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. - Then call
PythonEngine.Initialize()
. If you plan to use Python objects from multiple threads, also callPythonEngine.BeginAllowThreads()
. - 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:

Showing the top 5 NuGet packages that depend on pythonnet:
Package | Downloads |
---|---|
Python.Included
Python.Included is an automatic deployment mechanism for .NET packages which depend on the embedded Python distribution. This allows libraries depending on Python and/or Python packages to be deployed via Nuget without having to worry about any local Python installations. |
|
Numpy.Bare
C# bindings for NumPy on Win64 - a fundamental library for scientific computing, machine learning and AI. Does require Python 3.7 with NumPy 1.16 installed! |
|
Gradient.Runtime
Core runtime components for Gradient |
|
LostTech.NumPy
.NET bindings for NumPy. Requires the actual Python with NumPy installed. |
|
LostTech.TensorFlow
FULL TensorFlow 2.5+ for .NET with Keras. Build, train, checkpoint, execute models. Samples: https://github.com/losttech/Gradient-Samples, https://github.com/losttech/YOLOv4, https://github.com/losttech/Siren Deep learning with .NET blog: https://ml.blogs.losttech.software/ Comparison with TensorFlowSharp: https://github.com/losttech/Gradient/#why-not-tensorflowsharp Comparison with TensorFlow.NET: https://github.com/losttech/Gradient/#why-not-tensorflow-net Allows building arbitrary machine learning models, training them, and loading and executing pre-trained models using the most popular machine learning framework out there: TensorFlow. All from your favorite comfy .NET language. Supports both CPU and GPU training (the later requires CUDA or a special build of TensorFlow). Provides access to full tf.keras, estimators and many more APIs. Free for non-commercial use. For licensing options see https://losttech.software/buy_gradient.html !!NOTE!! This version requires Python 3.x x64 to be installed with TensorFlow 2.5.x. See the official installation instructions in https://www.tensorflow.org/install/ (ensure you are installing version 2.5 to avoid hard-to-debug issues). Please, report any issues to https://github.com/losttech/Gradient/issues For community support use https://stackoverflow.com/ with tags (must be all 3 together) tensorflow, gradient, and .net.
