尝试在R上安装keras时出错（devtools:：install_github（“rstudio/keras”）

我对R相当陌生，所以如果我的问题很琐碎，我道歉。 我尝试在R上安装keras（版本3.4.1）。我安装了包devtools，但是当我下载keras时

devtools::install_github("rstudio/keras") 

我得到下一个错误：

当我尝试通过安装它时

install.packages("keras")

我收到下一条警告信息：

also installing the dependencies ‘cli’, ‘testthat’, ‘processx’,     
‘tensorflow’

Warning message in install.packages("keras"):
“installation of package ‘cli’ had non-zero exit status”Warning

在那之后，通过

library('keras')

给予

Error in library("keras"): there is no package called ‘keras’
Traceback:

1. library("keras")
2. stop(txt, domain = NA)

如何修复它？提前谢谢！

RStudio在其网站上有一个优秀的TensorFlow with R演练！请查看完整的安装和使用文档

要为R安装Keras，请执行以下操作：

devtools:：install\u github（“rstudio/keras”）

然后，在使用

devtools

从GitHub克隆

rstudio/keras

之后：

库（keras）
安装keras（）

您是否先试用了CRAN版本？

安装程序包（“keras”）

@kluu，当我尝试这样做时，我会收到一条长长的警告消息（我会将其添加到问题中），然后通过“library”（“keras”）加载keras'不起作用。嗯……您是否为Python安装了tensorflow和keras？@kluu是的，我安装了。如果有帮助，我使用带R内核的ipython笔记本。好的……我正在尝试在新的VM上重现错误。您能试着在R控制台中运行相同的命令吗？
