This just needs to be double-checked and might already be integrated.
I have modified one line of the Challenge text and the code cell. For the second part (saving the measurements of PoseNet), I have added an extra tip to the Challenge text so that the students can use the GUI they developed in the previous part to make the measurements with PoseNet. I thought that these could be nice additions, but of course, fell free to leave them out or change them at will (I could also make changes if you have comments on the code/instructions).
