rknn.bin.list_devices 没有列出设备

设备是3399proD


每次重启后正常，输入命令python3 -m rknn.bin.list_devices
可以列出设备：
*************************
all device(s) with ntb mode:
7d29104c41c174a5
*************************


过一段时间后，再输入命令python3 -m rknn.bin.list_devices
就变成：
*************************
None devices connected.
*************************

请问这是为何？

看你的描述可能是npu进入休眠了。
lsusb看下0x2207的设备还在不在

貌似设备是还在的,  ID 2207:0019 Fuzhou Rockchip Electronics Company

那你这情况下跑程序会出问题么？

会出现

过一两天我们会更新一版NPU驱动，到时候你再测试下。我们会内部先测试下这个问题

jefferyzhang，你这一两天我等的好辛苦,请快点发布
