\l p.q
np:.p.import`numpy
Logistic:.p.import[`sklearn.linear_model;`:LogisticRegression]
train_X_np: np[`:array](1 2 3)
train_Y_np: np[`:array](0 1 1)
Logistic[`:fit][train_X_np;train_Y_np]
When I run this I get:
call: fit() missing 1 required positional argument: 'y'
What am I doing wrong?
(Also normally, there should be a .reshape(-1,1)
on the X
array, I wonder if this is the cause?)
You need to initialise the LogisticRegression object
You need to reshape the x input
q)Logistic:.p.import[`sklearn.linear_model;`:LogisticRegression][] q)train_X_np: np[`:array][1 2 3][`:reshape;-1 1] q)Logistic[`:fit][train_X_np;train_Y_np] / To predict q)Logistic[`:predict][np[`:array][0 1 2][`:reshape;-1 1]]` 0 1 1
You could also use flip enlist 1 2 3
kdb list before passing it to numpy instead of reshaping
