Runner

Runner is an abstraction that takes all the logic of your deep learning experiment: the data you are using, the model you are training, the batch handling logic, and everything about the selected metrics and monitoring systems:

Runner

The Runner has the most crucial role in connecting all other abstractions and defining the whole experiment logic into one place. Most importantly, it does not force you to use Catalyst-only primitives. It gives you a flexible way to determine the level of high-level API you want to get from the framework.

For example, you could:

Finally, the Runner architecture does not depend on PyTorch in any case, providing directions for adoption for Tensorflow2 or JAX support. Supported Runners are listed under the Runner API section.
