Fast Differential Privacy (fastDP) is a library that allows differentially private optimization of PyTorch models, with a few additional lines of code. The goal of this library is to make DP deep learning as similar to the standard non-private learning as possible, in terms of speed, memory cost, scalability, accuracy and hyperparameter-tuning. It supports all PyTorch optimizers, popular models in TIMM, torchvision, HuggingFace (up to supported modules), multiple privacy accountants, multiple clipping functions/styles, most parameter-efficient training methods, and distribute solutions such as DeepSpeed and FSDP. The library has provably little overhead in terms of training time and memory cost, compared with the standard non-private optimization.
