Deprecated use of keras causes error in example code.

[m-r-munroe]

I went to here to work through the R-keras example:
https://tensorflow.rstudio.com/guide/keras/

There is a command 'predict_classes' that is now deprecated in keras.

--> if I knew how to insert images, I would put the screenshot of the error here <--

You should keep your help documentation reasonably current.

The way to get it to work is:
model %>% predict(x_test) %>% k_argmax()

Here's what I observed in terms of the warning:

1: In keras::predict_classes(object = object$fit, x = as.matrix(new_data)) :
  `predict_classes()` is deprecated and and was removed from tensorflow in version 2.6.
Please update your code:
  * If your model does multi-class classification:
    (e.g. if it uses a `softmax` last-layer activation).

      model %>% predict(x) %>% k_argmax()

  * if your model does binary classification
    (e.g. if it uses a `sigmoid` last-layer activation).

      model %>% predict(x) %>% `>`(0.5) %>% k_cast("int32")
