Error reporting using NVIDIA SMI:
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running
This is a common problem, which often occurs in Ubuntu systems. The main reason is that the system kernel has been upgraded, resulting in the mismatch between the new kernel and the original graphics card driver
Solution 1:
Just execute two commands:
Sudo apt get install DKMS
sudo DKMS install – M NVIDIA – V 440.44 (440.44 indicates the driver version number)
Use the command ll/usr/SRC/to view the nvidia-440.44/ folder below. The version number varies from computer to computer
Details of error reporting are as follows
root@OpenWrt :~# /root/connect_ net.sh
-ash: /root/connect_ net.sh: not found
When running a script, the above error occurs. The variables in the script are defined as
code = curl - O/dev/null - SW% {http_code} www.baidu. Com
After querying, it is found that the shell only supports ash in openwrt, while Bash is used by default in Linux and Ubuntu
The solution here is when defining variables, the left and right sides of the equal sign '=' are not left blank, as shown in the example
code = curl - O/dev/null - SW% {http_code} www.baidu. Com
The operation of variables in openwrt still needs attention

the error is due to the problem of parameter transmission. First, we need to check whether the parameter is correct
after checking, we find that the name is wrong, The case is not distinguished, so it can’t be found all the time. It’s successful to run after modification.
