| the two different ways of constructing MaskedTensors: |
| masked_tensor(data, mask, requires_grad=True/False) -- NO differentiable constructor and always a leaf |
| as_masked_tensor(data, mask) -- differentiable constructor |
| |
| Like torch.tensor(data), masked_tensor(data, mask) will provide a UserWarning if data.requires_grad=True |
| as_masked_tensor does not take in requires_grad -- it just takes on the requires_grad from data |
| |
| Therefore, there are 6 cases to test and we use `mean` as a proxy to test the different combinations |
| |
| Assuming mt.mean().backward() is run after each constructor: |
| |
| Case 1a: |
| values.requires_grad = True |
| mt = masked_tensor(values, mask, requires_grad=True) |
| yields |
| - Provide a UserWarning because values.requires_grad=True |
| - values.grad = None |
| - mt.grad is a MaskedTensor with the correct gradient |
| |
| Case 1b: |
| values.requires_grad = False |
| mt = masked_tensor(values, mask, requires_grad=True) |
| yields |
| - values.grad = None |
| - mt.grad is a MaskedTensor with the correct gradient |
| |
| Case 2a/2b: |
| values.requires_grad = True/False |
| mt = masked_tensor(values, mask, requires_grad=False) |
| |
| will both yield a RuntimeError of "element 0 of tensors does not require grad and does not have a grad_fn" |
| as expected. When values.requires_grad=True, we will also get a UserWarning |
| |
| Case 3a: |
| values.requires_grad = True |
| mt = as_masked_tensor(values, mask) |
| yields |
| - values.grad is a MaskedTensor with the correct gradient |
| - mt.grad is None and gives a UserWarning that |
| "The .grad attribute of a Tensor that is not a leaf Tensor is being accessed. Its .grad" |
| |
| Case 3b: |
| values.requires_grad = False |
| mt = as_masked_tensor(values, mask) |
| |
| will yield a RuntimeError of "element 0 of tensors does not require grad and does not have a grad_fn" |
| as expected. |
