WebCallbacks API. A callback is an object that can perform actions at various stages of training (e.g. at the start or end of an epoch, before or after a single batch, etc). Write TensorBoard logs after every batch of training to monitor your metrics. Get a view on internal states and statistics of a model during training. WebThere are no special requirements for the last step in a pipeline, except that it has a fit function. All fit and fit_transform functions must take arguments X, y, even if y is not used. Similarly, for score to be usable, the last step of the pipeline needs to have a score function that accepts an optional y. Estimator types¶
