I am converting a jagged nested tensor to a padded tensor, then adding Rotary positional embeddings, then converting it back to a jagged tensor. The forward pass is just fine, but the backwards pass breaks. It is probably because the offsets object changes throughout the forward pass, but I...
Currently, I would have to do a workaround like this, where I am unsure if the backward pass is preserved correctly: cls_token=torch.randn(1,256)concatenated_tensors=[torch.cat((cls_token,t),dim=0)fortinout.unbind()]nested.as_nested_tensor(concatenated_tensors) Additional context torch==...

Neural networks (NNs) are a collection of nested functions that are executed on some input data. These functions are defined by parameters (consisting of weights and biases), which in PyTorch are stored in tensors. Training a NN happens in two steps: ...
