Why do I need to do a transpose in Anchor 3D head

[chr10003566]

When I try to set the is_transpose false. the result is error.

I don't know, I guess it may be related to the size order of the anchor. When I change the anchor size to

sizes=[
                [2.5981, 0.8660,  1.],  # 1.5/sqrt(3)
                [1.7321, 0.5774,  1.],  # 1/sqrt(3)
                [1., 1., 1.],
                [0.4, 0.4, 1],
            ],

I am Still unable to obtain correct results.

你好， 请问你弄明白这个问题了吗？ 应该不只是anchor顺序的问题， 在进入bbox_head之前， 特征的形状是: [n, c, n_x, n_y]， 我觉得是因为作者觉得 n_x 对应W, n_y对应H？ 所以做了transpose.

我不理解的是， 从雷达坐标系上， x正方向是向前的， y正方向是向左的， n_x就正好对应H， n_y就正好对应W 为什么要改呢

Have you up the project ? can you provide me steps to build and run properly ?
