Install Python Dependencies Offline

Source: R/cohort_contrast_viewer.R
installPythonDepsOffline.Rd

Installs Python packages from pre-downloaded wheel files (offline installation). This is useful for air-gapped servers without internet access.

Usage

installPythonDepsOffline(
  packagesDir = NULL,
  platform = "linux_x86_64",
  cleanup = TRUE
)

Arguments

packagesDir

Path to directory containing wheel files or a .zip archive. This argument is required in CRAN builds.

platform

Platform identifier. Default is "linux_x86_64".

cleanup

Logical. If TRUE, removes extracted files after installation. Default is TRUE.

Value

Invisibly returns TRUE if installation was successful.

Details

The function supports two formats:

  • A .zip file (e.g., "linux_x86_64.zip") containing wheel files

  • A directory containing .whl files directly

For offline installation:

  1. Download wheel files on a machine with internet access

  2. Copy the packages folder to the offline server

  3. Run this function to install from local files

Examples

if (FALSE) { # \dontrun{
packagesDir <- Sys.getenv("COHORT_CONTRAST_WHEELS")
if (interactive() &&
    requireNamespace("reticulate", quietly = TRUE) &&
    nzchar(packagesDir) &&
    dir.exists(packagesDir)) {
  configurePython(createVenv = FALSE)
  installPythonDepsOffline(packagesDir = packagesDir)
}
} # }
