This API is mainly used in Graph Learning domain, which should be used in conjunction with `paddle.geometric.sample_neighbors` API. And the main purpose is to reindex the ids information of the input nodes, and return the corresponding graph edges after reindex. Take input nodes x = [0, 1, 2] as an example. If we have neighbors = [8, 9, 0, 4, 7, 6, 7], and count = [2, 3, 2], then we know that the neighbors of 0 is [8, 9], the neighbors of 1 is [0, 4, 7], and the neighbors of 2 is [6, 7]. Then after graph_reindex, we will have 3 different outputs: reindex_src: [3, 4, 0, 5, 6, 7, 6], reindex_dst: [0, 0, 1, 1, 1, 2, 2] and out_nodes: [0, 1, 2, 8, 9, 4, 7, 6]. We can see that the numbers in `reindex_src` and `reindex_dst` is the corresponding index of nodes in `out_nodes`. Note: The number in x should be unique, otherwise it would cause potential errors. We will reindex all the nodes from 0. Args: x (Tensor): The input nodes which we sample neighbors for. The available data type is int32, int64. neighbors (Tensor): The neighbors of the input nodes `x`. The data type should be the same with `x`. count (Tensor): The neighbor count of the input nodes `x`. And the data type should be int32. value_buffer (Tensor, optional): Value buffer for hashtable. The data type should be int32, and should be filled with -1. Only useful for gpu version. Default is None. index_buffer (Tensor, optional): Index buffer for hashtable. The data type should be int32, and should be filled with -1. Only useful for gpu version. `value_buffer` and `index_buffer` should be both not None if you want to speed up by using hashtable buffer. Default is None. name (str, optional): Name for the operation (optional, default is None). For more information, please refer to :ref:`api_guide_Name`. Returns: - reindex_src (Tensor), the source node index of graph edges after reindex. - reindex_dst (Tensor), the destination node index of graph edges after reindex. - out_nodes (Tensor), the index of unique input nodes and neighbors before reindex, where we put the input nodes `x` in the front, and put neighbor nodes in the back.

This API is mainly used in Graph Learning domain, which should be used in conjunction with `paddle.geometric.sample_neighbors` API. And the main purpose is to reindex the ids information of the input nodes, and return the corresponding graph edges after reindex. Take input nodes x = [0, 1, 2] as an example. For graph A, suppose we have neighbors = [8, 9, 0, 4, 7, 6, 7], and count = [2, 3, 2], then we know that the neighbors of 0 is [8, 9], the neighbors of 1 is [0, 4, 7], and the neighbors of 2 is [6, 7]. For graph B, suppose we have neighbors = [0, 2, 3, 5, 1], and count = [1, 3, 1], then we know that the neighbors of 0 is [0], the neighbors of 1 is [2, 3, 5], and the neighbors of 3 is [1]. We will get following outputs: reindex_src: [3, 4, 0, 5, 6, 7, 6, 0, 2, 8, 9, 1], reindex_dst: [0, 0, 1, 1, 1, 2, 2, 0, 1, 1, 1, 2] and out_nodes: [0, 1, 2, 8, 9, 4, 7, 6, 3, 5]. Note: The number in x should be unique, otherwise it would cause potential errors. We support multi-edge-types neighbors reindexing in reindex_heter_graph api. We will reindex all the nodes from 0. Args: x (Tensor): The input nodes which we sample neighbors for. The available data type is int32, int64. neighbors (list|tuple): The neighbors of the input nodes `x` from different graphs. The data type should be the same with `x`. count (list|tuple): The neighbor counts of the input nodes `x` from different graphs. And the data type should be int32. value_buffer (Tensor, optional): Value buffer for hashtable. The data type should be int32, and should be filled with -1. Only useful for gpu version. Default is None. index_buffer (Tensor, optional): Index buffer for hashtable. The data type should be int32, and should be filled with -1. Only useful for gpu version. `value_buffer` and `index_buffer` should be both not None if you want to speed up by using hashtable buffer. Default is None. name (str, optional): Name for the operation (optional, default is None). For more information, please refer to :ref:`api_guide_Name`.
