Hi @z52527 ，we can check the result in two ways, and you can select one after your evaluation:
- Generic method:
develop adef lookup_scores(indices, offsets)API forBatchedDynamicEmbeddingTables. It's process is close to forward() but don't need to do deduplication. Just lookup the scores usingfind_pointersas you already used.
But in the test script, you need to figure out how to get theBatchedDynamicEmbeddingTablesfromDistributedModelParallel.
So it may cost more.
2.Only checking the masking's result under debug mode in C++, so it will also make no effect to users.

rename to num_keys to avoid confusion with the size of embedding table.
