fastai is an open-source Python library that simplifies training fast and accurate neural nets. It is built on top of PyTorch and has become a popular tool for our data scientists. fastai simplifies painful aspects of model training such as preprocessing and loading data down to a few lines of code. It's built on deep learning best practices and has out-of-the-box support for computer vision, natural language processing (NLP) and more. The founders' motivation has been to create an easy-to-use library for deep learning and an improved successor to Keras. GCP, AWS and Azure all have already included fastai in their machine images. The creators of fastai, acknowledging the speed and safety limitations of Python, have announced embracing Swift as an alternative language for deep learning. We'll be closely watching this space.
