anaconda 的 xgboost 安装问题

问题描述

我正在使用 Anaconda.我首先切换到 Python2(版本 2.7.11).

I am using Anaconda. I first switched to Python2 (Version 2.7.11).

python -V
Python 2.7.11 :: Continuum Analytics, Inc.

我使用以下命令在 anaconda 中安装 xgboost.

I used the following command to install xgboost in anaconda.

conda install -c https://conda.anaconda.org/akode xgboost

然后我检查了 xgboost 是否已安装.

I then checked that xgboost is installed.

conda list
xgboost                   0.3                      py27_0    akode

我在终端中运行 python，导入 xgboost 并得到以下错误.

I run python in terminal, import xgboost and got the following errors.

import xgboost as xgb

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/envs/wen2/lib/python2.7/site-packages/xgboost.py", line 82, in <module>
    xglib = load_xglib()
  File "//anaconda/envs/wen2/lib/python2.7/site-packages/xgboost.py", line 59, in load_xglib
    lib = ctypes.cdll.LoadLibrary(lib_path[0])

    return self._dlltype(name)
  File "//anaconda/envs/wen2/lib/python2.7/ctypes/__init__.py", line 365, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: dlopen(//anaconda/envs/wen2/lib/python2.7/site-packages/libxgboostwrapper.so, 6): Library not loaded: @rpath/./libgomp.1.dylib
  Referenced from: //anaconda/envs/wen2/lib/python2.7/site-packages/libxgboostwrapper.so
  Reason: image not found

我不知道下一步该做什么.

I have no idea what to do next.

推荐答案

你下载的包镜像损坏.你应该怎么做:

The package image you download is corrupt. What you should do :

首先使用(在终端中)删除您的 xgboost 包:

First remove your xgboost package with (in the terminal) :

conda 移除 xgboost

conda remove xgboost

然后在 https://anaconda.org/aterrel/xgboost 使用其他软件包重新安装所以就写吧:

Then reinstall with an other package at https://anaconda.org/aterrel/xgboost So just write :

conda 安装 py-xgboost

conda install py-xgboost

然后就可以在python控制台查看安装了:

Then you can check the installation in the python console :

导入 xgboost

应该没问题.
