python - 在 32 位 msys 失败的 python 下安装 xgboost

Question

尝试安装 xgboost 失败..？Windows 和企业版版本为 Anaconda 2.1.0(64 位)。我该如何进行？我一直在使用 R，似乎很容易从 RStudio 在 R 中安装新包，但在 spyder 中并非如此，因为我需要转到命令窗口来执行此操作，然后在这种情况下它会失败。

import sys

print (sys.version)

Answer 1

我回答有点晚了，但我仍然会继续为仍然对安装有问题的任何人回答。我按照中列出的步骤 https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13043/run-xgboost-from-windows-and-python他们是这些步骤的简明版本，位于 https://github.com/dmlc/xgboost/tree/master/windows .我将在下面总结我所做的。

1) 下载 Visual Basic Studio。您可以在 visual studio 网站下载社区版。右上角有个“免费visual studio按钮”

2) 从xgboost/tree/master/windows 的git hub 存储库中复制所有内容，并在Visual studio 上打开Visual studio 现有项目

3) 您需要选择几个下拉菜单(“Release”和“X64”，然后从上方菜单中选择 build --> build all。它看起来应该类似于所附的屏幕截图。

4) 如果您看到消息 ========== Build: 3 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========, 它是一切顺利

5) 浏览到 XGB 安装文件所在的 python-packages 文件夹，然后运行安装命令“python setup.py install”。

希望这对您有所帮助。
