如何解决networkx stochastic_block_model 需要太多内存来构建
伙计们！我正在尝试从移动数据创建 SBM。我正在根据移动性数据计算 size_list 和概率矩阵，并尝试将其用作构建 SBM 的输入。
我当前的大小列表是 package filmoteca;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class GestionBDD {
private static String datosConexion = "jdbc:mysql://127.0.0.1:3306/";
private static String baseDatos = "cine";
private static String usuario = "root";
private static String pass = "";
private static String tabla = "pelicula";
private Connection con;
public GestionBDD() {
try {
con = DriverManager.getConnection(datosConexion,usuario,pass);
try{
crearBDD();
crearTablas();
}catch(Exception e){
e.printStackTrace();
}
}catch(SQLException e) {
e.printStackTrace();
}
}
public void crearBDD() throws Exception{
String query = "CREATE DATABASE IF NOT EXISTS"+ baseDatos +";";
Statement stat = null;
try{
stat = con.createStatement();
stat.executeUpdate(query);
con = DriverManager.getConnection(datosConexion+baseDatos,pass);
}catch(SQLException e){
e.printStackTrace();
}finally{
stat.close();
}
}
public void crearTablas() throws Exception{
String query = "USE DATABASE "+baseDatos+";"+
"CREATE TABLE IF NOT EXISTS"+" "+tabla+"("
+ "titulo VARCHAR(30),"
+ "director VARCHAR(30),"
+ "pais VARCHAR(30),"
+ "duracion FLOAT,"
+ "genero VARCHAR(30));";
Statement stat = null;
try{
stat = con.createStatement();
stat.executeUpdate(query);
con = DriverManager.getConnection(datosConexion+baseDatos,pass);
}catch(SQLException e){
e.printStackTrace();
}finally{
stat.close();
}
}
}
，只有 12 个“块”。
概率矩阵为：
[3583,2809,8,3250,1404,7382,18,4450,4,1247,22,6]

构建网络需要大量 RAM，即使最终图的大小并不大。我查看了文档和脚本，但不知道如何更改构建函数以不使用这么多 RAM。
有没有合适的方法来构建这样的图？
谢谢
