Dependencies

python 3.6.4
pytorch 0.3.1.post2
visdom

Usage

initialize visdom.

python -m visdom.server

train using CIFAR10 dataset. checkpoint will automatically be saved in checkpoint/run1 for every epoch.

python main.py --model_type skip_repeat --dataset cifar10 --env_name run1

you can load checkpoint and continue training. make sure --env_name matched to previous runs.

python main.py --model_type skip_repeat --dataset cifar10 --env_name run1 --load_ckpt True

you can check the training process.

you can also train using your own dataset. make sure your dataset is appropriate for pytorch ImageFolder class. please check data directory tree below.

python main.py --model_type skip_repeat --dataset custom_dataset --env_name run1
