error in function to_categorical

[jobstdavid]

Hi,

running the following code

library(keras)
library(tensorflow)

mnist <- dataset_mnist()
y_train <- mnist$train$y

y_train <- to_categorical(y = y_train, 
                          num_classes = 10)

yields the error

Error in (function (x, num_classes = NULL)  : 
  unused arguments (y = c(5, 0, 4, 1, 9, 2, 1, 3, 1, 4, 3, 5, 3, 6, 1, 7, 2, 8, 6, 9, 4, 0, 9, 1, 1, 2, 4, 3, 2, 7, 3, 8, 6, 9, 0, 5, 6, 0, 7, 6, 1, 8, 7, 9, 3, 9, 8, 5, 9, 3, 3, 0, 7, 4, 9, 8, 0, 9, 4, 1, 4, 4, 6, 0, 4, 5, 6, 1, 0, 0, 1, 7, 1, 6, 3, 0, 2, 1, 1, 7, 9, 0, 2, 6, 7, 8, 3, 9, 0, 4, 6, 7, 4, 6, 8, 0, 7, 8, 3, 1, 5, 7, 1, 7, 1, 1, 6, 3, 0, 2, 9, 3, 1, 1, 0, 4, 9, 2, 0, 0, 2, 0, 2, 7, 1, 8, 6, 4, 1, 6, 3, 4, 5, 9, 1, 3, 3, 8, 5, 4, 7, 7, 4, 2, 8, 5, 8, 6, 7, 3, 4, 6, 1, 9, 9, 6, 0, 3, 7, 2, 8, 2,

I use the following version: tensorflow_2.16.0, keras_2.15.0 with R version 4.3.3 on a macbook pro m1.

Any idea why the error happens?

I use the following version: tensorflow_2.16.0, keras_2.15.0 with R version 4.3.3 on a macbook pro m1.

I believe you need to be using the keras3 package if you want to use TensorFlow 2.16.
