Hi.

I want to know is there any efficient way to get some rows from a given tensor, like lookup_embedding in tensorflow.

For a given tensor with `requires_grad = True`

, it will applied some functions/changes/masks, and then used as a look up table. Thus I am trying to find exactly the same way what `tf.nn.embedding_lookup`

does.

Directly `tensor[index]`

works, I wonder, is there more efficient way to do that.

Appreciate for any replies.
