Close large programs (important to read)

If we want to conduct other experiments, in order to avoid the occupation of critical resources between processes, we must stop the large program. The method is as follows: User name: pi

Password: yahboom

1. First of all, the interface of the big program must stay on this page. If not, please return to this page by yourself.

2. Then we enter the dog 's system and open the terminal.

3. Enter the following command to find out the process number of the large program

ps -ef | grep "python"

4. Then find the process number of mian.py. The process number is different each time you start the computer. You need to get it according to the actual situation. The tutorial here is 878.

5. Enter the following command to close the large program

xxxxxxxxxx
sudo kill 878  #878 is the process ID, which needs to be obtained based on actual conditions.

6. Make sure the big program is closed, and then check whether the big program is still running.

xxxxxxxxxx
ps -ef | grep "python"

Found that the big program has been closed.

If the main program is not closed, running a separate routine will cause the dog's screen to be distorted or black. The screen will not recover until the dog is restarted.
