V. Troubleshooting

1. Printing During Initialization

Problem Description:

The first startup and loading after installation will be relatively slow

Solution:

During initialization, all components need to be loaded and cached for the first time; normal use is possible afterward

2. Graphics Card Driver

Problem Description:

The software can start without connecting the sensor, but fails to start when the sensor is connected, and the command line shows similar error reports or outputs as follows

Command Line Output
1段错误已中止(核心已转储)
2Segmentation Fault
3Init infer engine
4infer session using CPU(GPU)

Solution:

It is most likely a graphics card driver issue. First, install a compatible graphics card driver (if the graphics card is an NVIDIA card). Check if the following command outputs normally; if not, install a compatible graphics card driver first.

Command Line Input
nvidia-smi
