Problem with py_call_imp function on R

Keras
1

Following the code of a neural network based on the dataset “trees”

alberi = keras_model_sequential() %>%
layer_dense(units = 5, activation = “sigmoid”, input_shape = 2) %>%
layer_dense(units = 5, activation = “sigmoid”) %>%
layer_dense(units = 1, activation = “linear”)

summary(alberi)

alberi %>% compile(
optimizer = “adam”,
loss = “mse”,
metrics = “accuracy”
)

storia = alberi %>% fit(
x = trees[,2:3],
y = trees$Girth,
epochs = 10
)

It returns me the following error:

Error in py_call_impl(callable, dots$args, dots$keywords) :
ValueError: in user code:

Someone could help me?

Trying to fit a neural network using dataset “trees”:
