我在Windows 7上安装了Anaconda python,然后使用这里的说明手动安装了xgboost包:How to install xgboost package in python (windows platform)?(它没有安装在anaconda下,但是在一个单独的目录中)
我将以下内容放在test.py中:
import sys
sys.path.append('C:<path>/xgboost/python-package')
import xgboost
当从命令行(例如,来自cygwin)导入时,导入正常。 但是,如果我使用Spyder IDE或Anaconda附带的IPython,我会得到
WindowsError Traceback (most recent call last) <ipython-input-14-afdaff4619ce> in <module>()

我检查过sys.executable,我在shell和IPython中运行相同的python。打印sys.path显示在两种情况下正确的位置都是路径的一部分。知道发生了什么吗?我真的很想能够使用IDE。
