When distributed training is performed in the lab environment, you need to configure the networking information file for the current multi-card environment. If HUAWEI CLOUD is used, skip this section.
The Ascend 910 AI processor and 1980 AIServer are used as an example. The JSON configuration file of a two-card environment is as follows. In this example, the configuration file is named rank_table.json.

The following parameters need to be modified based on the actual training environment:
1.`server_num` indicates the number of hosts, and `server_id` indicates the IP address of the local host.
2.`device_num`, `para_plane_nic_num`, and `instance_count` indicate the number of cards.
3.`rank_id` indicates the logical sequence number of a card, which starts from 0 fixedly. `device_id` indicates the physical sequence number of a card, that is, the actual sequence number of the host where the card is located.
4.`device_ip` indicates the IP address of the NIC. You can run the `cat /etc/hccn.conf` command on the current host to obtain the IP address of the NIC.
5.`para_plane_nic_name` indicates the name of the corresponding NIC.
1.`board_id` indicates the environment in which the program runs.
2.`server_num` indicates the number of hosts, and `server_id` indicates the IP address of the local host.
3.`device_num`, `para_plane_nic_num`, and `instance_count` indicate the number of cards.
4.`rank_id` indicates the logical sequence number of a card, which starts from 0 fixedly. `device_id` indicates the physical sequence number of a card, that is, the actual sequence number of the host where the card is located.
5.`device_ip` indicates the IP address of the NIC. You can run the `cat /etc/hccn.conf` command on the current host to obtain the IP address of the NIC.
6.`para_plane_nic_name` indicates the name of the corresponding NIC.
After the networking information file is ready, add the file path to the environment variable `MINDSPORE_HCCL_CONFIG_PATH`. In addition, the `device_id` information needs to be transferred to the script. In this example, the information is transferred by configuring the environment variable DEVICE_ID.
