cran <- getOption("repos")
cran["dmlc"] <- "https://s3-us-west-2.amazonaws.com/apache-mxnet/R/CRAN/"
options(repos = cran)
install.packages("mxnet")


错误：

Error: package or namespace load failed for ‘mxnet’:
 object ‘set_global_graph_attrs’ is not exported by 'namespace:DiagrammeR'
解决：

# Make sure you have devtools installed already
require(devtools)
install_version("DiagrammeR", version = "0.9.0", repos = "http://cran.us.r-project.org")
require(DiagrammeR)
