Dependencies

The project was run on a conda virtual environment on Ubuntu 18.04.5 LTS.

Checkout the requirements.txt file, if you have conda pre-installed cd into the directory where you have downloaded the source code and run the following

conda create -n contrastivemixup python==3.7
conda activate contrastivemixup

pip install -r requirements.txt

Running Experiments

To run experiments they are launched from the train.py file. For example, to run ContrastiveMixup on MNIST use the following command

python train.py -c ./configs/mnist/contrastivemixup.json --pretrain

The trainer, data loader, model, optimizer, settings are all specified in the ./configs/mnist/contrastivemixup.json file. The --pretrain options specifies whether to run the pretraining phase (i.e. training the encoder).
