install_keras {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 "2.15".

Usage

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

Arguments

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 2.16

• "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.

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.
