py_install

Install Python packages

Description

Install Python packages into a virtual environment or Conda environment.

Usage

py_install(
  packages,
  envname = NULL,
  method = c("auto", "virtualenv", "conda"),
  conda = "auto",
  python_version = NULL,
  pip = FALSE,
  ...
)

Arguments

`packages`	A vector of Python packages to install.
`envname`	The name, or full path, of the environment in which Python packages are to be installed. When `NULL` (the default), the active environment as set by the `RETICULATE_PYTHON_ENV` variable will be used; if that is unset, then the `r-reticulate` environment will be used.
`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 for more details.
`python_version`	The requested Python version. Ignored when attempting to install with a Python virtual environment.
`pip`	Boolean; use `pip` for package installation? This is only relevant when Conda environments are used, as otherwise packages will be installed from the Conda repositories.
`...`	Additional arguments passed to `conda_install()` or `virtualenv_install()`.

Details

On Linux and OS X the "virtualenv" method will be used by default ("conda" will be used if virtualenv isn't available). On Windows, the "conda" method is always used.
