Install Python Learners

Source: R/install_python_learners.R
install_python_learners.Rd

Creates a conda environment and installs the packages required by the Python learners. Installs the dependencies of the fastai auto learner and the tabpfn auto learner. The learners share a single environment, so one RETICULATE_PYTHON covers both.

Usage

install_python_learners(
  learners = c("fastai", "tabpfn"),
  envname = file.path(getwd(), ".conda", "mlr3automl-python"),
  python_version = "3.12"
)

Arguments

learners

(character())
Learners to install the Python dependencies for. One or more of "fastai" and "tabpfn".

envname

(character(1))
Path to the conda environment directory. Defaults to .conda/mlr3automl-python in the current working directory.

python_version

(character(1))
Python version to use. Pinned to "3.12" by default so the environment is reproducible across machines.

Value

Invisibly returns the path to the Python binary in the environment.

Details

The environment is created in the project directory by default.

Examples

if (FALSE) { # \dontrun{
install_python_learners()
