I have installed tensorflow in r with this code install_tensorflow(conda_python_version = '3.8').
When calling tf$constant('Hellow Tensorflow'), I get this error:
Error: Installation of TensorFlow not found.
Python environments searched for 'tensorflow' package:
C:\Users\User\.conda\envs\r-reticulate\python.exe
C:\ProgramData\Anaconda3\python.exe
You can install TensorFlow using the install_tensorflow() function.
However, I have the python.exe in the first location and have the library in C:\Users\User\.conda\envs\r-reticulate\Lib\site-packages\tensorflow\. Why the tensorflow installation could not be found?
I have solved this by typing conda activate r-reticulate to anaconda powershell while having the tensorflow installed in the r-reticulate environment.

I would like to install Keras and Tensorflow for R and I don't know why but I can't. I got a Miniconda installation though.
Even if I try to use my Miniconda path I still have the same error when I try to install Keras or Tensorflow I get the same error.
Here's my code:
use_condaenv("miniconda3", required = TRUE)
install.packages('keras')
install.packages('tensorflow')
library(keras)
library(tensorflow)
install_keras()
install_tensorflow()
The error comes with install_keras() (or install_tensorflow(), whatever the first row is):
Error: installation of 'python=3.7' into environment '.../r-miniconda/envs/r-reticulate' failed [error code 1]
But this is not my miniconda3 path. I'm using this path for r-reticulate in order to generate R Markdown documents including both R and Python code.
Is there a simple way to install Keras and Tensorflow for R?
Thanks so much
First, we need to make sure we have DevTools installed so we can import the necessary packages, then install Keras.
install.packages("devtools")
devtools::install_github("rstudio/keras")
I'm using windows, my problem is that while trying to install tensorflow in R the following error message appears.
Error in install_tensorflow(method = method, conda = conda, version = tensorflow, :
Unable to install TensorFlow on this platform.Binary installation is only available for 64-bit platforms.
My machine is 64 bit, so I don't understand where is the problem.
I've already cheked if my anaconda installation and the python version are 64bit and they are.
I can install tensorflow in python without any error, but i can't in R.
I've tried to redirect the R tensorflow installation to the python environment but i don't know if it can really help.

Error in install_tensorflow() :

Can you try to install older version of tensorflow which is 1.5.0 using command pip install tensorflow==1.5.0
I am trying to install tensorflow on R. As far as I understand I have already installed successlly many times but it won't load
Everytime I run a function from Tensorflow and Keras it does not work.

When I load the libraries I have no issues. They all load up sucessfully.
library(EBImage)
library(keras)
library(tensorflow)
I have ran all these following commands.
install.packages("keras")
source("http://bioconductor.org/biocLite.R")
biocLite("EBImage")
install.packages("reticulate")
install.packages("remotes")
remotes::install_github("rstudio/tensorflow")

reticulate::py_discover_config("tensorflow")
install.packages("devtools")
devtools::install_github("rstudio/keras")
tensorflow::install_tensorflow()
devtools::install_github("rstudio/keras")
What could be causing the issue. After I installed tensforflow it said "Installation Complete" and then restarted R. Is R simply unable to find the installation?
I have also ran the following commands still with no luck.
library(tensorflow)
Sys.setenv(TENSORFLOW_PYTHON="/usr/local/bin/python")
Update
I was able to get Tensorflow/Keras to work by opening an Anaconda command prompt and running the following commands. Then my R code using Keras/Tensorflow started to work.
conda install -c conda-forge keras
The keras package makes use of keras through python. When you install the package, it installs the R interface, but not the python package. You must separately install the python package. There is a nice guide for doing that on RBloggers
I checked all of the suggestions. None of them worked.
This worked for me on Windows 10
1- Open rstudio and uninstall these package if you already installed using:
uninstall.packages(c("keras", "tensorflow","tfruns"))
2- uninstall rtools from your computer if exists
3- Install Anaconda from https://www.anaconda.com/products/individual
4- Install the last version of rtools from https://cran.r-project.org/bin/windows/Rtools/
5- Close rstudio if it is opened
6- open new session and write this:
install.packages("reticulate")
install.packages("remotes")
library("reticulate")
remotes::install_github("rstudio/tensorflow")
library(tensorflow)
install_tensorflow(version = "2.0.0b1", method = "conda", envname = "r-reticulate")
remotes::install_github("rstudio/keras", dependencies = TRUE)
library(keras)
7- check if they work:
#if tensorflow works
tf$abs(-1)
#if keras works
mnist <- dataset_mnist()
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
I´m trying to install Tensorflow on Rstudio windows.
I have installed, Anaconda 3, all my R librarys are updated, and load library Keras on R
When I try to install, using:
install_keras()
The installation was not completed and an error message prompt:
Error: Error 2 occurred installing packages into conda environment r-tensorflow
In addition: Warning message:
"running command '"C:/PROGRA~3/ANACON~1/Scripts/activate" r-tensorflow && pip install --upgrade --ignore-installed https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.3.0-cp36-cp36m-win_amd64.whl had status 2"
Can someone help me in this issue?
Thanks!!!
I got the same error. I think it is because tensorflow is already installed through the install of keras. If I try to install keras again, I get the error that keras and tensorflow can only be installed in a fresh R session, where they had not been installed before. Otherwise there might be dll error. So it appears to me that you do not (and should not) install tensorflow if you have already installed keras. When I stopped Rstudio and started it again, I could install keras and re-install tensorflow through.
I had Tensorflow installed with Anaconda. Now I want use it in R and I need to reinstall Tensorflow, because the note here
NOTE: You should NOT install TensorFlow with Anaconda as there are
issues with the way Anaconda builds the python shared library that
prevent dynamic linking from R.
I already tried to uninstall from Anaconda and install with pip but its came to the same place in anaconda directory. Tesorflow is working from terminal but in R shows Error: Command failed (1)
Anybody can help me to how I can solve the problem? Should I uninstall anaconda and install Tensorflow using pip?
You have several options on what to do. Probably the cleanest one is to install a system-wide python (if not installed yet) and then create a virtual environment. This basically takes your system python binaries and moves them to its own compartment where everythign is isolated from the rest, incl. anaconda. Once you are inside an activated virtual environment you can install all the necessary Python appendages for TensorFlow. Once that is done, make sure you set up a correct environmental PATH for TensorFlow from where R can reach it:
Sys.setenv(TENSORFLOW_PYTHON="/path/to/virtualenv/python/binary")
devtools::install_github("rstudio/tensorflow")
Example of the path to where you installed the virtual environment project would be, I think, something like ~/minion/medvedi/venv_medvedi/bin/python.
This is no longer an issue, the documentation was updated too.
See here:

With the help of Keras, we can install the TensorFlow package in R.
install_keras()
library(keras)
devtools::install_github("rstudio/keras")
install_tensorflow(package_url = "https://pypi.python.org/packages/b8/d6/af3d52dd52150ec4a6ceb7788bfeb2f62ecb6aa2d1172211c4db39b349a2/tensorflow-1.3.0rc0-cp27-cp27mu-manylinux1_x86_64.whl#md5=1cf77a2360ae2e38dd3578618eacc03b")
library(tensorflow)
Keras is a high-level neural network API for deep learning from TensorFlow Google.
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 ruined my TensorFlow installation also]
Eventually I found the best and fast method to do it in R:
devtools::install_github("rstudio/keras")
library(keras)
install_keras(method = "conda")
install_keras(tensorflow = "gpu")
tensorflow::install_tensorflow()
