Enable TensorFlow with DirectML on Windows
This release provides students, beginners, and professionals a way to run machine learning (ML) training on their existing hardware by using the TensorFlow with DirectML package for TensorFlow 1.15. To use DirectML on TensorFlow 2, check out the TensorFlow-DirectML-Plugin. Once set up, you can use your exisiting model scripts or check out a few samples on the DirectML repo.
Check your version of Windows
The TensorFlow with DirectML package on native Windows works starting with Windows 10, version 1709 (Build 16299 or higher). You can check your build version number by running
winver via the Run command (Windows logo key + R).
Check for GPU driver updates
Ensure that you have the latest GPU driver installed. Select Check for updates in the Windows Update section of the Settings app.
Set up TensorFlow with DirectML
We recommend setting up a virtual Python environment inside Windows. There are many tools that you can use to set up a virtual Python environment—for these instructions, we'll use Anaconda's Miniconda. The rest of this setup assumes that you use a Miniconda environment.
Set up Python environment
Download and install the Miniconda Windows installer on your system. There is additional guidance for setup on Anaconda's site. Once Miniconda is installed, create an environment using Python named directml, and activate it through the following commands.
In the commands below, we use Python 3.6. However, the tensorflow-directml package works in a Python 3.5, 3.6, or 3.7 environment.
conda create --name directml python=3.6 conda activate directml
Install the TensorFlow with DirectML package
Install the TensorFlow with DirectML package through pip by running the following command.
The tensorflow-directml package supports only TensorFlow 1.15.
pip install tensorflow-directml
Once you've installed the tensorflow-directml package, you can verify that it runs correctly by adding two tensors. Copy the following lines into an interactive Python session.
import tensorflow.compat.v1 as tf tf.enable_eager_execution(tf.ConfigProto(log_device_placement=True)) print(tf.add([1.0, 2.0], [3.0, 4.0]))
You should see output similar to the following, with the add operator placed on the DML device.
