Python3，不能导入numpy

Question

I am unable to import numpy. Tried to uninstall and reinstall numpy by using pip and pip3. Checked PATH. I am using Python3 on Windows 10.

Below is the whole error:

Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

During handling of the above exception, another exception occurred:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. Here is how to proceed: - If you're working with a numpy git repository, try git clean -xdf (removes all files not under version control) and rebuild numpy. - If you are simply trying to use the numpy version that you have installed: your installation is broken - please reinstall numpy. - If you have already reinstalled and that did not fix the problem, then: 1. Check that you are using the Python you expect (you're using C:\\Python37\\python.exe), and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy versions you're trying to use. 2. If (1) looks fine, you can open a new issue at https://github.com/numpy/numpy/issues . Please include details on: - how you installed Python - how you installed numpy - your operating system - whether or not you have multiple versions of Python installed - if you built from source, your compiler versions and ideally a build log

 Note: this error has many possible causes, so please don't comment on
 an existing issue about this - open a new one instead.

Original error was: DLL load failed: The specified module could not be found.

如果您想在 Windows 上获得更无缝的体验，请尝试使用 PyCharm 或 Anaconda，它们会自动为您安装 numpy/scipy，而不是标准的 Python 解释器。
