PPYOLOE seg可训,其余暂不可训。暂未支持Fastdeploy。
我尝试了PPYOLOE-seg(640640)训练自己的数据集,检测效果良好,但分割掩膜有明显的锯齿,尤其是小目标,且评估segm, mAP异常。
同样的数据集使用MaskRCNN(8001280)检测分割效果要好的多,且segm mAP正常。
以下为PPYOLOE-seg验证Log:

看预测的结果也挺正常,得分都挺高。
另外我发现训练PaddleYOLO中这几个实例分割,显存占用异常大,PPYOLOE-seg-s 640输入尺寸,2 batchsize就要占12G显存。其他YOLOv5、6、8 seg 12G显存只能跑1个batchsize。我在使用YOLOv5-seg\YOLOv8-seg官方代码训练时,可以使用更大的batchsize和更大的输入尺寸(1280),也不会爆显存,且检测和分割效果要好很多。

显存问题确实存在,后续有空会继续排查,谢谢
