> 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.
