Training sample is showing NaN’s thus below statement is failing to execute with an exception that code contains NaNs.
df, y, nas, mapper = proc_df(joined, ‘Sales’, do_scale=True)
Has anyone faced similar issue?
Note: I’ve not made any changes to lesson 3 notebook yet I face this issue. I even tried restarting Kernel and executing all code lines again to see I could avoid NaN but it didn’t work.
