Examples

set.seed(123)
n <- 50 ; p <- 3
X <- matrix(rnorm(n * p), n, p) # no intercept!
y <- rnorm(n)

obj <- nnetsauce::Ridge2Regressor(n_hidden_features = 5L)
#> Error in reticulate::use_virtualenv(venv_path, required = TRUE): Directory ./venv is not a Python virtualenv
print(obj$fit(X, y))
#> Error: object 'obj' not found
print(obj$score(X, y))
#> Error: object 'obj' not found
