Pycharm导入numpy等报错
导入numpy，pycharm报错如下：
import numpy
Traceback (most recent call last):
File “D:\Program Files\Python36\lib\site-packages\numpy\core_init_.py”, line 16, in
from . import multiarray
ImportError: DLL load failed: 找不到指定的程序。
During handling of the above exception, another exception occurred:

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.
最后发现，之前自己用的是python2.7，更换为python3.7后，忘记更改系统变量。
将系统变量更成之后，将C:\Users\user\Anaconda3\Library\bin添加到系统变量，重启pycharm，运行成功。
