Hi

I am a newbie to Deep-learning & trying to install Keras library into R-Studio but with below error,

> library(devtools)

I had some same errors while Installing These packages , and what i finally found was that my major packages such as *Rcpp , curl ,jsonlite* were not properly installed or were outdated , so i first updated Rcpp , then
what i did was step by step installed all necessary packages with proper debugging if some errors occured--

>install.packages("devtools")
>require(devtools)
>install_github("rstudio/reticulate")
>install_github("rstudio/tensorflow")
>install_github("rstudio/keras")

After some time all these packages were installed successfully . So there might be a possibility in your case too.
Just try this out once , and just update with any other errors or complications.
Hope this was helpful.

It was the problem with reticluate version. I upgraded it & is working fine now.

Thank you very much!!

When I am trying to install TensorFlow, I Keep on receiving this error even though I updated R & R Studio & Packages. What should i do get rid of this error. & I was using the procedure given in the link. https://tensorflow.rstudio.com/installation.html & I am facing problem at the 1st command its self.

I'm not sure. This is a failure to install a package from GitHub which
could have many different sources of error. My guess is that the following
fails as well:

devtools::install_github("rstudio/reticulate")

If that fails I'd suggest updating devtools via:

install.packages("devtools")

And if that fails you may want to report an issue on the devtools
repository.

Something that worked for me:
(0) Uninstall package 'keras', if installed from CRAN.

Do following on RStudio's command line:
(1) install.packages("devtools")
(2) require(devtools)
(3) devtools::install_github("rstudio/keras")

Installation Done.

Load it by going to "Packages" tab -> Search for keras -> Check mark it.

Run examples, should work!

Good Luck

install.packages("devtools")
require(devtools)
install.packages("reticulate")
library(reticulate)
install.packages("yaml")
library(yaml)
install.packages("tensorflow")
library(tensorflow)
install_github("rstudio/keras")
library(keras)

I used the upper commands to solve this questions.
我使用了上面的几行命令解决了这个问题。希望你也如此。

install_github("rstudio/keras")

Hi, zhulinmails,
I followed your install instructions unfortunately in the last step I got the 443 port error:
install_github("rstudio/keras")
Error in curl::curl_fetch_memory(url, handle = h) : Failed to connect to api.github.com port 443: Timed out

I did try also this:
with_config(use_proxy("..................",port=..............), install_github("rstudio/keras"))

Unfortunately without sucess.. Some ideas?? Thx.

Best regards,

Vlad.

Hi Anish,

I have followed the below syntax but still getting the error. Plz advice, is there any work around to resolve it.

install.packages("devtools")
require(devtools)
install_github("rstudio/reticulate")
install_github("rstudio/tensorflow")
install_github("rstudio/keras")
library(reticulate)
library(tensorflow)
library(keras)
model_k = keras_model_sequential()
Error: Installation of TensorFlow not found.

Python environments searched for 'tensorflow' package:
C:\Users\abc\AppData\Local\r-miniconda\envs\r-reticulate\python.exe

You can install TensorFlow using the install_tensorflow() function.

Unfortunately, it just does not work in Mainland China.
