Indent update

* Update general.py

refactor duplicate code

* 200 dpi

* Update train.py with simplified ckpt names

* Return default hyps to hyp.scratch.yaml

Leave line commented for future use once mystery of best finetuning hyps to apply becomes clearer.

* Force test_batch*_pred.jpg replot on final epoch

This will allow you to see predictions final testing run after training completes in runs/exp0

* Class frequency not calculated on resuming training

Calculation of class frequency is not needed when resuming training.
Anchors can still be recalculated whether resuming or not.

* Check rank for autoanchor

* Update train.py

no autoanchor checks on resume
