#' Install aif360 and its dependencies
#'
#' @inheritParams reticulate::conda_list
#'
#' @param 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. Note also
#'   that since this command runs without privilege the "system" method is
#'   available only on Windows.
#'
#' @param version AIF360 version to install. Specify "default" to install
#'  the latest release.
#'
#' @param envname Name of Python environment to install within
#'
#' @param extra_packages Additional Python packages to install.
#'
#' @param restart_session Restart R session after installing (note this will
#'   only occur within RStudio).
#'
#' @param conda_python_version the python version installed in the created conda
#'   environment. Python 3.6 is installed by default.
#'
#' @param ... other arguments passed to [reticulate::conda_install()] or
#'   [reticulate::virtualenv_install()].
