This fork of http://sourceforge.net/projects/pythonnet/ allows easy calling of python functions from C#.
- All calls to python should be inside a "using (Py.GIL()) {/* Your code here */}" block.
- Import python modules using dynamic mod = Py.Import("mod"), then you can call functions as normal, eg mod.func(args).
- Use mod.func(args, Py.kw("keywordargname", keywordargvalue)) to apply keyword arguments.
- All python objects should be declared as 'dynamic' type.
- Mathematical operations involving python and literal/managed types must have the python object first, eg np.pi2 works, 2np.pi doesn't
EG:
static void Main(string[] args) { using (Py.GIL()) { dynamic np = Py.Import("numpy"); dynamic sin = np.sin; Console.WriteLine(np.cos(np.pi*2)); Console.WriteLine(sin(5)); double c = np.cos(5) + sin(5); Console.WriteLine(c); dynamic a = np.array(new List<float> { 1, 2, 3 }); dynamic b = np.array(new List<float> { 6, 5, 4 }, Py.kw("dtype", np.int32)); Console.WriteLine(a.dtype); Console.WriteLine(b.dtype); Console.WriteLine(a * b); Console.ReadKey(); } }
outputs:
