Installation problems

[Allisterh]

I hope this an issue that easily resolved. I have been trying to get TensorFlow and keras to work on my machine for weeks now (windows 11). I can install both packages easily (btw I have anaconda 4.10.3 and R version 4.1.2 installed). However, whenever I close R and reopen it load the packages and try to use them I get this message:

Error: Valid installation of TensorFlow not found.

Python environments searched for 'tensorflow' package:
C:\Users\Alister\anaconda3\python.exe

Python exception encountered:
ModuleNotFoundError: No module named 'tensorflow'

Detailed traceback:
File "C:\Users\Alister\Dropbox\PC (2)\Documents\R\win-library\4.1\reticulate\python\rpytools\loader.py", line 39, in _import_hook
module = _import(

You can install TensorFlow using the install_tensorflow() function.

Please can someone tell me what is happening here is this a reticulate problem or tensorflow problem. Like I said I successfully installed TensorFlow and created a an environment in Anaconda but for the life of me it just wont work.

Have you run tensorflow::install_tensorflow() ?

[Allisterh]

This is my exact install tensorflow installation command.

install_tensorflow(method = "conda",
version = "default", envname = "py_tf",
conda_python_version = "3.9",
extra_packages = c("matplotlib", "numpy"))

[t-kalinowski]

Many installation issues are resolved by running the following in a fresh R session (you can restart R in Rstudio with Ctrl+Shift+F10) :

# install the development version of packages, in case the
# issue is already fixed but not on CRAN yet.
install.packages("remotes")
remotes::install_github(sprintf("rstudio/%s", c("reticulate", "tensorflow", "keras")))
reticulate::miniconda_uninstall() # start with a blank slate
reticulate::install_miniconda()
keras::install_keras()

Test to see if installation was successful.

tensorflow::as_tensor("Hello World")

If the above snippet succeeded and you saw something like tf.Tensor(b'Hello World', shape=(), dtype=string), then 🎉, you've successfully installed Tensorflow.

If the above installation failed, please gather some diagnostic info:

reticulate::py_config()
tensorflow::tf_config()
reticulate::import("tensorflow")
reticulate::py_last_error()
sessionInfo()

Please copy and paste the FULL OUTPUT of running all three snippets, and be sure to enclose the output lines with three backticks (```) for monospace formatting.

Thanks so much [it worked like a charm. However, I am still puzzled why the conda version of install kept failing. Nonetheless thanks o much for your kind assistance, really appreciated.

@t-kalinowski hope you are doing great.

Thanks for this solution. I got stuck in the last step.

this error:

Hi @Allisterh We no longer recommend using miniconda as the default installation path for TensorFlow.

We recommend installing Python normally, either from www.python.org, or by running reticulate::install_python(), and then running install_tensorflow().

E.g., this should work:

reticulate::install_python()
keras::install_keras()

Does it matter which version of Python you install?

[t-kalinowski]

Being on the latest Python version is generally not advisable, ~2 minor versions behind the current Python minor release version is generally the sweet spot for deep learning packages. (3.9.* or 3.10.* today). The default argument to install_python() is "3.9:latest" today, and is generally incremented in new releases when appropriate.
