How to slove this Q?

[NehKulkarni]

Download the pyFM project
After installing Visual C++ Build Tools, do the following:
Remove the parameter : libraries=["m"] in the setup.py file and save it
Run the setup.py using : python setup.py install

It worked for me.. hope it helps! :)

need more details @NehKulkarni

[NehKulkarni]

@tiancaipipi110 Please make sure that your setup.py file looks like this:

setup(
maintainer='Corey Lynch',
name='pyfm',
packages=find_packages(),
url='https://github.com/coreylynch/pyFM',
cmdclass = {'build_ext': build_ext},
ext_modules = [Extension("pyfm_fast", ["pyfm_fast.pyx"],
include_dirs=[numpy.get_include()])]
)

We just need to remove the libraries=["m"] parameter from it.
Hope this helps! :)

For people coming from different languages - would be good if you could add more details like - where to edit this file or what is the location of this file?
