在python下安装xgboost，32位msys失败

Question

Trying to install xgboost is failing..? The version is Anaconda 2.1.0 (64-bit) on Windows & enterprise. How do I proceed? I have been using R it seems its quite easy to install new package in R from RStudio, but not so in spyder as I need to go to a command-window to do it and then in this case it fails..

import sys

print (sys.version) 
2.7.8 |Anaconda 2.1.0 (64-bit)| (default, Jul  2 2014, 15:12:11) [MSC v.1500 64 bit (AMD64)]

Answer 1

I'm a bit late to answer but I would still go ahead and answer it for anyone who still has an issue with the installation. I followed the steps listed in https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13043/run-xgboost-from-windows-and-python Their is a concise version of these steps at https://github.com/dmlc/xgboost/tree/master/windows . I will summarize what I did below.

1) Download Visual Basic Studio. You can download the community edition at visual studio website. There is a "free visual studio button on the upper right corner"

2) Copy all content from the git hub repository of xgboost/tree/master/windows and Open Visual studio existing project on Visual studio

3) There are a couple of drop down menus you need to select ( "Release" and "X64" and then select build --> build all from the upper menu. It should look something like the attached screenshot.

4) if you see the message ========== Build: 3 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========, it is all good

5) Browse to python-packages folder where the setup file for XGB resides and run the install command 'python setup.py install'.

Hope this helps.

Answer 2

This is an xgboost issue, not an Anaconda issue as you originally tagged (I don't use Anaconda but I got this too).

EDIT: from your updates, your breakage is caused by 32-bit msys somewhere on your path, whereas you have a 64-bit install of Python. Mine and all other people's reported breakage since Aug 25 was the 0.4a12/3 prereleases:

ORIGINAL ANSWER - Based on the limited information you provided (here, as opposed to on the Kaggle thread) and no verbose fail logs: Apparently the latest versions of xgboost on pypi, 0.4a12 and 0.4a13 are both pre-releases, which pip will not use by default, unless you do pip install --pre xgboost .

I found this all out by digging around with pip install -v xgboost , which shows helpful verbose information on why an attempted install failed (below); then use pip help and pip install -h to see all install options:

pip install -v xgboost Downloading/unpacking xgboost   Ignoring link
https://pypi.python.org/packages/source/x/xgboost/xgboost-0.4a12.tar.gz#md5=4d768e034a28590497bb79279f036946
(from https://pypi.python.org/simple/xgboost/), version 0.4a12 is a
pre-release (use --pre to allow).   Ignoring link
https://pypi.python.org/packages/source/x/xgboost/xgboost-0.4a13.tar.gz#md5=5f53d51e4305c679192b3cabda2b0dbe
(from https://pypi.python.org/simple/xgboost/), version 0.4a13 is a
pre-release (use --pre to allow).

Then pip install -h tells you:

Install Options:
  -e, --editable <path/url>   Install a project in editable mode ...
  ...
  --pre                       Include pre-release and development versions. By default, pip only finds stable versions.

And finally:

pip install --pre xgboost

(PS xgboost maintainers made a recent change in Aug 2015 )

Answer 3

This solved my problem

$ sudo apt-get install gcc-5
$ env CC=gcc CXX=g++
$ pip install xgboost

Answer 4

Finally it worked for me (Mac OS) Follow steps below in command prompt:

1. run whole command below "/bin......install.sh) "

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh )"

Note: check this for above command( https://brew.sh/ )

2. brew install libomp

3. pip3 install xgboost
