描述问题/Describe the bug

我们在阅读PP-YOLOE-s的配置时发现，这里：https://github.com/PaddlePaddle/PaddleDetection/blob/f06c929055c6979f8b1ca2bb3e97751f18fcfb2c/configs/ppyoloe/ppyoloe_crn_s_300e_coco.yml#L18 我们想请教一下，

  1. 这里的“batch_size: 32”是设置单张GPU上batch大小为32吗？

  2. 补充说明：好像这里的32跟PP-YOLOE论文中的描述并不是完全一致， 8ea5f6c34257172d64f4cb88168b2b2

目前ppdet配置中的batch size表示的是每张卡上的bs，我们在训练过程中为了最大限度利用gpu资源，s/m/l/x选择了不同的bs
