Hello, when importing the variables to build the PD Model, it returns me the following error pointing the problem to the line ·127 ‘mths_since_last_record:>86’]]”

KeyError: 'Passing list-likes to .loc or [] with any missing labels is no longer supported, see https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#deprecate-loc-reindex-listlike'

HI Edu,
Did you use the code provided in the lecture? 
If you made some changes, could you please share them with us?
Best,

I had the same problem, even when I copied and pasted the lecture code.
It turns out that using .loc[ ] with one or more missing labels is now deprecated (starting in version 0.2.1.0).  The documentation (https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#indexing-deprecate-loc-reindex-listlike) suggests using .reindex() instead.
This worked for me:
inputs_train_with_ref_cat = loan_data_inputs_train.reindex([ list of column names ], axis=1)

Hello all,
I replaced .loc with .reindex and I get after
inputs_train = inputs_train_with_ref_cat.drop(ref_categories, axis = 1)
inputs_train.head()
Many NaN:

grade:A                              0
grade:B                              0
grade:C                              0
grade:D                              0
grade:E                              0
... mths_since_last_record:3-20 373028 mths_since_last_record:21-31 373028 mths_since_last_record:32-80 373028 mths_since_last_record:81-86 373028 mths_since_last_record:>=86 373028 Length: 104, dtype: int64

It seems, that it doesn't work really with .reindex.

If I open the data loan_data_inputs_train.csv and all other, I do not find any NaN. All data are normal.

Any idea?
