Example Notebook:
-
The notebook was created on a Google Colab machine (GPU accelerated) which ran TensorFlow version 1.x
-
The notebook was tested with TensorFlow version 2.2.0 and Keras version 2.3.1 on a Google Colab machine (GPU accelerated) and worked when removing the parameter validate_indices from the call tf.nn.embedding_lookup (it is a deprecated argument).
-
If you have issues with eager execution with TensorFlow version 2.x or higher, issue #2 might help you.
