<br />

UNSUPPORTED: No embedding lookup accelerator available on the tpu.
V1: Embedding lookup accelerator V1. The embedding lookup operation can only
be placed at the beginning of computation. Only one instance of
embedding
lookup layer is allowed.
V2: Embedding lookup accelerator V2. The embedding lookup operation can be
placed anywhere of the computation. Multiple instances of embedding
lookup layer is allowed.
