bug1------[TypeError("'numpy.int64' object is not iterable")
上面的代码我打印出来seg_res内容如下：
看着是没问题的，但是我用postman调试之后发现http服务返回错误，错误提示如下：

[TypeError("'numpy.int64' object is not iterable")，最终发现是因为python3中没有int64类型，只有int类型，而上面截图中?{'id': 0, 'type': 21中的0和21都是int64类型的，解决方法就是把这两个转换成int类型，然后错误解决。

这是因为测试时的postman发送的时候选择了text格式,没有选择json格式.
