在Ubuntu18的开发板上安装1,4,0版本toolkit-lite,按照rk1808计算棒WIKI教程操作了,运行toolkit-lite的example报错如下:
--> Load RKNN model
done
--> Init runtime environment
E RKNNAPI: rknn_init, driver open fail! ret = -12(ERROR_NOT_SUPPORTED)!
E Catch exception when init runtime!
*************************
all device(s) with ntb mode:
TS018083200400969
*************************
E ['TS018083200400969']
E Traceback (most recent call last):
File "/home/firefly/archiconda3/envs/rknn/lib/python3.7/site-packages/rknnlite/api/rknn_lite.py", line 152, in init_runtime
self.rknn_runtime.build_graph(self.rknn_data, self.load_model_in_npu)
File "rknnlite/api/rknn_runtime.py", line 356, in rknnlite.api.rknn_runtime.RKNNRuntime.build_graph
Exception: RKNN init failed. error code: RKNN_ERR_DEVICE_UNAVAILABLE
Init runtime environment failed
在x86机子上相同操作就能正常调用npu。
请问问题怎么解决呢,
