LoD is short for Level of Details and is usually used for varied sequence length. You can skip the following comment if you don't need optional LoD. For example, a LoDTensor X can look like the example below. It contains 2 sequences. The first has length 2 and the second has length 3, as described by x.lod. The first tensor dimension 5=2+3 is calculated from LoD if it's available. It means the total number of sequence element. In X, each element has 2 columns, hence [5, 2]. x.lod = [[2, 3]] x.data = [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]] x.shape = [5, 2] LoD can have multiple levels (for example, a paragraph can have multiple sentences and a sentence can have multiple words). In the following LodTensor Y, the lod_level is 2. It means there are 2 sequence, the first sequence length is 2 (has 2 sub-sequences), the second one's length is 1. The first sequence's 2 sub-sequences have length 2 and 2, respectively. And the second sequence's 1 sub-sequence has length 3. y.lod = [[2 1], [2 2 3]] y.shape = [2+2+3, ...] Examples: .. code-block:: python import paddle.fluid as fluid t = fluid.LoDTensor() Note: In above description, LoD is length-based. In Paddle internal implementation, lod is offset-based. Hence, internally, y.lod is represented as [[0, 2, 3], [0, 2, 4, 7]] (length-based equivlent would be [[2-0, 3-2], [2-0, 4-2, 7-4]]). Sometimes LoD is called recursive_sequence_length to be more self-explanatory. In this case, it must be length-based.
