Significance is further explained in Yannic Kilcher's video. This seems trivial given the otherwise clear tutorial, but I cannot figure out how to adjust the sequence-to-sequence modeling code (at Sequence-to-Sequence Modeling with nn.Transformer and TorchText — PyTorch Tutorials 1.7.1 documentation) to perform sequence classification instead, and to do just that for not text but multi-feature sequences. distilling from Resnet50 (or any teacher) to a vision transformer. Model classes in 🤗 Transformers that don’t begin with TF are PyTorch Modules, meaning that you can use them just as you would any model in PyTorch for both inference and optimization..

For classification tasks, we must prepend the special [CLS] token to the beginning of every sentence. Sequence classification is the task of classifying sequences according to a given number of classes. Coming from computer vision and new to transformers? We will be using pretrained transformers rather than fine-tuning our own, so a low setup cost is needed. A base Transformer class that inherits from PyTorch’s nn.module is defined. Doing away with clunky for-loops, the transformer instead finds a way to allow whole sentences to simultaneously enter the network in batches.
