TensorFlow is an end-to-end open source platform for machine learning. This repository is a fork of tensorflow that leverages DirectML to provide cross-vendor hardware acceleration on Windows 10 and the Windows Subsystem for Linux (WSL). TensorFlow with DirectML enables training and inference of complex machine learning models on a wide range of DirectX 12-compatible hardware.

Getting Started

TensorFlow with DirectML is supported on both the latest versions of Windows 10 and the Windows Subsystem for Linux. For detailed instructions on getting started, see GPU accelerated ML training (

TensorFlow with DirectML is compatible with TensorFlow 1.15 and is supported for production use. Official Python packages are available on the tensorflow-directml PyPI project, and C library packages are available for download on GitHub.

The DirectML repository includes a few samples that have been tested to work with the latest builds on PyPI. These samples include both inference and training scripts, and you can either train the models from scratch or use the supplied pre-trained weights. However, we encourage testing on any TensorFlow 1.15-compatible models -- if you run into issues, please let us know!

System Requirements

Windows 10

  • Windows 10 Version 1709, 64-bit (Build 16299 or higher)
  • Python x86-64 3.5, 3.6, or 3.71
  • One of the following supported GPUs:
    • AMD Radeon R5/R7/R9 2xx series or newer
    • Intel HD Graphics 5xx or newer
    • NVIDIA GeForce GTX 9xx series GPU or newer

1 Note: Python 3.8 or newer is not currently supported. To use the official PyPi packages, the CPython interpreter is required. NumPy 1.19.4 is requires the KB4598291 to properly work on Windows.

Windows Subsystem for Linux

  • Windows 10 Insider Preview, 64-bit (Build 20150 or higher)
  • Python x86-64 3.5, 3.6, or 3.72
  • One of the following supported GPUs:

2 Note: Python 3.8 or newer is not currently supported. To use the official PyPi packages, the CPython interpreter is required.
