install_keras

Install TensorFlow and Keras, including all Python dependencies

Description

This function will install Tensorflow and all Keras dependencies. This is a thin wrapper around tensorflow::install_tensorflow(), with the only difference being that this includes by default additional extra packages that keras expects, and the default version of tensorflow installed by install_keras() may at times be different from the default installed install_tensorflow(). The default version of tensorflow installed by install_keras() is “2.9”.

Usage

 
install_keras( 
  method = c("auto", "virtualenv", "conda"), 
  conda = "auto", 
  version = "default", 
  tensorflow = version, 
  extra_packages = NULL, 
  ..., 
  pip_ignore_installed = TRUE 
)

Arguments

Arguments	Description
method	Installation method. By default, “auto” automatically finds a method that will work in the local environment. Change the default to force a specific installation method. Note that the “virtualenv” method is not available on Windows.
conda	The path to a `conda` executable. Use `"auto"` to allow `reticulate` to automatically find an appropriate `conda` binary. See Finding Conda and `conda_binary()` for more details.
version	TensorFlow version to install. Valid values include: - `"default"` installs 2.9 - `"release"` installs the latest release version of tensorflow (which may be incompatible with the current version of the R package) - A version specification like `"2.4"` or `"2.4.0"`. Note that if the patch version is not supplied, the latest patch release is installed (e.g., `"2.4"` today installs version “2.4.2”) - `nightly` for the latest available nightly build. - To any specification, you can append “-cpu” to install the cpu version only of the package (e.g., `"2.4-cpu"`) - The full URL or path to a installer binary or python *.whl file.
tensorflow	Synonym for `version`. Maintained for backwards.
extra_packages	Additional Python packages to install along with TensorFlow.
…	other arguments passed to `reticulate::conda_install()` or `reticulate::virtualenv_install()`, depending on the `method` used.
pip_ignore_installed	Whether pip should ignore installed python packages and reinstall all already installed python packages. This defaults to `TRUE`, to ensure that TensorFlow dependencies like NumPy are compatible with the prebuilt TensorFlow binaries.

Details

The default additional packages are: tensorflow-hub, tensorflow-datasets, scipy, requests, pyyaml, Pillow, h5py, pandas, pydot, with their versions potentially constrained for compatibility with the requested tensorflow version.
