Error in Week 3 C1_W3_Logistic_Regression

Course Q&A Machine Learning Specialization Supervised ML: Regression and Classification

In the final C1_W3_Logistic_Regression code exercise, all code looks OK (All Tests Passed!)

However I get an indentation issue. All code has been triple check and indentation looks ok, error is:

Cell #UNQ_C3. Can’t compile the student’s code. Error: IndentationError(‘unindent does not match any outer indentation level’, (‘/tmp/student_solution_cells/cell_13.py’, 38, 22, ’ for i in range(m):\n’))

Sounds like in the 13th code cell in the notebook, you have some whitespace hiding where it shouldn’t be. Maybe you have a space and a tab adjacent each other.

Looks like the “for i in range(m)” statement there starts with a space. That’s maybe it.

Thanks for your kind reply. I’ve removed all whitespace thoroughly (4 spaces) and I still get the same issue. Can you help?

Check whether you renamed the notebook file.

You can’t rename a notebook and then submit it. The grader always uses the original notebook name, regardless of what notebook you have open when you click the “Submit” button.

Also, did you ever download the notebook to your local computer, edit it there, and then upload it back to Coursera Labs?

No I didn’t. But thanks anyway.

That worked! Thanks so much, such a dumb mistake, have been pulling my hair out… thank you!!!
