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, estimators and many more.
Free for non-commercial use. For licensing options see https://losttech.software/buy_gradient.html
This version requires Python 3.x x64 to be installed with tensorflow 1.15.x. See the official installation instructions in https://www.tensorflow.org/install/pip#older-versions-of-tensorflow (ensure you are installing version 1.15 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.

This version requires Python 3.x x64 to be installed with tensorflow or tensorflow-gpu. See the official installation instructions in https://www.tensorflow.org/install/pip#older-versions-of-tensorflow (ensure you are installing version 1.15 to avoid hard-to-debug issues).
If your app, that uses LostTech.TensorFlow, 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.
- enhanced Tensor<T>
- added licensing via Azure Subscription (must be admin of subscription): https://portal.azure.com/#create/losttechllc.tensorflow
- fixed off-by-one errors in passing `Index` and `Range` counting from the end
- support more NumPy functions
- added `PythonSlice`
- added .NET types for `ArithmeticError`, `FloatingPointError`, `OverflowError`, and `ZeroDivisionError`
- fixed a few GIL-related crashes
- replaced expiration with licenses
- improved typing on many APIs
- fixed inability to access static settings
- strongly-typed wrappers for Tensor
- enhanced ndarray<T>
- improved exception handling and debugging
- core runtime components include source and debug symbols
- LINQ enumerables and 1D .NET arrays are now automatically converted to Python lists for compatibility with bad TensorFlow APIs (can be disabled)
- TensorFlow 1.15
- strongly-typed accessors for ndarray<T>
- arithmetic, bitwise and comparison operators on Tensors (note, now to check for null `is null` must be used instead of `== null`)
- StartUsing extension on classes like Session, variable_scope, etc to allow simpler `using` blocks in .NET
