Bug/Feature Request Title
When I try to create depth 3 seed feature it always returns a column equal to 0 instead of expected values.
Bug/Feature Request Description
I built an example dataset described like this:
1
2
3
4
5
6
7
8
9
10
11
| python
Entityset: None
Entities:
pers [Rows: 1, Columns: 4]
cli [Rows: 29, Columns: 5]
k [Rows: 43, Columns: 4]
fin_exp [Rows: 43, Columns: 4]
Relationships:
cli.hid -> pers.hid
k.id_k -> cli.id_k
fin_exp.id_fin -> k.id_fin |
When I try to calculate a seed feature of depth 3 like
1
2
3
| python
ft.Feature(ft.Feature(ft.Feature(tset[&＃039;fin_exp&＃039;][&＃039;premium&＃039;], parent_entity &＃061; tset[&＃039;k&＃039;], primitive &＃061; Sum()), parent_entity &＃061; tset[&＃039;cli&＃039;], primitive &＃061; Sum()), parent_entity &＃061; tset[&＃039;pers&＃039;], primitive &＃061; Sum())
ft.Feature(ft.Feature(ft.Feature(tset[&＃039;fin_exp&＃039;][&＃039;id_fin&＃039;], parent_entity &＃061; tset[&＃039;k&＃039;], primitive &＃061; NumUnique()), parent_entity &＃061; tset[&＃039;cli&＃039;], primitive &＃061; Sum()), parent_entity &＃061; tset[&＃039;pers&＃039;], primitive &＃061; Sum()) |
it returns a column (one value in this case) fulls of zeroes instead of actual values. For comparison if I count on a duplicate
1
| tset[&＃039;k&＃039;][&＃039;idf&＃039;] |
of index
1
| tset[&＃039;k&＃039;][&＃039;id_fin&＃039;] |
for the parent entity
1
2
| python
ft.Feature(ft.Feature(tset[&＃039;k&＃039;][&＃039;idf&＃039;], parent_entity &＃061; tset[&＃039;cli&＃039;], primitive &＃061; NumUnique()), parent_entity &＃061; tset[&＃039;pers&＃039;], primitive &＃061; Sum()) |
I get 43 - as expected since fin_exp and k have one-to-one relationship in the example.
Expected Output
1
2
3
| python
ft.Feature(ft.Feature(ft.Feature(tset[&＃039;fin_exp&＃039;][&＃039;id_fin&＃039;], parent_entity &＃061; tset[&＃039;k&＃039;], primitive &＃061; NumUnique()), parent_entity &＃061; tset[&＃039;cli&＃039;], primitive &＃061; Sum()), parent_entity &＃061; tset[&＃039;pers&＃039;], primitive &＃061; Sum())
ft.Feature(ft.Feature(tset[&＃039;k&＃039;][&＃039;idf&＃039;], parent_entity &＃061; tset[&＃039;cli&＃039;], primitive &＃061; NumUnique()), parent_entity &＃061; tset[&＃039;pers&＃039;], primitive &＃061; Sum()) |
should return the same value.
Output of

featuretools.show_info() still doesn't print any input. Branch is slightly behind master.
