Hi, Thank you for providing the quality code. I have a implementation detail question.

Why don't you just call optimizer.step() after meta_objective.backward()?

garage/src/garage/torch/algos/maml.py

Lines 124 to 127 in f056fb8

    
           self._meta_optimizer.zero_grad() 
        
           meta_objective.backward() 
        
           self._meta_optimize(all_samples, all_params)
