    if (FALSE) { # testthat utilty for skipping tests when Keras isn't available skip_if_no_keras <- function(version = NULL) { if (!is_keras_available(version)) skip("Required keras version not available for testing") } # use the function within a test test_that("keras function works correctly", { skip_if_no_keras() # test code here }) }
