Hello all~

For the F.conv1d function. Suppose I have the input

```
input = [[a, b, c],
[d, e, f]]
```

And I have the weight

```
weight = [[x, y],
[z, w]]
```

Mathematically, the F.conv1d function will return

```
output = [[a, b, c] * [x, y]] + [[d, e, f] * [z, w]] # * is the cross-correlation operator
```

Now my problem is, I want to obtain the result before the sum operation, that is

```
desired_output = [[[a, b, c] * [x, y]],
[[d, e, f] * [z, w]]]
```

How should I do so? The simplest solution is I can create multiple weights and then conv1d each of them with the corresponding input channel but that will involve a loop that I really donâ€™t want.

Best regards,
