List installed Python packages — py_list

List the Python packages that are installed in the requested Python environment.

py_list_packages(
  envname = NULL,
  type = c("auto", "virtualenv", "conda"),
  python = NULL
)

Arguments

envname: The name of, or path to, a Python virtual environment. Ignored when python is non-NULL.
type: The virtual environment type. Useful if you have both virtual environments and Conda environments of the same name on your system, and you need to disambiguate them.
python: The path to a Python executable.

Value

An R data.frame, with columns:

package: The package name.
version: The package version.
requirement: The package requirement.
channel: (Conda only) The channel associated with this package.

Details

When envname is NULL, reticulate will use the "default" version of Python, as reported by py_exe(). This implies that you can call py_list_packages() without arguments in order to list the installed Python packages in the version of Python currently used by reticulate.
