Want to create a Deep Learning framework from scratch?
Checkout this resource:

In this book, you will create a deep learning framework called "DeZero" from scratch (from zero), which is the original framework of this book. With minimal code, the framework's modern features are realized. In this book, you will make this small - yet powerful enough - framework in a total of 60 steps. It will deepen your knowledge of modern frameworks such as PyTorch and TensorFlow.
There's another github link (https://github.com/oreilly-japan/deep-learning-from-scratch-...) with the code for all 60 steps, but not the explanatory text.
