netket.callbacks

Those callbacks can be used with the optimisation drivers.

For a detailed description of the run loop and all available callback hooks, see The Run Loop and Callback Hooks.

Abstract base class

AbstractCallback	Abstract base class for callbacks in advanced variational drivers.
StopRun	Exception to be raised by callbacks to gracefully stop the optimisation loop.
RunFinished	Exception to be raised by callbacks to end a run that has reached its end, for example the final time of a time evolution.

Built-in callbacks

EarlyStopping	A simple callback to stop NetKet if there are no more improvements in the training.
ConvergenceStopping	A simple callback to stop the optimisation when the monitored quantity gets below a certain threshold for at least patience steps.
InvalidLossStopping	A simple callback to stop the optimisation when the monitored quantity becomes invalid for at least patience steps.
Timeout	A simple callback to stop NetKet after some time has passed.
AutoChunkSize	Automatically tunes the chunk size for the (i) sampler, (ii) forward pass and (iii) backward pass of a driver and a variational state in order to avoid OOM errors.
AutoSlurmRequeue	A callback that automatically requeues a Slurm job if it is about to run out of time.
