在 anaconda 中导入 xgboost？

Question

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost; make -j4

我使用官方文档在 ubuntu 上安装了 xgboost。没有错误，但是当我启动我的 ipython notebook 时，它是 anaconda 环境， import xgboost 显示错误，这不是模块。

如何在我的 anaconda python 环境中导入 xgboost？

是否需要修改ubuntu中的一些环境变量？

Answer 1

我在使用 Spyder 时也发生了同样的事情。我可以使用终端（带有弃用警告）导入它，即：

   pinaki@Excalibur:~$ python
   Python 3.6.1 |Anaconda custom (64-bit)| (default, May 11 2017, 13:09:58) 
   [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
   Type "help", "copyright", "credits" or "license" for more information.
   >>> from xgboost import XGBClassifier
   /home/pinaki/anaconda3/lib/python3.6/site-packages/sklearn/cross_validation.py:44: DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20.
    "This module will be removed in 0.20.", DeprecationWarning)
    >>>

但是在使用 Spyder 尝试运行相同代码时出现以下错误：

  from xgboost import XGBClassifier
  Traceback (most recent call last):

  File "<ipython-input-1-9b31cfdb821c>", line 1, in <module>
  from xgboost import XGBClassifier

  File "/media/pinaki/MyStuff/Work/Machine Learning A-Z Template Folder/Part 10 - Model Selection & Boosting/Section 49 - XGBoost/XGBoost/xgboost.py", line 30, in <module>
  from xgboost import XGBClassifier

  ImportError: cannot import name 'XGBClassifier'

并且 pip install xgboost 返回了以下输出：

   Requirement already satisfied: xgboost in /home/pinaki/xgboost/python-package
   Requirement already satisfied: numpy in /home/pinaki/anaconda3/lib/python3.6/site-packages (from xgboost)
   Requirement already satisfied: scipy in /home/pinaki/anaconda3/lib/python3.6/site-packages (from xgboost)

Answer 2

对我来说，通过将工作文件从 xgboost.py 重命名为其他名称，问题得到解决。

Answer 3

您必须转到 xgboost 文件夹和运行 setup.py 中的 python-package 文件夹。

之后

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost; make -j4

运行

cd python-package; sudo python setup.py install
