The framework is implemented and tested with Ubuntu 16.04, CUDA 8.0/9.0, Python 3, Pytorch 0.4/1.0/1.1, NVIDIA TITANX GPU.

• Cuda & Cudnn & Python & Pytorch

  This project is tested with CUDA 8.0/9.0, Python 3, Pytorch 0.4/1.0, NVIDIA TITANX GPUs.

  Please install proper CUDA and CUDNN version, and then install Anaconda3 and Pytorch. Almost all the packages we use are covered by Anaconda.

Download and unzip the datasets: MiniImageNet, TieredImageNet, DomainNet.

Here we provide the datasets of target domain in Google Drive, miniImageNet, tieredImageNet.

Format: (E.g. mini-imagenet)

MINI_DIR/
  --  train/
      --  n01532829/
      --  n01558993/
      ...
  --  train_new_domain/
  --  val/
  --  val_new_domain/
  --  test/
  --  test_new_domain/

First set the dataset path MINI_DIR/, TIERED_DIR/, DOMAIN_DIR/ for the three datasets.

For each dataset, we use its training set to train a pre-trained model (e.g. tiered-imagenet).

cd pretrain/
python -u main_resnet.py --epochs 50 --batch_size 1024  --dir_path TIERED_DIR 2>&1 | tee log.txt &

We then use the corresponding pre-trained model to train on each dataset. (e.g. mini-imagenet)

python -u train_cross.py --gpu_id 0 --net ResNet50 --dset mini-imagenet --s_dset_path MINI_DIR --fsl_test_path MINI_DIR --shot 5 --train-way 16 --pretrained 'mini_checkpoint.pth.tar' --output_dir mini_way_16

python -u test.py --load MODEL_PATH --root MINI_DIR
