Fix typo in comment

I came here through a websearch and am looking for code to select labels in images.
I'll work along the lines of what you wrote here, thanks!

Thanks for your PR! 👍 Hopefully the code helps to solve your problem

In the end I found a much easier way to do what I wanted (a way without labeling), but your code put me on the right track to find this way :)
