I noticed after using APEX for a while that its execution plan only reports metrics for a third of the remote workers. This isn’t documented and it has consequences in terms of interpreting some of the metrics reported. For example, the number of episode per iteration is wrong while the number of steps sampled and trained are ok, all custom metrics are computed on this subset of workers, etc.
Is there a particular reason for reporting only 1/3 of the workers? Should this remain the default behavior or at least be configurable?
