When encountering the above problems, it may be the problem of GPU hardware. For example, Tesla T4 will encounter this problem, but use Tesla P4. Also, if you enable the mirror, remember to allocate memory parameters and use NVIDIA to run commands.

: cannot connect to X server

Generally, this problem is encountered when using a remote server, because the remote server cannot provide the service of the graphical user interface, and the X Server is a service program that provides graphic user interface on the Linux system.

We want to comment on the CV2.imshow function in the code. This function can directly transfer the window to display the picture under Windows. Using Linux in the command line cannot be displayed. Be careful not to use it like this.

and the CV.Waitkey function must be annotated.
