ray.tune.schedulers.HyperBandScheduler.debug_string

HyperBandScheduler.debug_string() → str

This provides a progress notification for the algorithm.

For each bracket, the algorithm will output a string as follows:

Bracket(Max Size (n)=5, Milestone (r)=33, completed=14.6%): {PENDING: 2, RUNNING: 3, TERMINATED: 2}

“Max Size” indicates the max number of pending/running experiments set according to the Hyperband algorithm.

“Milestone” indicates the iterations a trial will run for before the next halving will occur.

“Completed” indicates an approximate progress metric. Some brackets, like ones that are unfilled, will not reach 100%.
