title: Get a flat view of a list of torch tensors
body: <p>Given a list of tensors <code>lst</code>, how can I get a flattened view of all their elements? I can get a copy with <code>flat = torch.hstack([t.flatten() for t in lst])</code>, but I would like any changes done on the <code>flat</code> to be visible in their original list elements.</p>
