Keras @ Error: Python module tensorflow.keras was not found.

azhangbojun · January 13, 2021, 10:10am

Hello,
I just paid for the membership for RStudio Cloud, and the same error happened for Keras.

Here is the local version RStudio problem for this. It is same.
https://forum.posit.co/t/keras-running-error/93005/2

I don't know if you guys can have a look at my running history.
My RStudio account is 15903958811@139.com

Now if I run model <- keras_model_sequential()
It will say

Error: Python module tensorflow.keras was not found.

Detected Python configuration:

python:         /home/rstudio-user/.local/share/r-miniconda/envs/r-reticulate/bin/python

numpy_version:  1.19.5

It happened all same with the cloud version RStudio and local, all I want is just running the CNN in R.
It is so hard.
May someone help me, please?

Hello,
I got some problem for keras in R. But tensorflow is running well in python.
When I use
model <- keras_model_sequential()

I got error message:
Error:
Python module tensorflow.keras was not found.

Detected Python configuration:

python: C:/Users/DELL/AppData/Local/r-miniconda/envs/r-reticulate/python.exe

numpy: C:/Users/DELL/AppData/Local/r-miniconda/envs/r-reticulate/Lib/site-packages/numpy
numpy_version: 1.19.5

Then I tried as [R keras package Error: Python module tensorflow.contrib.keras.python.keras was not found - Stack Overflow] said, tried to install tensorflow,

library(tensorflow)
install_tensorflow(package_url = "https://pypi.python.org/packages/b8/d6/af3d52dd52150ec4a6ceb7788bfeb2f62ecb6aa2d1172211c4db39b349a2/tensorflow-1.3.0rc0-cp27-cp27mu-manylinux1_x86_64.whl#md5=1cf77a2360ae2e38dd3578618eacc03b")

but it was saying:
Collecting package metadata (current_repodata.json): ...working... failed

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

Error: installation of 'python=3.6' into environment 'C:/Users/DELL/AppData/Local/r-miniconda/envs/r-reticulate' failed [error code 1]

Then I tried to install tesorflow in Rstudio Cloud, but the installing process was killed, so I guess because of I am in the free version.

Then I tried

library(tensorflow)
use_condaenv("keras-tf", required = T)

but
Error in use_condaenv("keras-tf", required = T) :
Unable to locate conda environment 'keras-tf'.

So, how should I come to solve this problem?

Hi @azhangbojun,

Have you tried using a virtual environment instead of miniconda, as suggested in this post: Error in Installing Keras on RStudio Cloud ?

I believe the important pieces are:

library(reticulate)
library(keras)
virtualenv_create("myenv")
install_keras(method="virtualenv", envname="myenv")

Please let me know if this helps or not!

Yes, I tried, but it did not work.

I used

library(reticulate)
library(keras)
virtualenv_create("myenv")
install_keras(method="virtualenv", envname="myenv")

It was showing

Restarting R session...

Looks well but if I tried

model <- keras_model_sequential()

it was saying

Thank you!

Have you started from a new project completely? Those errors seem to reference r-miniconda still

I think you need this part at the top, and I was missing a step before:

library(reticulate)
library(keras)
virtualenv_create("myenv")
use_virtualenv("myenv")
install_keras(method="virtualenv", envname="myenv")
use_virtualenv("myenv")

In the portion below, Ming provides a slight tweak of having to use_virtualenv again after the R session reloads. That seems to have solved the problem for that user

Can you please try in a new project, following the instructions above?

Thanks in advance!

Sorry, you need to install the packages first, R is not my area of expertise, my apologies!

andy_kipp · January 15, 2021, 9:27pm

Is this a disk space issue? Can you run df -h from the terminal and paste the output?

Hello,
Is it possible to solve this problem?
Thank you!
