inference with Multiple GPU

[xiaoxifuhongse]

I got a server with two GPUs, both NVIDIA GeForce RTX 2080 SUPER , I want to run several lidars, so I want to make use of both ,
But when I cudaSetDevice(1), there is a bug like:

(pillars_infer:72328): GLib-GIO-CRITICAL **: 15:31:49.133: g_dbus_proxy_new: assertion 'G_IS_DBUS_CONNECTION (connection)' failed

so when the first gpu out of memory how can I choose the other?
