the lab is stuck on the first section. I have tried all thing- restarting kernel, reboot, getting latest version. I am frustrated for past 9 hrs now and need immediate attention.  
I have run the cell shown in below image and it shows busy(\* sign). I reached out to coursera support and they said they cant help. PLEASE LOOK ASAP.
