Intel® Extension for TensorFlow*

Intel® Extension for TensorFlow* is a heterogeneous, high performance deep learning extension plugin based on TensorFlow PluggableDevice interface, aiming to bring Intel CPU or GPU devices into TensorFlow open source community for AI workload acceleration. It allows users to flexibly plug an XPU into TensorFlow on-demand, exposing the computing power inside Intel's hardware.

This diagram provides a summary of the TensorFlow* PyPI package ecosystem.

• TensorFlow PyPI packages: estimator, keras, tensorboard, tensorflow-base

• Intel® Extension for TensorFlow* package:

  intel_extension_for_tensorflow contains:

  • XPU specific implementation
    • Kernels & operators
    • Graph optimizer
    • Device runtime
