설치전 끝까지 읽어보시기 바랍니다.
아래 글을 보고
https://xgboost.readthedocs.io/en/latest/build.html
환경 : python 3.6.4, 32 bit 환경, windows 에서 설치 시작해 보았습니다.

뭔가 이상한 오류가 발생합니다.
그래서 검색해보니 환경마다 다른 특정 파일을 다운로드 필요하다고 합니다.
좋은글을 발견
1. 다음 링크에서 적당한 파일 다운로드
https://www.lfd.uci.edu/~gohlke/pythonlibs/
(3.6버전에 32bit 환경이라 다음 파일 다운로드)
xgboost‑0.81‑cp36‑cp36m‑win32.whl
2. 다음 명령으로 설치
pip install [whl파일명](py364_env) E:\Program Files (x86)\Python36-32>pip install C:\Users\darts\Downloads\xgboost-0.81-cp36-cp36m-win32.whl

4. 동작확인
설치는 된것 같은데 동작이 제대로 안됩니다.(py364_env) E:\Program Files (x86)\Python36-32\py364_env\Scripts>python

5. 다시 원점으로
64 bit windows에서는 64 bit Python을 설치하여야 한다고 하네요이번엔 anaconda 환경에서 설치 64 bit anaconda python 3.7 버전으로 시도
6. 다운로드
https://www.lfd.uci.edu/~gohlke/pythonlibs/ 여기에서 아래 파일 다운로드xgboost-0.81-cp37-cp37m-win_amd64.whl
7. pip install
(base) C:\Users\xxx>python Python 3.7.1 (default, Dec 10 2018, 22:54:23) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32 Type "help", "copyright", "credits" or "license" for more information. >>> ^Z (base) C:\Users\xxx>pip install C:\Users\darts\Downloads\xgboost-0.81-cp37-cp37m-win_amd64.whl Processing c:\users\darts\downloads\xgboost-0.81-cp37-cp37m-win_amd64.whl Requirement already satisfied: numpy in e:\programdata\anaconda3\lib\site-packages (from xgboost==0.81) (1.15.4) Requirement already satisfied: scipy in e:\programdata\anaconda3\lib\site-packages (from xgboost==0.81) (1.1.0) Installing collected packages: xgboost Successfully installed xgboost-0.81
8. 제대로 설치되었는지 확인

9. 결론
- 64 bit 윈도우에서는 64bit용 python 설치 필요- https://www.lfd.uci.edu/~gohlke/pythonlibs/ 여기에서 운영체제와 python 버전이 맞는 파일을 다운로드
- pip install whl파일
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10. 시간이 흘러 2020.08.23일
Python 3.6 64bit windows환경 에서 간단하게 pip로 간단하게 설치 가능합니다.
