Tensors
Tensors are the basic components in TensorFlow. A tensor is a multidimensional collection of data elements. It is generally identified by shape, type, and rank. Rank refers to the number of dimensions of a tensor, while shape refers to the size of each dimension. You may have seen several examples of tensors before, such as in a zero-dimensional collection (also known as a scalar), a one-dimensional collection (also known as a vector), and a two-dimensional collection (also known as a matrix).
A scalar value is a tensor of rank 0 and shape []. A vector, or a one-dimensional array, is a tensor of rank 1 and shape [number_of_columns] or [number_of_rows]. A matrix, or a two-dimensional array, is a tensor of rank 2 and shape [number_of_rows ...
