Python xgboost与anaconda的安装问题

我用的是蟒蛇。我首先切换到Python2（版本2.7.11）

我使用以下命令在anaconda中安装xgboost

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

然后我检查了xgboost是否已安装

conda list
xgboost                   0.3                      py27_0    akode

我在terminal中运行python，导入xgboost并得到以下错误

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()

    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)

我不知道下一步该怎么办。

你试过使用pip吗？

源代码激活您的环境

---

pip安装xgboost

首先需要通过“make”构建库，然后可以使用anaconda提示符进行安装

首先按照官方指南执行以下步骤（在Windows上的Git Bash中）：

最后，使用anaconda提示符执行以下操作：

cd xgboost\python-package  
python setup.py install 

也可以参考这些重要资源：

---

您下载的软件包映像已损坏。 你应该做什么：

首先移除xgboost软件包（在终端中）：

康达拆卸xgboost

然后在安装时使用其他软件包重新安装 所以只要写下：

康达安装py xgboost

然后，您可以在python控制台中检查安装：

导入xgboost

---

应该没问题。

我也有类似的问题

希望这能有所帮助

在我的ubuntu 14.04中，
第一：安装anaconda
第二：git克隆xgboost，制作并安装python包
第三：用蟒蛇设置xgboost。例如：
1） cdyourpath/xgboost/python包 2） 找到蟒蛇路径：

---

anaconda/bin/python setup.py安装
我也遇到了同样的错误。我完全卸载了pip unistall的xgboost。然后通过以下方式重新安装：

conda install -c bioconda xgboost=0.6a2

这似乎解决了问题

未加载库：@rpath//libgomp.1.dylib

这是关键

在我的例子中，它是“未加载库：/usr/local/opt/gcc/lib/gcc/6/libgomp.1.dylib”

我检查路径“/usr/local/opt/gcc/lib/gcc” 那里只有一个名为7的文件夹，没有6。
因此，我使用“sudo find/-name libgomp.1.dylib”查找我安装的所有gcc版本，我发现在另一个位置有一个版本6。
然后在“/usr/local/opt/gcc/lib/gcc”下创建一个名为6的文件夹，并将这些GCC6文件复制到其中。

---

最后，“导入xgboost”可以正常工作。

看起来这将安装过时的xgboost，以及sklearn版本0.16.1（过时）。这对我不起作用。我的python版本是3.5.2，我得到的错误是：

bash-4.3$python-V python 3.5.2:：Anaconda 4.2.0（x86_64）（/Users/xxx/Anaconda）bash-4.3$conda安装-c aterrel xgboost获取包元数据。。。。。。。。。解决包规格：。。。。不可满足错误：发现以下规范存在冲突：-python 3.5*-xgboost使用“conda info”查看每个包的依赖项

Ok您现在应该做的就是

conda安装py xgboost

，因为0.4.0是xgboost的旧版本谢谢，您的建议对我有用。您知道您的命令中的

bioconda

是什么意思吗？

cd xgboost\python-package  
python setup.py install
