> On flow initialization, Python processors requiring download of dependencies are temporarily marked "INVALID" by the framework, in order to resolve the dependencies.  Invocation of a "ProcessGroup / Start" action during this period of time excludes the affected Python processors, due to operant filter [1].
> Removal of the "IsValid" filter will cause these processors to be marked appropriately, which will cause them to be started once the dependencies are resolved.
