The implementation is as follows: 1. Check whether the length-based LoD, i.e., :code:`recursive_seq_lens` is valid. 2. Convert :code:`recursive_seq_lens` to a offset-based LoD. 3. Based on :code:`place` , copy the :code:`data` from a numpy array, list or existing DenseTensor to CPU or GPU device. 4. Set offset-based LoD to the output DenseTensor. Suppose we want to create a DenseTensor to hold data for word sequences, where each word is represented by an integer. If we want to create a DenseTensor to represent two sentences, one of 2 words, and one of 3 words. Then :code:`data` would be a numpy array of integers with shape (5, 1). :code:`recursive_seq_lens` would be [[2, 3]], indicating the word number in each sentence. This length-based :code:`recursive_seq_lens` [[2, 3]] would be converted to offset-based LoD [[0, 2, 5]] inside the function call. Args: data (numpy.ndarray|list|DenseTensor): a numpy array, a list or ad DenseTensor holding the data to be copied. recursive_seq_lens (list[list[int]]): a list of lists indicating the length-based LoD info. place (CPUPlace|CUDAPlace): CPU or GPU place indicating where the data in the created DenseTensor will be stored. Returns: A DenseTensor with tensor data and recursive_seq_lens info.
