i’m getting this error I guess testing code is not written properly when u call a function what declared in the above cell is not getting initialised . I would like respected people to fix this bug . thank you

@javvadi111, please try again and double-check to make sure that you’ve run the cell with history = ... before you run the cell with utils.test_history(history)

@javvadi111 this is the way you can access your utils.py file. But I suspect the issue could be with the

URL of the white wine dataset

This could also happen if you have missed reading the below instruction give on the top of each grader cell with ##

Please uncomment all lines in this cell and replace those marked with # YOUR CODE HERE.
You can select all lines in this code cell with Ctrl+A (Windows/Linux) or Cmd+A (Mac), then press Ctrl+/ (Windows/Linux) or Cmd+/ (Mac) to uncomment.

Please share screenshot of submission grader output which will given us some insight on why it is failing.

DP

my problem was already solved
