Set element in an Tensor

[DimitriTimoz]

Maybe it's a dumb question and I just didn't well read the doc but Is it possible to assign a value at a position in a tensor?
Something like that:

        self.adjacency_matrix.set((x, y), 1);

I believe Tensors are immutable. You can build them up from vectors or iterators but I think it's difficult and maybe impossible to mutate specific elements.

@DimitriTimoz yes, tensors are immutable. The way to change the value of a specific element would be to use the Tensor::slice_assign method, which returns a new (copied) tensor. This requires a tensor to copy as the replacement tensor. If this code is in a hot loop and the device is a GPU, I would recommend that you avoid recreating this replacement tensor to avoid device<>host synchronization.
