For the times that you mention that you currently use Jupyter, how is it better than simply randomly selecting a small subset of data at the beginning and then writing your code in a full featured IDE with debugging functionality (including the ability to add breakpoints and see variable contents at those points, etc.)? The one line at the beginning to randomly subset the large data set is easy to delete or comment out once you have the code working the way you like - to me it seems more effective to do that in a native IDE like Eclipse+PyDev or in a lightweight IDE like Spyder than to use Jupyter, which requires so many compromises.
