Week 3: about utils.py file

In the first lab of week 3, we defined a variable called
nn_models = utily.build_models()
when choosing the best model for neural networks. When I tried this on my notebook, it did not work because build_models was not defined. I tried to find the utils.py file online but I couldn’t find it. How can I access this file?

You have to download all the files, not only a notebook. Check this.


Thank you for your answer. This helped a lot
