As it seems torch.save() just saves to the disk, so it seems there is no need for (server) parent path, just the name of the file , in my case : ' http://my_model.pt ' .
Thanks for you help CostlyOstrich36

ClearML logs the paths as they are when torch.save() is run. Your problem currently is getting torch.save() to work, no?

The problem is with the path I am trying to save the model to.Therefore my question How do I extract paths inside ClearML?

yes of course I specified it with :
torch.save(state, f_path)
where f_path = os.path.join(tempfile.gettempdir(), 'trained_models') + '\ http://my_model.pt '

I think you need to specify some pythonic object to work with torch.save() - as it appears in their documentation:
