有人可以解释这一行吗?我真的没有得到这个let部分.
我试着想一想,我不知道我是否做对了:我们绑定(nlt, nrt),结果split s lst; 而且split s lst本身就是(nlt, Root x nrt rst)
是吗?
这是完整的代码:
split :: Ord a => a -> Tree a -> (Tree a, Tree a)
split _ Empty = (Empty, Empty)
split s (Root x lst rst)

本文提到了4步交替训练,
根据我的收集,在阶段2 = RCNN中,RPN确实冻结了:
if self._is_training:
proposal_boxes = tf.stop_gradient(proposal_boxes)

因此,涵盖了培训RPN +冻结RPN层,然后进行RCNN培训,但是其他3个步骤又在哪里执行?
我想念什么吗?
我有一个叫做Task的课.头文件如下:
class Task
{
public:
Task();
//Methods Declarations
private:
int uid;
list<Task> l;
friend ostream & operator<<(ostream & os, const Task &t);
friend ostream & operator<<(ostream & os, const list<Task *> &l);
};

现在在我的主文件中,我运行:
Task * tasks[7];
for (int i = 0; i != 7; ++i)
tasks[i] = new Task();
delete [] *tasks;

在运行时,delete[] *tasks;我收到以下错误消息:
