AutoModel vs PreTrainedModel difference/relationship
The AutoModel description is:“This is a generic model class that will be instantiated as one of the base model classes of the library when created with thefrom_pretrained()class method or thefrom_config()class method.”The PreTrainedModel description is:“Base class for all models.”Does that mean that AutoModel is a type/subclass of PreTrainedModel? What is the relationship/difference between those two classes exactly?
