predict_classes depricated from TensorFlow

[MotivaoCrypto]

Error in py_get_attr_impl(x, name, silent) :
AttributeError: 'Sequential' object has no attribute 'predict_classes'
In addition: Warning message:
In predict_classes(model, x_data_test) :
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")
