Weights become NaN values after first batch step

WebUp until now, we’ve mostly been using pretrained models and fine-tuning them for new use cases by reusing the weights from pretraining. As we saw in Chapter 1, this is commonly referred to as transfer learning, and it’s a very successful strategy for applying Transformer models to most real-world use cases where labeled data is sparse.In this chapter, we’ll … WebGenerate data batch and iterator¶. torch.utils.data.DataLoader is recommended for PyTorch users (a tutorial is here).It works with a map-style dataset that implements the getitem() and len() protocols, and represents a map from indices/keys to data samples.
