Tensorflow安装时发生错误

Question

我在r中安装了tensorflow几次，但是建模顺序部分不起作用。建模部分显示安装错误。如何用r语言解决问题？

install_tensorflow()
library(keras)
library(tensorflow)
model <- keras_model_sequential() 
model%>%layer_flatten(input_shape = c(lookback / step, dim(data)[-1])) %>% 
  layer_dense(units = 32, activation = "relu") %>% 
  layer_dense(units = 1)

Error: Installation of TensorFlow not found.

You can install TensorFlow using the install_tensorflow() function.
