Although the accepted answer is working, it's an unnecessary monkey-patch to a battle-tested library.

To fix the issue at it's core: Simply add (x86 or x64 - depending on your target) Microsoft Manifest Tool (mt.exe) to your path and install numpy through pip.

Since Visual Studio 2017, mt.exe has moved to the Windows SDK 7.1/8.1/10, which needs to be installed.

My mt.exe (x86) is located in: C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x86 so that's what I have added to the path, do that ether through Control Panel > System > Advanced system settings > Environment Variables or by using the pathman command in the console (cmd.exe).

Hope it helps, happy compiling!
