Can't compile svm example

[wormtql]

I'm executing exactly the same code as the winequality_svm example, with my Cargo.toml as close as possible to the example Cargo.toml

[package]
name = "svm_example"
version = "0.1.0"
edition = "2021"

[dependencies]
linfa-svm = "0.7.0"
linfa = "0.7.0"
linfa-datasets = { version = "0.7.0", features = ["winequality", "diabetes"] }
ndarray = "0.15"
num-traits = "0.2"
linfa-kernel = "0.7.0"

My rust toolchain is nightly 1.83.0
And got the compiler error:

same error for me with rustc 1.80.0 (051478957 2024-07-21)
