Tutorial - Migrating from pure PyTorch | fastai
https://docs.fast.ai/migrating_pytorch29.11.2021 · As you can see, migrating from pure PyTorch allows you to remove a lot of code, and doesn't require you to change any of your existing data pipelines, optimizers, loss functions, models, etc. Once you've made this change, you can then benefit from fastai's rich set of callbacks, transforms, visualizations, and so forth.
