AttributeError: module 'recordlinkage' has no attribute 'Index'

[boscoraju]

Hi @J535D165,

I am trying to run the example provided but I am running into an error about no attribute "index".

index = recordlinkage.Index(df_a, df_b)

---

index = recordlinkage.Index(df_a, df_b)
AttributeError: module 'recordlinkage' has no attribute 'Index'

Any help is much appreciated. Thank you.

Hello boscoraju,

I'm sorry for this stupid mistake. Use index = recordlinkage.Pairs(df_a, df_b) instead.

Index was used in an old version. It was confusing with the pandas.Index in the pandas API and therefore renamed.

For more docs: http://recordlinkage.readthedocs.io/en/latest/notebooks/link_two_dataframes.html

Good luck.

I've tried changing it to Pairs, but now have a problem with the index line from the example:

politie_sample = politie_sel.sample(frac = 0.001)
lbz_sample = lbz_sel.sample(frac = 0.001)

indexer = recordlinkage.Pairs(politie_sample, lbz_sample)
indexer.block('Gender')
candidate_links = indexer.index(politie_sample, lbz_sample)

Traceback (most recent call last):

. File "", line 6, in
candidate_links = indexer.index(politie_sample, lbz_sample)

File "C:\Anaconda3\lib\site-packages\recordlinkage\indexing.py", line 330, in index
d = next(self._iterindex(index_func, *args, **kwargs))

File "C:\Anaconda3\lib\site-packages\recordlinkage\indexing.py", line 483, in _iterindex
*args, **kwargs

TypeError: 'DataFrame' object is not callable

I've then tried to call the last line without data-frames as arguments, but then can't compute the length:

Traceback (most recent call last):

File "", line 1, in
len(candidate_links)

TypeError: object of type 'method' has no len()

When I then try to use the Compare function (it asks for an argument, so I supplied the indexer object), I get the following error message:

compare_cl = recordlinkage.Compare(indexer)
compare_cl.exact('Gender', 'Gender', label='Gender')
Traceback (most recent call last):

Is there a way to go back to the original Index function?
