Config parameters for custom models
Hi everyone,I’ve faced a problem regarding the configuration parameters of a custom model (say distilbert). To elaborate, let’s give an example:Suppose we want to perform the text classification task. For this purpose, we have 2 approaches:we can directly useDistilBertForSequenceClassificationin hugging face modules (and just change the number of output in classifier):model = DistilBertForSequenceClassification.from_pretrained('distilbert-base-uncased')write a custom model and define a specific classification head:In the first approach,model.configgives the configuration of the model, but in the second, it rises an error:'Distilbert' object has no attribute 'config'.The question is, why does this happen?!Thanks
