Installation Issue

Hi,

I am able to successfully install keras and tensorflow using the following lines

#desginate local path to python 
path_to_python <- "C:/Users/Hadarma/AppData/Local/Programs/Python/Python310"
#then create v_env within this version of python 
virtualenv_create("r-reticulate", python = path_to_python)
#install tensroflow and keras in v_env
install_tensorflow(envname = "r-reticulate")
install_keras(envname = "r-reticulate")
#use this v_env
use_virtualenv("r-reticulate")

However as soon as I close the .Rproject I am unable to successfully use the packages. For example if I run this line

model <- keras::keras_model_sequential()

this is the output I will receive.

Error: Valid installation of TensorFlow not found.

You can install TensorFlow using the install_tensorflow() function.

Since the above installation clearly fails, here is the info requested :)

The error messages indicate that reticulate is not binding to the virtual env "r-reticulate", but rather, to the venv starter used, ~/../AppData/Local/Programs/Python/Python310. We'll have to figure out why.

In a fresh R session, what is the output from running:

library(reticulate)
use_virtualenv("r-reticulate")
py_config()

If that succeeds, then likely the RStudio IDE is redirecting reticulate to select the "wrong" python installation. You can modify or disable this IDE feature under "Tools > Global Options > Python". My recommendation is to disable the IDE feature (uncheck the box, leave the text field empty"), and to do all reticulate/python managment from either a project local .Rprofile or .Renviron, or at the start of your project R scripts.

If that fails, then please post the full output from running these commands that venv from scratch, and we'll try to figure out the cause:

# restart R session, Ctrl+Shift+F10 
tensorflow::install_tensorflow(envname = "r-reticulate", version = "release", new_env = TRUE)
use_virtualenv("r-reticulate")
py_config()

Hi Tomasz,

I sort of figured out that the issue had to do to with the interpreter and I also discovered the "Tools > Global Options > Python" settings. What I found worked on that specific computer was to allow the Python Interpreter to access virtual environments and I used this bit of code.

#make sure in global options the virtual environment is selected as a python interpreter
#also make sure using a fresh R session 

#load libraries 
install.packages("tensorflow")
install.packages("keras")
library(reticulate)
library(keras)
library(tensorflow)

#create virtual environment 
virtualenv_create("myenv")
#use the virtual environment we names "myenv"
use_virtualenv("myenv")
#finally install the package in the same place 
install_keras(method="virtualenv", envname="myenv")
#to the same for tensorflow
use_virtualenv("myenv")
install_tensorflow(method="virtualenv", envname="myenv")


#test to see if actually works 
tensorflow::as_tensor("Hello World")

After doing this and checking the "Global Options" I was able to start a new R session and the installation remained. However, I would like to solve it the proper way, because as soon as I tried on a colleagues computer I ran into other issues which may be due to an outdated version of Python i.e. 3.9 v. on my computer 3.10? (see below at the end of the thread)

So in a fresh R session I ran

library(reticulate) 
use_virtualenv("r-reticulate") 

Warning message:

Is this the output expected?

When you say uncheck the box in "Tools > Global Options > Python" you mean uncheck "Automatically activate project-local Python environments" and not to select any Python Interpreter (see picture)

This is from my colleagues computer when running the same lines you requested:

Thanks so much!

Progress! It looks like you have things in a working state now. We should still aim to get rid of the warning.

Two notes:

There is no need to call both install_tensorflow() and install_keras(). One or the other. (I know it's slightly confusing, and the story will change yet again with keras3. When in doubt, use install_keras(), which will install tensorflow, along with some other commonly used packages. Prefer install_tensorflow() if you want a more "minimal" installation where you'll be using only tensorflow.
This warning (condensed) should be tracked down.

Warning message:
Previous request to `use_python("myenv")` will be ignored. It is superseded 
by request to `use_python("r-reticulate")`

Somewhere in your system setup, you have dueling python installation preference commands. They might be in .Rprofile or in other scripts you are sourcing. It's better to get a handle on this now and make sure you are only pointing reticulate at a particular python once, from one location. This is purely a sanity-preserving recommendation.

Note that in many situations, there is no need to point reticulate at a python, at all.
If you call install_keras(), it will create a venv that will automatically be discovered by reticulate. Similarly, if you want to make a project specific venv, you can do install_keras(envname = "./venv") and reticulate will automatically discover that also.

