Demo is not executing successfully

[shifaezainab]

The demo file is not running successfully at all. It's not showing any error and logs. I tried to decipher the code and found that in main.py file its not able to import "net_utils.utils" module. The code is stuck on line 22. I tried to print a string before the import and after the import. But only a string before the import statement is printed. For reference screenshot is attached.
. I have followed every step mentioned in Readme.md file. Please help.
