Setting trainer.devices does not propogate to datamodule.world_size

[dxoigmn]

For some reason, setting trainer.devices=2 does not also set datamodule.world_size to 2 even though this line exists:

MART/mart/configs/datamodule/default.yaml

Line 11 in eced15b

world_size: ${trainer.devices}

I think this is because many of the experiments modify datamodule.world_size:

MART/mart/configs/experiment/CIFAR10_CNN.yaml

Line 27 in eced15b

world_size: 1

MART/mart/configs/experiment/COCO_TorchvisionRetinaNet.yaml

Line 27 in eced15b

world_size: 1

MART/mart/configs/experiment/COCO_TorchvisionFasterRCNN.yaml

Line 28 in eced15b

world_size: 1

MART/mart/configs/experiment/ImageNet_Timm.yaml

Line 25 in eced15b

world_size: 1
