解决方法：
打开上述anchor_target.py文件，然后修改下面几行为：
|
1 2 3 4 5 6 7 8 9 10 11 12 |
def anchor_inside_flags(flat_anchors, valid_flags, img_shape, allowed_border=0): img_h, img_w = img_shape[:2] if allowed_border >= 0: inside_flags = valid_flags & \ (flat_anchors[:, 0] >= -allowed_border).type(torch.uint8) & \ (flat_anchors[:, 1] >= -allowed_border).type(torch.uint8) & \ (flat_anchors[:, 2] < img_w + allowed_border).type(torch.uint8) & \ (flat_anchors[:, 3] < img_h + allowed_border).type(torch.uint8) else: inside_flags = valid_flags return inside_flags |

按照你这样改了，还是解决不了这个问题
每个人的情况不一样，这个可能不适合所有人。。。
好的，感谢您，这个问题解决了
没事~太客气啦
