运行时到5000轮时下面这些代码触发except捕获异常，但捕获之后GPU和CPU利用率就为0了 class Compose(object): def init(self, transforms, ctx=None): self.transforms = transforms self.ctx = ctx

def __call__(self, data):
    ctx = self.ctx if self.ctx else {}
    for f in self.transforms:
        try:
            data = f(data, ctx)
        except Exception as e:
            stack_info = traceback.format_exc()
            logger.warn("fail to map op [{}] with error: {} and stack:\n{}".
                        format(f, e, str(stack_info)))
            raise e
    return data

然后找到具体触发的位置 im = self._mixup_img(sample['image'], sample['mixup']['image'], factor) gt_bbox1 = sample['gt_bbox'] gt_bbox2 = sample['mixup']['gt_bbox'] gt_bbox = np.concatenate((gt_bbox1, gt_bbox2), axis=0) gt_class1 = sample['gt_class'] gt_class2 = sample['mixup']['gt_class'] gt_class = np.concatenate((gt_class1, gt_class2), axis=0)

    gt_score1 = sample['gt_score']
    gt_score2 = sample['mixup']['gt_score']
    gt_score = np.concatenate(
        (gt_score1 * factor, gt_score2 * (1. - factor)), axis=0)

是concatenate出错，具体是什么原因报错的，是我的数据问题吗？
