    The recipe argument is combined with our previous training command and COCO pre-trained weights to run the recipes over the model. For example, a command for pruning YOLACT would look like this:
 ```bash
 python train.py \
---recipe=../recipes/yolact.pruned.yaml \
+--recipe=../recipes/yolact.pruned.md \
 --resume=zoo:cv/segmentation/yolact-darknet53/pytorch/dbolya/coco/base-none \
