I have been using {keras} packages to run the deep learning tutorial in tensorflow.rstudio.com.
The problem is that the mnist$train$x is an array with dimension attribute c(60000, 28, 28). This is like having 60,000 28 by 28 matrices. But the way I can create an array like that in r, as far as I know, would be doing array( numeric(length = 28*28*60000), dim = c(28, 28, 60000) ), not array( numeric(length = 28*28*60000), dim = c(60000, 28, 28) ).
I just want to know how to create an array like this array(1:18, dim = c(3, 3, 2)) and change the dimension order to be c(2, 3, 3) like the array in keras::dataset_mnist()
Thanks, in advance.
