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?

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:
https://pytorch.org/docs/stable/generated/torch.save.html

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