将pandas字符串的数据帧转换为int的numpy数组(convert pandas dataframe of strings to numpy array of int)

 我的输入是一个带有字符串的pandas数据帧：  
>>> data
218.0                 
221.0                 
222.0                 
224.0    71,299,77,124
227.0     50,283,81,72
229.0              
231.0           84,349
233.0                 
235.0                 
240.0           53,254
Name: Q25, dtype: object
 
 现在我想要一个形状（.reshape（-1,2））numpy数组的int为每一行像这样：  
>>> data
218.0                      [] 
221.0                      []
222.0                      []
224.0    [[71,299], [77,124]]
227.0     [[50,283], [81,72]]
229.0                      []
231.0              [[84,349]]
233.0                      []
235.0                      []
240.0              [[53,254]]
Name: Q25, dtype: object
 
 我不知道如何通过矢量操作到达那里。 有人可以帮忙吗？ 

My input is a pandas dataframe with strings inside: 
>>> data
218.0                 
221.0                 
222.0                 
224.0    71,299,77,124
227.0     50,283,81,72
229.0              
231.0           84,349
233.0                 
235.0                 
240.0           53,254
Name: Q25, dtype: object
 
now i want a shaped ( .reshape(-1,2) ) numpy array of ints for every row like that: 
>>> data
218.0                      [] 
221.0                      []
222.0                      []
224.0    [[71,299], [77,124]]
227.0     [[50,283], [81,72]]
229.0                      []
231.0              [[84,349]]
233.0                      []
235.0                      []
240.0              [[53,254]]
Name: Q25, dtype: object

 做一些像：  
var script = {
    callAction: function () {

        $.ajax({
            url: 'Home/MapTest',
            type:'GET',
            data: JSON.stringify({ date: "your date" })
            dataType: "json",
            success: function (message) {
                var count = message.length;
                for (var i = 0; i < count; i++) {
                    $('#maplong').append(message[i].LATITUDE, "  ", message[i].LONGITUDE," ");
                }
            },
            complete: function () {
                alert('completed');
            }
        });
    }
}
 
 最好的祝福 

Just do something like: 
var script = {
    callAction: function () {

        $.ajax({
            url: 'Home/MapTest',
            type:'GET',
            data: JSON.stringify({ date: "your date" })
            dataType: "json",
            success: function (message) {
                var count = message.length;
                for (var i = 0; i < count; i++) {
                    $('#maplong').append(message[i].LATITUDE, "  ", message[i].LONGITUDE," ");
                }
            },
            complete: function () {
                alert('completed');
            }
        });
    }
}
