Installation of TensorFlow not found.

lipinu commented 4 years ago

Encounter issue as tittle stated. After refer to issue #144, try all the tricks there,

I have tried uninstalling and reinstalling Anaconda, conda update --all, and then

devtools::install_github("rstudio/reticulate")
devtools::install_github("rstudio/tensorflow")
library(tensorflow)
install_tensorflow(envname = "tf")

But still can not work. Any help would be much appreciated.

my suggestion is to install anaconda and create an environment called "r-reticulate".

you can do it using anaconda navigator or

reticulate::conda_create(envname = "r-reticulate")

then to check that env detected by reticulate, use reticulate::conda_python().it must return directory of python.exe for your env. after that you can install tensorflow by install_tensorflow(). [not working in my case]

so I install the tesnorflow from CMD. follow these steps:

open the cmd :]
activate the r-reticulate env using conda activate r-reticulate (you may need your directory to conda directory if you did not add conda to your PATH)
use : conda install -c anaconda tensorflow

now in R, you can use TensorFlow. for installing Keras, you can use pip install Keras. [I tried install_keras() function after the installation of tensorflow, but it n

Hello,

The code that installs tensorflow and keras has been refactored. Please update to the latest versions of reticulate, tensorflow, and keras:

install.packages("remotes")
remotes::install_github(paste0("rstudio/", c("reticulate", "tensorflow", "keras")))
reticulate::install_miniconda() # skip this if you want to self-install conda or use venv
keras::install_keras()

Please let us know if after updating you are still encountering installation issues: https://github.com/rstudio/tensorflow/issues/new
