Introducing a library that was not included in pip on Python / Windows

Introduction

I had a hard time installing scikit-learn and Gensim, which are essential for machine learning and natural language processing, with pip, so I will summarize how to install libraries that could not be installed with pip.

My environment

OS: Windows 7 64bit python:python 3.4.3　64bit

procedure

  1. Python version, bit check
  2. Introduce wheel
  3. Download the library you want to include
  4. Library introduction
  5. Done

Python version, bit check

Run python on the command prompt and check the result Example Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 64 bit (AMD64)] on win32 → python3.4.3 64bit

Introduced wheel

Execute the following command pip install wheel-0.24.0.tar.gz

I was allowed to reference Mastering pip and wheel on windows http://qiita.com/toruuetani/items/b0000e9f5c89a350d4f8

Download the library you want to include

Unofficial Windows Binaries for Python Extension Packages http://www.lfd.uci.edu/~gohlke/pythonlibs/

Find the library you want to include from the page above and download the one that suits your environment

Example I downloaded "scikit_learn-0.16.1-cp34-none-win_amd64.whl" because the version of python is 3.4 series, 64bit. cp34 → Python version amd64 → Python bit number

scikit_learn-0.16.1-cp34-none-win_amd64.whl 　　　　　　　　　　　　　↑python　　　　　↑bit

Library introduction

Place the downloaded whl in C: \ Python \ Scripts At the command prompt: cd C:\Python\Scripts pip install example.whl

Done

I think I was able to introduce it with this By default, python is installed in 32bit, which is a stumbling block.
