BoundsError during eval_tree_array

[DenisSvirin]

I make new inputs r = [6.332061275761631 5.051237472144821 2.7 4.2690748412273125 3.3068111527572905 5.4 4.676537180435969 6.037383539249433 5.727564927611035 3.818376618407357 1.9091883092036785].

and execute _eval_tree_array
like this result, finished = _eval_tree_array(tree, r, operators, (turbo ? Val(true) : Val(false)))

its working for some time and then error occurs.
BoundsError: attempt to access 1×11 Matrix{Float32} at index [2, 1:11]

I understood that it comes from deg0_eval -> return (cX[tree.feature, :], true)

May be i should define r differently ? i don't understand where it finds other features

What is your tree? It looks like your expression has a feature=2 node, which is out-of-bounds for your input data. i.e., you would need to provide a 2D array with dimensions 2x11 instead.

[DenisSvirin]

its necessary for the target function, as i need to evaluate functions not over cX, but r which is calculated from cX.r can change its length

[MilesCranmer]

cX has what shape?

[DenisSvirin]

1x 40

[MilesCranmer]

Hm, that’s a bug then. There’s no way for any tree to be created that indexes larger than first axis. Can you put all your code into a bug report?

[DenisSvirin]

ok
