Returns loaded Delegate object.

<pre class="devsite-click-to-copy prettyprint lang-py tfo-signature-link"> <code>tf.lite.experimental.load_delegate( library, options=None ) </code></pre> <!-- Placeholder for "Used in" -->

Example usage:

import tensorflow as tf

try:
  delegate = tf.lite.experimental.load_delegate('delegate.so')
except ValueError:
  // Fallback to CPU

if delegate:
  interpreter = tf.lite.Interpreter(
      model_path='model.tflite',
      experimental_delegates=[delegate])
else:
  interpreter = tf.lite.Interpreter(model_path='model.tflite')

This is typically used to leverage EdgeTPU for running TensorFlow Lite models. For more information see: <a href="https://coral.ai/docs/edgetpu/tflite-python/">https://coral.ai/docs/edgetpu/tflite-python/</a>
