Why Is the GPU Display Abnormal?
Symptom
The following issues occur when nvidia-smi command is used to check the GPU usage.
- On the device with one GPU, the following information is displayed:
No devices were found
Solution
- Check whether the ECS, for example, of the PI2 or G6 flavor, is using NVIDIA Tesla T4 GPUs.
- If yes, rectify the fault by following the instructions provided in Why Is the T4 GPU Display Abnormal?
- If no, go to the next step.
- Check the system log /var/log/message for any reported driver-related errors.
- If the error message "Failed to copy vbios to system memory" is displayed, the possible causes may be frequent driver loading/unloading. You are advised to enable the driver's persistence mode to keep the driver in the loading state.

- If "Failed to copy vbios to system memory" is not displayed, go to the next step.
- If the error message "Failed to copy vbios to system memory" is displayed, the possible causes may be frequent driver loading/unloading. You are advised to enable the driver's persistence mode to keep the driver in the loading state.
- Check whether the ECS uses Tesla 510.xx.xx.
- If yes, the driver version may be incompatible with the image. You are advised to change the driver version. For details, see GPU Driver.
- If no, go to the next step.
- Restart the ECS and run the nvidia-smi command to check whether the usage of GPUs is normal.
