Keras tensorflow problem similar to issue #104

General

1

I have already used keras and tensorflow in r. In the last days I have designed a well functioning NN with keras then I started to work on a CNN. Yesterday night I experimented some problems with the function flow_images_from_dataframe().

Trying to fix those problems I ran

reticulate::conda_install(packages= "pandas")

Then since new problems came about I ran

reticulate::conda_install(packages = "keras")

From then on problems started.
Rstudio started to abort session everytime I ran a keras command. To fix this I tried everything I could possibly find online, getting always new error codes.
Then I tried to reinstall keras and tensorflow multiple times during the day and in multiple different ways. Still When I run this:

library(keras)
library(tensorflow)
boston_housing <- dataset_boston_housing()

I get the following message:

Error: Installation of TensorFlow not found.

Python environments searched for 'tensorflow' package:
 C:\Users\mikip\Anaconda3\envs\r-reticulate\python.exe
 C:\Users\mikip\Anaconda3\python.exe

You can install TensorFlow using the install_tensorflow() function.

Even though it should be present.

If I run this again:

boston_housing <- dataset_boston_housing()

I get:

Error: Python module tensorflow.keras was not found.

I am on a tight schedule for my thesis and now I feel like I feel like I am sinking into quicksand. I would really appreciate some help.

I have never used reticulate, but i'm suspicious about you using the reticulate namespace twice, and I would think you would need to pass character vector of what to install

reticulate::conda_install("keras")

sorry, it is a typo, I will correct it.

It turnt out the version of tensorflow was not compatible with my computer I had to downgrade tensorflow to 2.1.
