// This op was originally written by the Learn2Compress team.
// It takes in a list of indices, an encoding table which consists of
// integer indices into a codebook with floating point vectors.
// For each index, it looks up the corresponding row in the encoding table and
// for each entry in the row of the encoding table, it looks up the
// corresponding row in the codebook and populates it in an output embedding.
// The average of the output embeddings for each of the input indices is the
// output of this op.
