pythonnet
is a package that gives .NET programmers ability to
integrate Python engine and use Python libraries.
Embedding Python in .NET
- You must set
Runtime.PythonDLL
property orPYTHONNET_PYDLL
environment variable, otherwise you will receiveBadPythonDllException
(internal, derived fromMissingMethodException
) upon callingInitialize
. Typical values arepython38.dll
(Windows),libpython3.8.dylib
(Mac),libpython3.8.so
(most other *nix). Full path may be required. - 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, egmod.func(args)
. You can also access Python objects viaPyObject
and dervied types instead of usingdynamic
. - Use
mod.func(args, Py.kw("keywordargname", keywordargvalue))
ormod.func(args, keywordargname: keywordargvalue)
to apply keyword arguments. - Mathematical operations involving python and literal/managed types
must have the python object first, eg.
np.pi * 2
works,2 * np.pi
doesn't.
Example
using var _ = Py.GIL();
dynamic np = Py.Import("numpy");
Console.WriteLine(np.cos(np.pi * 2));
dynamic sin = np.sin;
Console.WriteLine(sin(5));
double c = (double)(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 }, dtype: np.int32);
Console.WriteLine(b.dtype);
Console.WriteLine(a * b);
Console.ReadKey();
Output:
