path is not defined in CPPRunCard when treatcards is called outside launch

[valassi]

Hi @oliviermattelaer this is one pending issue from #780. I take this and assign it to you. I have no idea how to solve it.

The problem is that reset_simd relies on self.path from CPPRunCard. This is correctly called in launch. But it is not if treatcards is called outside launch.

I added two debug lines

 class CPPRunCard(banner_mod.RunCardLO):
     def reset_simd(self, old_value, new_value, name):
+        print('DEBUG CPPRUNCARD', dir(self))
+        print('DEBUG CPPRUNCARD path', self.path)
         if not hasattr(self, 'path'):
             logger.warning('WARNING! CPPRunCard instance has no attribute path')
             return

From launch

./bin/mg5_aMC 

set stdout_level DEBUG
set zerowidth_tchannel F
generate g g > t t~
output madevent ../TMPOUT/CODEGEN_mad_gg_tt --hel_recycling=False --vector_size=16384 --me_exporter=standalone_cudacpp

I have pushed in the gpucpp branch a fix about this, I let you include it in this repo by updating the sub-repo

Thanks Olivier, I added this fix in PR #788, this can be closed
