This package implements abstractions found in torch.cuda to facilitate writing device-agnostic code.

current_device	Returns current device for cpu.
current_stream	Returns the currently selected Stream for a given device.
is_available	Returns a bool indicating if CPU is currently available.
is_initialized	Returns True if the CPU is initialized.
synchronize	Waits for all kernels in all streams on the CPU device to complete.
stream	Wrapper around the Context-manager StreamContext that selects a given stream.
set_device	Sets the current device, in CPU we do nothing.
device_count	Returns number of CPU devices (not cores).
StreamContext	Context-manager that selects a given stream.
