An op that receives embedding activations on the TPU.

    num_outputs, config, name=None

The TPU system performs the embedding lookups and aggregations specified by the arguments to TPUEmbeddingEnqueue(Integer/Sparse/SparseTensor)Batch. The results of these aggregations are visible to the Tensorflow Graph as the outputs of a RecvTPUEmbeddingActivations op. This op returns a list containing one Tensor of activations per table specified in the model. There can be at most one RecvTPUEmbeddingActivations op in the TPU graph.


  • num_outputs: An int that is >= 1. The number of output activation tensors, equal to the number of embedding tables in the model.
  • config: A string. Serialized TPUEmbeddingConfiguration proto.
  • name: A name for the operation (optional).


A list of num_outputs Tensor objects with type float32.
