trouble installing Tensorflow

[hmei617]

I tried installed keras in R Studio with the following command but it's not working
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()

Everything seems to run fine until it get to the end where it tries to activate Tensorflow
C:\Windows>conda.bat activate "r-tensorflow"

(r-tensorflow) C:\Windows>"C:\Users\username\AppData\Local\r-miniconda\envs\r-tensorflow/python.exe" -m pip install --upgrade --no-user "tensorflow==2.13." tensorflow-hub tensorflow-datasets scipy requests Pillow h5py pandas pydot

In addition: Warning message:

I also noticed the version of the python.exe installed in C:\Users\users\AppData\Local\r-miniconda\envs\r-tensorflow
is version 3.12.0 which i read is not compatible with tensorflow

Below is the output from the following codes

You can install TensorFlow using the install_tensorflow() function.

Run reticulate::py_last_error() for details.
Restart the R session and load the tensorflow R package before reticulate has initialized Python, or ensure reticulate initialized a Python installation where the tensorflow module is installed.

i would appreciate if someone could provide feedback on why it not installing. I've been working on this for days and not making any progress. thank you

Hi, sorry you're having issues. We no longer recommend using miniconda, and now recommend using a virtual environment. Can you please follow the instructions in the "Installation Issue" template and report back?

Hi, I am experiencing the same installation problem with install_keras().
I work on a MacBook M3 Pro, Sonoma 14.1.1
After trying the installation procedure I have used before, I tried the installation procedure you mentioned above, but install_keras() gives the same error:

• /Users/F102073/.virtualenvs/r-tensorflow/bin/python -m pip install --upgrade --no-user 'tensorflow==2.13.' tensorflow-hub tensorflow-datasets scipy requests Pillow h5py pandas pydot

[t-kalinowski]

Python 3.12 is too new for the current release of Tensorflow. Please install an older version of Python:

reticulate::install_python("3.10:latest")
keras::install_keras(python_version = "3.10")

[hschnack]

Thanks @t-kalinowski, now it works!
I guess I could have found these versions requirements somewhere.
It was, however, from the initial error message, not clear to me that it was a version mismatch issue between python and tensorflow.

[t-kalinowski]

Glad the fix worked! We'll improve the error message for the next release.
