When you call item(), the number is no longer a tensor, does this necessarily mean that it can no longer live on the gpu? The docs for .item() don’t say anything about the data moving, however, the docs for .tolist(), which is the same as .item() except for multiple items, says the data is moved to cpu first ‘if necessary’. What does that mean? https://pytorch.org/docs/stable/tensors.html#torch.Tensor.tolist 33
