from ignite.engine import Engine, Events from ignite.contrib.handlers import ProgressBar trainer = Engine(my_training_function) # Attach the ProgressBar handler to the trainer object ProgressBar(persist=False, bar_format=None).attach(trainer) # Begin training trainer.run(data_loader, max_epochs=n_epochs)
from ignite.engine import Engine, Events from ignite.contrib.handlers import ProgressBar evaluator = Engine(my_evaluation_function) # Attach the ProgressBar handler to the evaluator object ProgressBar(persist=False, bar_format=None).attach(evaluator) # Begin evaluation evaluator.run(data_loader)In this code example, the `ProgressBar` handler is attached to an Ignite evaluator object and used to display progress while evaluating a specified `data_loader`. Overall, the `ignite.contrib.handlers.ProgressBar` attachment provides a convenient way to add progress bars to Ignite training and evaluation loops for improved user experience. The package/library is `ignite`.
