AutoModels¶
In many cases, the architecture you want to use can be guessed from the name or the path of the pretrained model you are supplying to the from_pretrained method.
AutoClasses are here to do this job for you so that you automatically retrieve the relevant model given the name/path to the pretrained weights/config/vocabulary:
Instantiating one of AutoModel, AutoConfig and AutoTokenizer will directly create a class of the relevant architecture (ex: model = AutoModel.from_pretrained('bert-base-cased') will create a instance of BertModel).
