Jupyter notebook Kernal not connected

Hi I’m pretty new to Deep Learning …I’m trying to setup the AWS . I used the setup_t2.sh script and modified to t2.micro instead of t2.xlarge . After all my instance is created and ssh to aws console . Now i launched the jupyter notebook and the output is as follows

ubuntu@ip-10-0-0-9:~$ jupyter notebook

Now i’m trying to use the IP:8888 to see the Jupyter with password dl_course and try to create the new python condo_root under nbs. Up to this ok … When new file is created it says kernal is not connected … Please see the attached picture
But i could see the following output from my pc
