Hi Everyone
I tried to follow the same steps in Topic from Text on similar data as example. However, when I tri to fit the model with data I get this error.
IllegalArgumentException: requirement failed: Column features must be of type equal to one of the following types: [struct<type:tinyint,size:int,indices:array<int>,values:array<double>>, array<double>, array<float>] but was actually of type struct<type:tinyint,size:int,indices:array<int>,values:array<double>>.
My data:
Col => { "vec_json", "features" }

Row(vec_json='[{"type":0,"size":4927,"indices":[0,8,18,30,145,336,786,1231,1695,3653],"values":[2.0,1.0,1.0,2.0,1.0,2.0,1.0,1.0,2.0,1.0]}]', features=Row(type=0, size=4927, indices=[0, 8, 18, 30, 145, 336, 786, 1231, 1695, 3653], values=[2.0, 1.0, 1.0, 2.0, 1.0, 2.0, 1.0, 1.0, 2.0, 1.0]))
