Folks,
Sorry to bother you, but I have bad news. Normal R packages work, but
keras and tensorflow keep crashing. After 2 hours of trying to
reinstall I still have nothing.
can anybody suggest a way to install tensorflow and keras under 4.5?
(let me know if I should be posting in a different forum.)
I am pasting the script that used to work under 4.4
```
if(!requireNamespace("remotes")) install.packages("remotes")
remotes::update_packages()
remotes::install_cran(c("readr", "tibble", "zip", "fs", "listarrays"))
install.packages("reticulate")
reticulate::miniconda_uninstall()
unlink("~/.pyenv", recursive = TRUE)
unlink("~/.virtualenvs/r-reticulate", recursive = TRUE)
python <- reticulate::install_python("3.12.3")
reticulate::virtualenv_create("r-reticulate", python = python)
install.packages("keras") # keras3
install.packages("tensorflow")
keras::install_keras( envname = "r-reticulate", # keras3
extra_packages = c("keras-tuner", "ipython", "kaggle"))
```
if keras is replaced with keras3 then the install will finish, but it
keeps crashing when I try to run code.
I also discovered that google colab made it very difficult to install
keras in colab. maybe keras is meant to be on python only??
Thanks everybody
