Python fancyimpute installs on Mac, but not on Windows

Question

I am part of a small team that is trying to install Python's 'fancyimpute' package. Three of us have different Windows machines. One of us has Mac. fancyimpute's page says: 'Operating System :: OS Independent'. My teammate has no problems installing it on his Mac: pip install fancyimpute works as it should.

When we, Windows users, try to do the same, we are getting this error: "error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools"

One we've installed "Visual C++ 2015 Build Tools", we still can't install fancyimpute. The error we are getting is as following:

'NAN'
  ecos/src/ecos.c(1093): warning C4013: '_set_output_format' undefined; assuming extern returning int

  ecos/src/ecos.c(1093): error C2065: '_TWO_DIGIT_EXPONENT': undeclared identifier

  error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2

  Failed building wheel for ecos

Is it possible that it's a hopeless case for Windows machine owners? Or is there a solution?

what is python version ? – Mahesh Karia Nov 06 '17 at 15:38 — Mahesh Karia, Nov 06 '17 at 15:38

I have just installed fancyimpute on windows 10 machine and it was successful. Can you please try running pip command from command prompt in case if you're doing it from pycharm console.

The problem I described happens when we run the pip install command in Anaconda console. I just tried again - same problem. Notice - I am not the only one, 3 of us, with different Windows laptops are having this issue. — user3245256, Nov 06 '17 at 16:08
I also just tried to run pip install fancyimpute in Windows console, but got an error: pip : The term 'pip' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. — user3245256, Nov 06 '17 at 16:08
Are you using python2.7 ? on command prompt if you run `python` then is it recognized ? — Mahesh Karia, Nov 06 '17 at 16:11
We are using Python 3.6.1 installed by Anaconda. When I run just 'python' in Windows PowerShell, I get: the following output: 'Python 3.6.1 |Anaconda custom (64-bit)| (default, May 11 2017, 13:25:24) [MSC v.1900 64 bit (AMD64)] on win32' — user3245256, Nov 06 '17 at 16:18

I found the solution here: Fancyimpute pip install error

Solved the problem by manually downloading the appropriate .whl file (Python version and Windows architecture): Windows binaries

Navigated to the downloaded file (in terminal) and ran pip install filename.whl.
