Hi Luning, 

Thank you so much. That worked and the demo had run. However, it still gave 
me some errors for some reason. Also, the DEMO_OUTPUT folder that is 
created when the demo is run is empty and I could not find anything in it. 
I have attached the error and output files for your reference.


Thank you so much for your help,
