Overview

A tensor is a multi-dimensional array used as the basic data structure. This array can have any number of dimensions, and is used to represent data of various types, such as numeric, boolean, or string values.

The dimensions of a tensor are often referred to as "ranks". For instance:

A rank 0 tensor is a scalar (a single number).
A rank 1 tensor is a vector (a 1D array).
A rank 2 tensor is a matrix (a 2D array).
A rank 3 tensor is a 3D array, and so on for higher dimensions.

Each tensor in TensorFlow is also associated with a data type (such as float32, int32, or string) and a shape. The shape of a tensor is the number of elements in each dimension.

For example, a 3x3 matrix has a shape of [3, 3].
