Retrieve Momentum embedding parameters with debug support.
tf.raw_ops.RetrieveTPUEmbeddingMomentumParametersGradAccumDebug(
num_shards, shard_id, table_id=-1, table_name='', config='', name=None
)
An op that retrieves optimization parameters from embedding to host memory. Must be preceded by a ConfigureTPUEmbeddingHost op that sets up the correct embedding table configuration. For example, this op is used to retrieve updated parameters before saving a checkpoint.
