Training is slow. about upsnet

K80 is ~2x slower than 1080 Ti (5.6 TFLOPS vs 11.3 TFLOPS). And we suggest use 8-16 GPUs for coco experiments. I think on COCO 10 days for 4 K80 GPU is a normal time. Please try smaller dataset such as Cityscapes.

Thank you. I'll try this.

@YuwenXiong Hi, What using 4 1080TI GPU on COCO? How long does it cost on COCO? I have tried to train cityscapes which cost me about 2 days.

4 1080Ti for cityscapes should be done < 1day, and for coco it will be ~7 days
