Installation Issue - no valid installation of tensorflow

Start by reviewing the install_tensorflow(), tf_config(), and reticulate Python-initialization paths, using the reported Windows, Python 3.11, TensorFlow 2.18 setup to reproduce the failure. Compare the environment selected by py_config() with the environment created by installation; done means tensorflow::tf_config() and reticulate::import("tensorflow") both succeed.

Hi,

I'm having problems installing tensorflow.

I can add the following code:

install_tensorflow(envname = "C:\Users\LynseyMcColl\AppData\Local\r-tensorflow", method = "conda", python_version = "3.11", version = "2.18")

Which says the installation is successful but when I then try it out I get the following error message:
Error: Valid installation of TensorFlow not found.

I have set an envname above as I am working on one drive and so have pointed it to the desktop rather than an online environment which I've read can cause problems.

I've put the messages I get to the commands requested below.

Many thanks,

Lynsey

You can install TensorFlow using the install_tensorflow() function.
 
Warning message:
ModuleNotFoundError: No module named 'tensorflow'
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.

reticulate::import("tensorflow")

Error in py_module_import(module, convert = convert) : 
  ModuleNotFoundError: No module named 'tensorflow'
