ResNet training in PaddlePaddle

This simple demo showcases ResNet50 training on ImageNet.

Run it with the commands below:

python -m paddle.distributed.launch --selected_gpus 0,1,2,3,4,5,6,7 -b 128 -j 4 [imagenet-folder with train and val folders]


To train the model, run docs/examples/paddle/resnet50/ with the desired ResNet depth and the path to the ImageNet dataset:

python -m paddle.distributed.launch --selected_gpus 0,1,2,3,4,5,6,7 -d 50 [imagenet-folder with train and val folders]

The training schedule in He et al. 2015 was used where learning rate starts at 0.1 and decays by a factor of 10 every 30 epochs.


usage: [-h] [-d N] [-j N] [-b N] [--lr LR] [--momentum M]
                [--weight-decay W] [--print-freq N]