This might be helpful: https://rstudio.github.io/reticulate/articles/versions.html#order-of-discovery

Hi Tomasz,
Thanks for the detailed response and tips!

In the first attempt at installation I tried to point r-reticulate to the local Python version installed here "C:/Users/Hadarma/AppData/Local/Programs/Python/Python310" and then created a venv is this the preferred method?

From what I am seeing based on your comments you should be able to use keras and or tensorflow just with a venv which r-reticulate can create if it's not already created.

Is this correct?
Thanks!

@t-kalinowski

Hi @t-kalinowski,

Me again. I am still trying to install tensorflow on various computers for my team and I am not always successful.

Today just to see if my venv was working properly I downloaded version 3.8 Python and saved that path of the executable to feed into `reticulate::virtualenv_create("r-reticulate", python = path_to_python).

This line install_tensorflow(envname="r-reticulate"), doesn't give me an error but when I try to check the installation I receive a python error that the module isn't found so I tried some simpler packages like this py_install("pandas")and thenpandas <- import("pandas") which works perfectly.

I am thinking maybe this has to do with the tensorflow installation from github? remotes::install_github("rstudio/tensorflow") is this possible?

See terrible picture of screen, the error is basically "unhashable type list". I have been working on these installations for weeks and on 2 computers it works fine and all of the rest is doesn't. Right now I am using a formatted computer and started completely fresh.

Thanks!

Restarting R session...

After weeks of trying to install tensorflow on various windows computers I keep running into the same issues.
They mainly arise when a Python package manager such as anaconda is installed on the computer, but not only.

I have narrowed it down to these some error messages that no matter which virtual environment I use or which binary .exe of Python I download (between Python3.8-3.11) keep repeating themselves.

As it is a windows computer I have seen various solutions for the SSL but they are linux solutions.

These are the most popular error messages: The Git Path, the SSL connection, and the Python exception

We really want to be able to use tensorflow on a windows computer either using a python binary for a specific version or a virtual environment.
Thanks!

Thanks. A few notes:

Is git installed? Would you be able to install from https://git-scm.com/downloads ? I think this will resolve most of your issues.
If you can't install git, can you install a non-conda Python? I.e., the official binaries from https://www.python.org/downloads/ ?
Generally, creating Python environments in OneDrive is a recipe for trouble. Can you change the install location to one that is outside of OneDrive? I.e., do something like:
```
cat("", "WORKON_HOME=~/../.virtualenvs", "", sep = "\n",
    file = "~/.Renviron", append = TRUE)
```

Hi!
I can try to install Git, but I have official binaries of python installed as well, like mentioned in the tutorial between versions 3.8-3.10 and this doesn't seem to help.

I agree regarding the OneDrive, I have run into that issue before.

Please advise how to set up the installation using a python binary correctly.

Thanks!

Where is Git installed? Is that location on PATH? (In R, what does Sys.which("git") return). If git is not on the PATH, can you add it to PATH?

Where is Python installed? What does reticulate::virtualenv_starter(all = TRUE) find?
virtualenv_starter() should find all Pythons installed in common and default locations, but if you have a custom location then you'll need to help point reticulate at it, or pass a path to TensorFlow explicitly.

To use a specific Python executable to create the "r-tensorflow" venv, you can supply a path to python_version, like this:

install_tensorflow(python_version = "/path/to/bin/python"`)

You can also set the R option reticulate.virtualenv.starter or the env var RETICULATE_VIRTUALENV_STARTER to a path where Pythons are installed, or a : delimited list of paths.

Hi Tomasz,

I successfully installed Git using the default parameters and when I ran this line Sys.which("git") it returns "" and not a path for where PATH of Git.

I did however use install_tensorflow(python_version = "/path/to/bin/python") using my specific exectuatble and then the installation worked. I am not sure if this is related to the fact the reticulate can now use Git.

I have additional computers to install on so I hope this workaround will be a[appropriate for all!

Thank you so much for your time!

If Sys.which("git") return "", then git is not on your PATH.

If I remember correctly, the git installer provides an option to place it on the PATH for you? Rerunning the installer and checking the option might be the most accessible solution. You can also place the directory where git.exe is on PATH yourself. Here are two of the top google search results for "setting PATH windows" which at a glance look right to me:
