The error is telling you that you have an out of date version of numpy. If you used pipto install things you can simply run pip install numpy -U, or download the appropriate version from their website.
该错误告诉您 numpy 的版本已过时。如果你曾经pip安装过东西，你可以简单地运行 pip install numpy -U，或者从他们的网站下载合适的版本。

In case
如果
pip install -U numpy
pip install -U numpy
doesn't work (even with sudo), you may want to make sure you're using the right version of numpy. I had the same "numpy.core.multiarray failed to import" issue, but it was because I had 1.6 installed for the version of Python I was using, even though I kept installing 1.8 and assumed it was installing in the right directory.
不起作用（即使使用 sudo），您可能需要确保使用正确版本的 numpy。我有同样的“numpy.core.multiarray 无法导入”的问题，但这是因为我为我使用的 Python 版本安装了 1.6，即使我一直安装 1.8 并假设它安装在正确的目录中。
I found the bad numpy version by using the following command in my Mac terminal:
我在 Mac 终端中使用以下命令发现了错误的 numpy 版本：
python -c "import numpy;print numpy.version;print numpy.file";
蟒蛇-c“进口numpy的;打印numpy的版本;打印numpy的文件”;
This command gave me the version and location of numpy that I was using (turned out it was 1.6.2). I went to this location and manually replaced it with the numpy folder for 1.8, which resolved my "numpy.core.multiarray failed to import" issue. Hopefully someone finds this useful!
这个命令给了我我正在使用的 numpy 的版本和位置（结果是 1.6.2）。我去了这个位置并手动将其替换为 1.8 的 numpy 文件夹，这解决了我的“numpy.core.multiarray 无法导入”问题。希望有人觉得这很有用！
