Anaconda Python - how to reinstall NumPy
提问by Azzam Alsharafi
I am using Anaconda 5.3.0's Python interpreter in Visual Studio Code. When I try to import sklearnI get an error:
我在 Visual Studio Code 中使用 Anaconda 5.3.0 的 Python 解释器。当我尝试导入时sklearn出现错误：
Traceback (most recent call last):

raise ImportError(msg)
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: DLL load failed: The specified module could not be found.
It looks like that I need to "reinstall" NumPy. I searched on the web, but I didn't find a way to "reinstall". There is only how to "install", and when I use
看起来我需要“重新安装”NumPy。我在网上搜索，但我没有找到“重新安装”的方法。只有如何“安装”，当我使用
conda install numpy
in Anaconda Prompt I get:
在 Anaconda Prompt 我得到：
Solving environment: done
# All requested packages already installed.
And if I tried to remove NumPy to install it again, it will remove everything, not just NumPy. So do I really need to "reinstall" NumPy to be able to import sklearn?
And if I do, how do I "reinstall" NumPy?
如果我尝试删除 NumPy 以重新安装它，它将删除所有内容，而不仅仅是 NumPy。那么我真的需要“重新安装” NumPy 才能导入sklearn吗？如果我这样做了，我该如何“重新安装”NumPy？

How to reinstall a package depends on the conda version.
如何重新安装软件包取决于 conda 版本。
newer versions(>= 4.6):
较新的版本(>= 4.6)：
conda install numpy --force-reinstall
older versions (< 4.6):
旧版本（< 4.6）：
conda install numpy --force

You will most likely have to uninstall NumPy and reinstall it.
您很可能必须卸载 NumPy 并重新安装它。
conda remove numpy
And then install it again:
然后再次安装：
conda install -c anaconda numpy

go to your project setting and change the interrupter(i had the same problem and it solved like this)
转到您的项目设置并更改中断器（我遇到了同样的问题，它是这样解决的）
