Module 3: took long time to run preprocess function

[mingyu-yuan]

It took a long time to run the preprocess function both locally and on datahub. Could we export a pickle file of the preprocessed dataframe so folks can load it if the function turns out to take a long time to run?

Great suggestion Mingyu! I'm reviewing the lesson notebook again now. I also notice the lag, especially on DataHub.

Since I'll be covering that section next week anyway, I'll go ahead and export the pickle file to share via Slack the day of the lesson.

Awesome!
