r - 在 R 上安装 TensorFlow

Question

尝试通过 install_tensorflow 安装 TensorFlow在使用 R 内核的 Google Cloud AI Platform 笔记本中:

platform       x86_64-pc-linux-gnu         
arch           x86_64                      
os             linux-gnu                   
system         x86_64, linux-gnu           
status                                     
major          3                           
minor          6.1                         
year           2019                        
month          07                          
day            05                          
svn rev        76782                       
language       R                           
version.string R version 3.6.1 (2019-07-05)
nickname       Action of the Toes

我跑:

install.packages(c("tfestimators", "tfdatasets", "cloudml", "rjson"))
library(tfestimators) # used for creating tensorflow estimators
library(tfdatasets) # used for creating data input functions
library(cloudml) # used for training and deploying models to AI Platform
install_tensorflow()

我得到:

Error in virtualenv_install(envname, packages, ...): unused arguments (python_version = conda_python_version, pip = TRUE)Traceback:1. install_tensorflow()2. reticulate::py_install(packages = c(package, extra_packages), . envname = envname, method = method, conda = conda, python_version = conda_python_version, . pip = TRUE, ...)

Answer 1

我在尝试为 R 安装 Keras 时遇到了同样的错误。从 CRAN 更新到最新的 reticulate 版本和从 Github 更新到最新的 tensorflow 版本解决了这个问题:

install.packages("reticulate")
devtools::install_github("rstudio/tensorflow")

然后

library(tensorflow)
install_tensorflow()

我使用 conda 而不是 venvs。
