## Training
|
|
|
|
**Start Training:** `python3 train.py` to begin training after downloading COCO data with `data/get_coco2017.sh`. Each epoch trains on 117,263 images from the train and validate COCO sets, and tests on 5000 images from the COCO validate set.
|
|
|
|
**Resume Training:** `python3 train.py --resume` to resume training from `weights/last.pt`.
|
|
|
|
**Plot Training:** `from utils import utils; utils.plot_results()`
|
|

|
|
|
|
### Image Augmentation
|
|
|
|
`datasets.py` applies OpenCV-powered (https://opencv.org/) augmentation to the input image. We use a **mosaic dataloader** to increase image variability during training.
