What is the difference between arguments `ports_num` and `ports_num_for_sparse `
Created by: helinwang
According to https://github.com/PaddlePaddle/Paddle/blob/6aed264f0a4f8e045e5fc44fd7144fc727098070/paddle/utils/Flags.cpp#L38
DEFINE_int32(ports_num, 1, "The ports number for parameter send," " increment based on default port number"); DEFINE_int32(ports_num_for_sparse, 0, "The ports number for parameter send," " increment based on default (port + ports_num)");
Feels like it's hard to understand the difference.
