Backend and Device

chainerx

ChainerX adds a level of abstraction between the higher level array operations and the lower level computations and resource management. This abstraction is managed by the ~chainerx.Backend and the ~chainerx.Device classes. Native (CPU) and CUDA backends are two concrete implementations currently provided by ChainerX but the abstraction allows you to plug any backend into the framework.
