Slice的结果现在会出现0Dim，导致SoloV2出错

solov2 受影响的代码
solov2_head.py

    def get_seg_single(self, cate_preds, seg_preds, kernel_preds, featmap_size,
                       im_shape, scale_factor):
        """
        The code of this function is based on:
            https://github.com/WXinlong/SOLO/blob/master/mmdet/models/anchor_heads/solov2_head.py#L385
        """
        h = paddle.cast(im_shape[0], 'int32')[0]
        w = paddle.cast(im_shape[1], 'int32')[0]

还有很多地方有影响
