Why there are no logs and which model is saved?

I’m using Trainer to train my model.

I have the following outputs on screen:

Epoch Training Loss Validation Loss Accuracy
0 No log 1.114260 0.342667
1 No log 0.939480 0.545333
2 No log 0.816581 0.660000
3 No log 0.752204 0.710667
4 No log 0.741462 0.741333
5 No log 0.801005 0.754667
6 0.675800 0.892765 0.748000
7 0.675800 1.190328 0.752000
8 0.675800 1.272624 0.745333
  1. Why there are no logs for epochs 0-5 ? (Do I need to configure / enable them ?)
  2. Epoch #5 got best accuracy.
    When I will use predict, which model checkpoint will be used ? (the model which trained after 5 epochs or the model which trained after 8 epochs) ?
