At the end of Chapter2.1 - Hello Dask ipynb I am getting the following error:

In [6]:

columns_to_drop = missing_count_pct[missing_count_pct > 60].index
df_dropped = df.drop(columns_to_drop, axis=1).persist()
NameError Traceback (most recent call last)
<ipython-input-6-f9c9aebbd813> in <module>()
----> 1 columns_to_drop = missing_count_pct[missing_count_pct > 60].index
2 df_dropped = df.drop(columns_to_drop, axis=1).persist()

NameError: name 'missing_count_pct' is not defined

What is the reason?

Hey! Try and run the cells above the one you're running. That should fix it. The error you've submitted means you haven't made the variable yet.

Thank you for recommendation and my apologies: I did not wait for completion of evaluation of previous cell. It works fine now.

Thanks for the help, Shuyib. I've gone back and double checked the code anyways just to make sure there weren't any typos.
