W2 A2 | Wrong values for grads['dw']

I think that means that either your notebook or your public_tests.py file are out of date. Please use the “get a clean copy” procedure documented on the FAQ Thread. Please read the instructions all the way to the end: you need to delete all the “dot py” files to make sure you get new versions of those as well. Then “copy/paste” your completed code back to the fresh copy of the notebook and let us know if that doesn’t help.
