How epochs does it need to get a fair result?

[lucasjinreal]

I have trained about 50 epochs with batch size of 8 on kitti , and the loss is 15.0 approximate but still a little high.

model restored from ./model/model-50.
Epoch 1 : Loss:0.0: 100%|###############################################################################| 1978/1978 [05:00<00:00,  3.67it/s]
Epoch: 1  done. Loss: 15.919499275778374
Epoch Time Cost: 300.38 s
Epoch 2 : Loss:0.0: 100%|###############################################################################| 1978/1978 [04:59<00:00,  6.76it/s]
Epoch: 2  done. Loss: 15.914487312247466
Epoch Time Cost: 299.55 s
Epoch 3 : Loss:0.0: 100%|###############################################################################| 1978/1978 [05:02<00:00,  7.03it/s]
Epoch: 3  done. Loss: 15.917136192803918
Epoch Time Cost: 302.93 s
Epoch 4 : Loss:0.0: 100%|###############################################################################| 1978/1978 [04:56<00:00,  6.75it/s]
Epoch: 4  done. Loss: 15.917050718417423

Seems the loss is very hard to converge
