完整错误:


问题:

原来的安装有问题,程序如法运行;

原来的安装方式为:

install.packages('keras')

install.packages('tensorflow')

删除已经安装的keras和tensorflow包。

remove.packages('package_name')

library(DAAG)

head(ais)

# standardise
minmax <- function(x) (x - min(x))/(max(x) - min(x))
x_train <- apply(ais[,1:11], 2, minmax)


library(keras)

# set training data
x_train <- as.matrix(x_train)
# set model
model <- keras_model_sequential()
model %>%
  layer_dense(units = 6, activation = "tanh", input_shape = ncol(x_train)) %>%
  layer_dense(units = 2, activation = "tanh", name = "bottleneck") %>%
  layer_dense(units = 6, activation = "tanh") %>%
  layer_dense(units = ncol(x_train))
# view model layers
summary(model)

解决:

安装tensorflow和keras

  • devtools::install_github("rstudio/tensorflow")
  • devtools::install_github("rstudio/keras")

接着执行如下程序:

  • tensorflow::install_tensorflow()
  • tensorflow::tf_config()

接着在library(keras)的时候又发生错误:

summary(model)

正确的输出:
