I was very excited to read Kevin Ushey's 2019-12-20 blog contribution on reticulate 1.4, since it promised to make using Python power, e.g. from tensorflow and keras, available to R and in particular to RStudio.
I'm using WIN10-64 together with R3.6.2, RStudio 1.2.5033 and RTools 3.5, and was expecting a smooth transfer from my rather ancient installation with Anaconda3 and earlier versions of reticulate, tensorflow and keras.
However, much to my disappointment, it doesn't work at all like described:
reticulate 1.4 was installed and attached; the command "library(tensorflow)" simply produced the message "object tensorflow not found"
tensorflow 2.0.0 installed and attached separately: no reaction
keras 18.104.22.168 installed and attached: reticulate starts installation of miniconda; after 2hrs of 75...100% CPU load I had to terminate R via WIN-Task-Mgr., no other option to influence the process
using reticulate::install_miniconda() starts the installation process successfully, WIN indicates Miniconda3 v4.7.12 (Python 3.7.4) to be installed correctly
attaching reticulate again - object tensorflow not found, same with keras
is_keras_available => FALSE (as expected at this stage, I must confess)
Since I have removed my (very ancient but working) keras-installation (together with previous reticulate, tensorflow, Anaconda3 as well as Python 3.7), I am at this moment unable to continue my work based on keras. Any suggestion what I could do would be highly appreciated...
Tnx in advance
