Setting gpus with hydra
When setting a list of gpus with hydra, the list object is omegaconf.listconfig.ListConfig so it breaks the code here:

  
    
      pytorch-lightning/pytorch_lightning/trainer/distrib_parts.py
    
    
         Line 323
      in
      8211256
    
  
  
    

        
          
           if gpus is not None and (not isinstance(gpus, (int, str, list)) or isinstance(gpus, bool)): 
        
    
  


Should PL support setting gpus with ListConfig?
