FULL TensorFlow 1.10 for .NET with Keras. Build, train, checkpoint, execute models.

Comparison with TensorFlowSharp:
Comparison with 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 and tf.contrib APIs, including estimators.

This preview will expire.


This version requires Python 3.x x64 to be installed with tensorflow or tensorflow-gpu. See the official installation instructions in (ensure you are installing version 1.10 to avoid hard-to-debug issues).

Please, report any issues to

This version requires Python 3.x x64 to be installed with tensorflow or tensorflow-gpu. See the official installation instructions in (ensure you are installing version 1.10 to avoid hard-to-debug issues).

If your app, that uses Gradient, targets net4xx (like net472), you need to specify a proper runtime identifier to run and publish. e.g. "dotnet publish -r win" and "dotnet run -r win7-x64". Note, "run" requires specific identifier.

What's new

Preview 6:
- feature: enabled inheriting from TensorFlow classes. Now it is possible to build custom Keras layers, callbacks, etc
- feature: automatic marshalling of Gradient types for use with TensorFlow
- fixed an ability to modify collections belonging to TensorFlow objects
- fixed crash when enumerating TensorFlow collections without an explicit lock
- preview 6 will expire in March 2020

Preview 5.1:
- improved passing dictionaries
- setup: optionally specify Conda environment via an environment variable
- setup: fixed Conda environment autodectection on Linux
- improved argument types in many places
- Gradient warnings are now printed to Console.Error by default, instead of Console.Out
- fixed crashes on dynamic interop and multithreaded enumeration
- fixed some properties not being exposed
- preview 5.1 will expire in Oct 2019

Preview 5:
- support for indexing Tensor objects via `dynamic`
- allow using specific Python environment via GradientSetup.UsePythonEnvironment

Preview 4:
- support for Ubuntu 18.04 x64 and MacOS with .NET Core; other *nix OS might work too

Preview 2:
- dynamically typed overloads, that enable fallback for tricky signatures
- a common interface for tf.Variable and tf.Tensor
- enabled enumeration over TensorFlow collection types
