安装了anaconda3，自带numpy库，但不能导入,问题出在哪里？

Question

是我在jupter notebook网页上输入import numpy后,显示ImportError,但我已经安装了numpy库。
以下是错误的信息：

ImportError Traceback (most recent call last)

During handling of the above exception, another exception occurred:

ImportError: 
Importing the multiarray numpy extension module failed. Most 
likely you are trying to import a failed build of numpy. 
If you're working with a numpy git repo, try git clean -xdf (removes all 
files not under version control). Otherwise reinstall numpy. 
Original error was: cannot import name 'multiarray' 

问题补充：1.我已经在网上搜索了的问题，有人说需要卸载numpy库后重新装，试了但不管用，同时，我又重装了anaconda，也不管用。

2.我的电脑上还同时安装了独立的python3,python2。python3是默认系统。

Answer 1

看情况是你安装的numpy有问题,是没法导入multiarray这个包

Answer 2

如果你是windows系统应该看看环境变量是不是设置到了anaconda的目录下
如果你是linux系统应该看看是不是设置了软链到anaconda的python

Answer 3

问题解决了吗？
