The random seeds are clear during the initialization of HepRndmEngines

Dear Gaudi Developers,

I am Tao Lin from IHEP, Beijing.

I want to set the random seeds in Python script directly. Following is my code:

seed = [42]

rndmengine = HepRndm__Engine_CLHEP__RanluxEngine_("RndmGenSvc.Engine", Seeds=seed, OutputLevel=DEBUG) 
rndmengine.Seeds = seed
rndmengine.Luxury = 6
rndmengine.SetSingleton = True

But the problem is that seed in the output is always 1234567.

Then I find the seeds are always clear (https://gitlab.cern.ch/gaudi/Gaudi/-/blob/master/GaudiSvc/src/RndmGenSvc/HepRndmEngines.cpp#L69):

  // Initialize engine
  template <class TYPE>
  StatusCode Engine<TYPE>::initialize() {
    auto& seeds = m_seeds.value();
    seeds.clear();
    StatusCode status = RndmEngine::initialize();
    if ( m_seeds.size() == 0 ) {
      // Default seeds
      long theSeed = 1234567;
      seeds.push_back( theSeed );
      seeds.push_back( 0 );
    }

So my question is that is this a bug? If this is not a bug, what's the right way to set the random seeds?

Thank you very much!

Tao Lin
