WebNov 2, 2024 · A tensor is an array that represents the types of data in the TensorFlow Python deep-learning library. A tensor, as compared to a one-dimensional vector or array or a two-dimensional matrix, can have n dimensions. The values in a tensor contain identical data types with a specified shape. Dimensionality is represented by the shape. WebCreates an iterator for elements of dataset. Pre-trained models and datasets built by Google and the community
