Problems in the optional assignment of week 2 in the part about L1 and L2 norms

The part about L1 and L2 norms is returning the message “L1_test is not defined” and “L2_test” is not defined. The code can’t be changed. Does anybody could help me to find out what is happening? Thanks in advance!

That just means you haven’t run the previous cells in the notebook. Try “Cell → Run All Above” and then try your test cell again.

If you search the notebook, you’ll find that the public_tests are imported in the cell for basic_sigmoid, but just doing “Cell → Run All Above” should take care of that. Well, as long as none of the earlier cells before basic_sigmoid throw any errors.

Ok PaulinPaloAlto! It worked…Thank you very much!
