Shapes, Dtypes & Indexing

Read a tensor's shape and slice into it.

Tensors Are Just Numbers in a Grid

A tensor is a box of numbers arranged in rows, columns, or deeper. Everything in deep learning flows through them.

Shape Describes the Layout

The shape tells you how many values sit along each dimension. Read it like dimensions of a box: rows by columns. 📦
