For multi-card tasks, please use `FLAGS_selected_gpus` environment variable to set the visible GPU device.

If :code:`device_ids` is None, environment variable of
:code:`FLAGS_selected_gpus` would be checked first. For example, if

be [
fluid.CUDAPlace(0), fluid.CUDAPlace(1), fluid

If :code:`FLAGS_selected_gpus` is not set, all visible
