Use register_for_auto_class() if you want the code files to be copied. If you instead prefer to use code on the Hub from another repo, 
you don't need to call it. In cases where there's more than one auto class, you can modify the config.json directly using the 
following structure:
json
"auto_map": {     
    "AutoConfig": "<your-repo-name>--<config-name>",     
    "AutoModel": "<your-repo-name>--<config-name>",
    "AutoModelFor<Task>": "<your-repo-name>--<config-name>",    
},
