Visual studio can't see Anaconda's modules
Resolved it myself
In the PATH variable
C:\ProgramData\Anaconda3
C:\ProgramData\Anaconda3\Library\mingw-w64\bin
C:\ProgramData\Anaconda3\Library\usr\bin
C:\ProgramData\Anaconda3\Library\bin
C:\ProgramData\Anaconda3\Scripts
should go first
I have 2 Python environments (Python 3.6 by Visual studio 2017 and Python 3.7 by Anaconda)
When I run a script I get an error that import numpy

Traceback (most recent call last):   File
  "C:\ProgramData\Anaconda3\lib\site-packages\numpy\core__init__.py",
  line 16, in 
      from . import multiarray ImportError: DLL load failed: The specified module could not be found.
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.
Original error was: DLL load failed: The specified module could not be
  found.

As a temporary fix I run Visual Studio from Anaconda prompt.
How can I fix the environment so that I could run Visual Studio as usually by double click? Do I need to change PATH somehow?
Right click-> Activate Environment didn't help either.
