Pytorch split tensor into batches
WebSplits a tensor into a specific number of chunks. the input tensor. Last chunk will be smaller if the tensor size along the given dimension dimis not divisible by chunks. Parameters input(Tensor) – the tensor to split chunks(int) – number of chunks to return dim(int) – dimension along which to split the tensor Next Previous WebOct 21, 2024 · If the total number of samples should be 2500, you should use this shape in dim0 via: XY = XY.view (-1, 2) # should have shape [2500, 2] now T = T.view (-1, 1) # should have shape [2500, 1] now Afterwards you can pass these tensors to a TensorDataset and this dataset to a DataLoader. Let me know, if you get stuck.

This is equivalent to calling torch.tensor_split (input, indices_or_sections, dim=0) (the split dimension is 0), except that if indices_or_sections is an integer it must evenly divide the split dimension or a runtime error will be thrown.
