Environment

Pythonnet version: 2.3
Python version: 3.5.5
Operating System: Windows 10

Details

hi,my code is:
static void Main(string[] args)
{
using (Py.GIL())
{
dynamic np = Py.Import("numpy");
Console.WriteLine(np.cos(np.pi * 2));

    dynamic sin = np.sin;
    Console.WriteLine(sin(5));

    double c = np.cos(5) + sin(5);
    Console.WriteLine(c);

    dynamic a = np.array(new List<float> { 1, 2, 3 });
    Console.WriteLine(a.dtype);

    dynamic b = np.array(new List<float> { 6, 5, 4 });
    Console.WriteLine(b.dtype);

    Console.WriteLine(a * b);
    Console.ReadKey();
}

}

my output is:

You can grab the wheels from appveyor artifacts for master branch.

Your "error CS1617" is due to some mismatch between build tools. Try updating vswhere.exe to latest version:
