# Description

In the Camera class, we assumed that the default device for the torch
tensor is CPU when we allocate the `rot` buffer during init. This isn't
always the case if the user overwrites the torch device beforehand. This
fix explicitly sets the tensor device to CPU on allocation.

Fixes #1863
