Hi, @sc0v0ne ,

Thank you for this!

Will review shortly and get back to you (sorry for late reply I was on holidays over December).

I finished the next module. I found another point that needs the same change. Just wanted to ask before you approve, wait until the weekend. Now I can push changes to the next module.

@mrdbourke Good morning, I fixed the other notebooks and the helper_functions.py file that had the function that was updated. I ran the notebooks to check for any errors, it went through all the cell steps and the result of the tensorboard that appears in the notebook on the board.

I'm a little late to the party, but I noticed you all aren't using a notebook review tool and wanted to invite you to review this pull request with GitNotebooks: https://gitnotebooks.com/mrdbourke/tensorflow-deep-learning/pull/611

It lets you do things like comment on rendered markdown and code cells, so might be an easy win for your PR reviews.
