   i've managed to add the function calls for adapter control, compiled as explained here https://rusin.work/vjing/tools/spout-for-python, but still didn't make it work end-to-end with multiGPU setup. the lib and Spout don't issue errors anymore, but the final receiver doesn't show anything either.
   here is what i did:

   Spout.cpp:

   #define BOOST_PYTHON_STATIC_LIB
   #include "Spout.h"
   #include <boost/python.hpp>
   
   BOOST_PYTHON_MODULE(SpoutSDK)
   {
   	using namespace boost::python;
   
   	class_<SpoutSender>("SpoutSender")
   		.def("CreateSender", &SpoutSender::CreateSender)
   		.def("GetNumAdapters", &SpoutSender::GetNumAdapters)
   		.def("SetAdapter", &SpoutSender::SetAdapter)
   		.def("GetAdapter", &SpoutSender::GetAdapter)
   		.def("SayHello", &SpoutSender::SayHello)
   		.def("SendTexture", &SpoutSender::SendTexture)
   		.def("ReleaseSender", &SpoutSender::ReleaseSender)
   		;
   	class_<SpoutReceiver>("SpoutReceiver")
   		.def("pyCreateReceiver", &SpoutReceiver::pyCreateReceiver)
   		.def("GetNumAdapters", &SpoutReceiver::GetNumAdapters)
   		.def("SetAdapter", &SpoutReceiver::SetAdapter)
   		.def("GetAdapter", &SpoutReceiver::GetAdapter)
   		.def("pyReceiveTexture", &SpoutReceiver::pyReceiveTexture)
   		.def("ReleaseReceiver", &SpoutReceiver::ReleaseReceiver)
   		.def("SelectSenderPanel", &SpoutReceiver::SelectSenderPanel)
   		.def("GetWidth", &SpoutReceiver::GetWidth)
   		.def("GetHeight", &SpoutReceiver::GetHeight)
   		;
   }
   

   python calls (same for SpoutReceiver):

   adapter_num = 1
   spout_name = 'source'
   width = height = 512
   spoutSender = SpoutSDK.SpoutSender()
   spoutSender.SetAdapter(adapter_num)
   print(' .. Sender on GPU', spoutSender.GetAdapter(), 'of', spoutSender.GetNumAdapters())
   spoutSender.CreateSender(spout_name, width, height, 0) 
   print(' .. Sender created')
   

   further advices are welcome

   here are the compiled libs for all python 3.x versions
