- `from openvino.runtime import Core`: This line imports the `Core` class from the `openvino.runtime` module. The `Core` class is the main entry point for using the OpenVINO™ toolkit in Python. It provides several methods to load and infer models, as well as to set and get configuration options.
- `Layout`: This is a class from the `openvino.runtime` module that represents a tensor layout. A tensor layout defines how the elements of a tensor are ordered in memory. There are several predefined layouts, such as `NCHW` and `NHWC`, which are commonly used in deep learning.
- `get_batch`: This is a function from the `openvino.runtime` module that returns the batch size of a given tensor shape. The batch size is the size of the first dimension of the tensor, which represents the number of input samples in a batch. For example, if a tensor has shape `(32, 3, 224, 224)`, the batch size is 32. The `get_batch` function takes a tensor shape as input and returns the batch size as an integer.
