xgboost WinError127，windows 10，anaconda

Question

我试图在我的笔记本电脑上安装xgboost以用于anaconda。在关注此链接https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_For_Anaconda_on_Windows?lang=en之后，以及（我认为）每个步骤都正确实现后，当我尝试在anaconda中导入xgboost时，我得到：[WinError 127]找不到指定的过程。我已经搜索了很多，但仍然无法找到解决方案，所以我希望有人有光。感谢

编辑： 使用的代码就像在链接

中一样

import os

mingw_path = 'C:\\Program Files\\mingw-w64\\x86_64-5.3.0-posix-seh-rt_v4-rev0\\mingw64\\bin'

os.environ['PATH'] = mingw_path + ';' + os.environ['PATH']

import xgboost as xgb
import numpy as np

data = np.random.rand(5,10) # 5 entities, each contains 10 features
label = np.random.randint(2, size=5) # binary target
dtrain = xgb.DMatrix( data, label=label)

dtest = dtrain

param = {'bst:max_depth':2, 'bst:eta':1, 'silent':1, 'objective':'binary:logistic' }
param['nthread'] = 4
param['eval_metric'] = 'auc'

evallist  = [(dtest,'eval'), (dtrain,'train')]

num_round = 10
bst = xgb.train( param, dtrain, num_round, evallist )

bst.dump_model('dump.raw.txt')

错误：

Answer 1

如果你不想编译代码，你真的不必做所有这些。二进制文件（非正式地）可在因特网上获得。试试this。

编辑：

我只是重新阅读我的帖子。有可能你错过了VCOMP140.DLL。你的xgboost安装应该没问题（在帖子上有更多细节）。

您应该检查此路径：

mingw_path ='C：\ Program Files \ mingw-w64 \ x86_64-5.3.0-posix-seh-rt_v4-rev0 \ mingw64 \ bin'

这可能不正确
