- 如果没有特别标记,NPU 上的结果与使用 FP32 的 GPU 上的结果结果相同。
- (\*) 这些模型在 NPU 上的结果与 GPU 上的混合精度训练结果一致,但低于 FP32 的结果。这种情况主要与模型本身在混合精度训练中的特点有关,
用户可以自行调整超参数来获得更高精度。
- (\*\*) GPU 上 yolox-s 在混合精度下的精度为 40.1 低于readme中 40.5 的水平;默认情况下,yolox-s 启用 persister_woker,但这个参数
- (\*\*) GPU 上 yolox-s 在混合精度下的精度为 40.1 低于readme中 40.5 的水平;默认情况下,yolox-s 启用 `persister_woker=True`,但这个参数
目前在NPU上存在一些bug,会导致在最后几个epoch由于资源耗尽报错退出,对整体精度影响有限可以忽略。
