questions about training time #6

Closed feixh closed 8 months ago

feixh commented 8 months ago

hi there,

In Figure 1 of your paper, you mentioned that training of DreamFusion takes more than 8 hours, and Magic3D takes more than 5 hours. But DreamFusion mentioned that their training time is about 1.5 hours, and Magic3D about 40 minutes. Why your reported training time of other approaches are much longer?

Thank you for your attention. When we mention GPU time in our paper, it is because DreamFusion and magic3D adopt multi-GPU training, so the GPU time is the time reported multiplied by the number of GPUs. For more details, you can refer to magic3D. 1111 2222
