Requirements

• Python >= 3.6
• PyTorch (GPU version) >= 1.5
• NumPy >= 1.13.3
• Scikit-learn >= 0.20

Getting started

• Change directory to ./filelists/cifar
• Download CIFAR-FS
• run python make.py in the terminal

Running the scripts

To train and test the PCL model in the terminal, use:

$ python run_PCL.py --dataset cifar --algorithm PCL_matchingnet --tao 2.0 --noise_type feature --noise_rate 0.2 --train_n_way 5 --test_n_way 5 --n_shot 5 --model_name Conv4 --device cuda:0
