V. Troubleshooting

1. Printing During Initialization

Problem Description:

The first startup and loading after installation may be relatively slow.

Solution:

During initialization, all components need to be loaded and cached for the first time. Normal usage will be restored in subsequent starts.

2. Graphics Card Driver

Problem Description:

The software can start when no sensor is connected, but fails to start when the sensor is connected. The command line shows similar errors or outputs as follows:

Command Line Output
1Segmentation fault (core dumped)
2Segmentation Fault
3Init infer engine
4infer session using CPU(GPU)

Solution:

This issue is most likely caused by a graphics card driver problem. 1. First, install a compatible graphics card driver. 2. If the graphics card is an NVIDIA card, check whether the following command outputs normally. If not, install a compatible NVIDIA graphics card driver first.

Command Line Input
nvidia-smi

3. Error Handling
