c:\
See https://github.com/mrjbq7/ta-lib#dependencies

Download file TA_Lib-0.4.24-cp37-cp37m-win_amd64.whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib
then use pip install TA_Lib-0.4.24-cp37-cp37m-win_amd64.whl
