Small typo fixes for into_to_cnns.ipynb
Small typo fixes for into_to_cnns.ipynb

Here's the page in question: https://www.tensorflow.org/beta/tutorials/images/intro_to_cnns

I fixed a small typo under the "Create a convolutional base" heading. Additionally, I removed "As you can see" from the final paragraph, given that the same phrase was used at the start of the previous paragraph. As you're reading through the page it can seem a bit clumsy.
