Reshape

## reshape(input, shape) -> Tensor

Returns a tensor with the same data and number of elements as `input`

,
but with the specified shape. When possible, the returned tensor will be a view
of `input`

. Otherwise, it will be a copy. Contiguous inputs and inputs
with compatible strides can be reshaped without copying, but you should not
depend on the copying vs. viewing behavior.

See `torch_Tensor.view`

on when it is possible to return a view.

A single dimension may be -1, in which case it's inferred from the remaining
dimensions and the number of elements in `input`

.

## Examples

```
if (torch_is_installed()) {
a <- torch_arange(0, 3)
torch_reshape(a, list(2, 2))
b <- torch_tensor(matrix(c(0, 1, 2, 3), ncol = 2, byrow=TRUE))
torch_reshape(b, list(-1))
}
