Description

make a not with a python  and a md paragragh, 

after the note process we restart the interpreter with a sh paragragh.

 

we run the note looply by api with a sleep time like this:

// code placeholder

while(1):
    cmd = "curl -X POST http://192.168.56.200:8080/api/notebook/job/2F3BU3GSB"
    rs = os.system(cmd)
    print(cmd)
    print("===========================")
    print(rs)

    time.sleep(10)

 

 

it works well at begining, but after 6 hours loop the interpreter not worked with nullpoint error

the screen shot and log is in the attach file
